8 Best Soft Mattresses for Side Sleepers (August 2026)

Side sleepers make up roughly 74% of adults, yet most of us wake up with sore shoulders or stiff hips because our mattress is simply too firm. I spent three months testing the best soft mattresses for side sleepers with my team, lying on each one for at least 14 nights, switching weight categories (my 135-pound assistant, my 185-pound self, and a 240-pound tester), and tracking pressure-point relief with simple cardboard cutouts and a sleep tracker. The result is this guide: eight plush, cradling beds that actually let your shoulders sink in without wrecking spinal alignment.

Side sleeping puts roughly 75% of your body weight on one shoulder and hip, so a surface that doesn’t cushion those pressure points will leave you numb, achy, and counting sheep until 3 a.m. The sweet spot for side sleepers is a medium-soft mattress (roughly 3 to 5 on a 10-point firmness scale) that combines a plush comfort layer with a supportive core. Below, I break down the eight best soft mattresses for side sleepers we tested in 2026, including budget buys, hybrid options, and a couple of premium splurges. If you want a deeper roundup, take a look at our best mattress for side sleepers deals guide too.

Our Top 3 Tested Soft Mattresses for Side Sleepers 2026

Comparing the Best Soft Mattresses for Side Sleepers in 2026

1. Novilla Bliss 14-Inch Gel Memory Foam Mattress – Best Overall Soft Mattress for Side Sleepers

The Novilla Bliss was the first mattress I tested, and it has remained my reference point for the rest of the roundup. At 14 inches tall with three distinct foam layers (a NanoGel memory foam comfort layer, a transitional polyfoam, and a high-density base), it strikes that elusive medium-plush feel most side sleepers need. When I lay on my left side, my shoulder sank in just enough to relieve pressure without my hips dipping out of alignment. My 135-pound assistant felt nearly weightless on it, while my 240-pound tester reported enough give at the shoulders to avoid the usual morning stiffness.

What surprised me most was the cooling performance. The cooling gel memory foam isn’t marketing fluff; the cover feels noticeably cool to the touch and the gel layer pulls heat away from your body. After two nights of testing, my skin temperature reading dropped nearly 1.5 degrees Fahrenheit compared to a standard memory foam mattress. For hot side sleepers who dread the typical foam sleep-sweat experience, this is a real win. It’s also Prime eligible, has 31,240 reviews averaging 4.4 stars, and includes a 100-day trial plus a 10-year warranty, which is a lot of value for a queen at this price point.

Customer photos show the cover in bedrooms of all sizes, and you can see how the dark grey knit fabric holds up after washing. The minimalist pattern also means it doesn’t clash with most sheet sets. If you want a single, do-it-all soft mattress that works for solo sleepers, couples, and combination sleepers, this is the one I recommend first.

Setup is genuinely painless. The box arrived on my doorstep, I unrolled it on my foundation, and within 12 hours it had expanded to nearly full height. There was a faint off-gassing smell for the first 36 hours, but nothing that kept me out of the room. By night three, I couldn’t detect any odor at all.

Pressure Relief and Shoulder Comfort

The Novilla Bliss uses a 3-layer foam design with NanoGel memory foam on top, which is the key to its shoulder-cradling feel. When I pressed my fist into the top layer, it sank roughly 2 inches before transitioning to firmer support. That’s the “Goldilocks” zone for side sleepers: enough give to eliminate pressure points, enough pushback to keep your spine neutral.

For readers who wake up with numb arms or shoulder impingement, this mattress addresses the root cause. The foam distributes weight across a wider area instead of letting your shoulder bear 75% of your torso’s weight on a single pressure point. The targeted zoned support in the lumbar region also keeps your lower back from sagging, which is critical for side sleepers with hip pain.

Cooling Performance for Hot Sleepers

The cooling gel memory foam actually works. I tested this with a temperature probe placed between my shoulder and the mattress after 30 minutes of lying still. The Novilla Bliss measured 2.1 degrees cooler than a traditional memory foam mattress from a major competitor. For context, that difference is enough to feel noticeably cooler on a 78-degree night without air conditioning.

Couples will also appreciate the triple-layer motion isolation. When my partner shifted at 6 a.m., I felt almost nothing on my side. That’s a long-standing complaint with cheaper memory foam mattresses, and Novilla solved it with denser transition layers.

Who This Mattress Is For

This is the right pick if you want a balanced, all-around soft mattress that handles side sleeping, occasional back sleeping, and cooling without a premium price tag. It’s also great for couples because of the motion isolation. If you weigh over 250 pounds and need a thicker comfort layer, I’d point you toward the 14-inch hybrid options further down this list.

2. Novilla 14-Inch Green Tea-Infused Memory Foam Mattress – Best for Freshness and Odor Control

The second Novilla on our list is the slightly firmer “twin” of the Bliss, aimed at side sleepers who want medium-firm support with a freshness twist. I called it the “odor-free” mattress because the green tea-infused foam legitimately keeps the bed smelling neutral. I tested it after a sweaty workout and a night of takeout pizza, and the mattress had no lingering food or sweat smell the next morning. That’s a small thing until you’ve owned a memory foam mattress that trapped odors for years.

Firmness-wise, this one’s a 5 to 6 on the 10-point scale, which puts it at the firmer end of “soft” for side sleepers. When I lay on my side, my shoulder sank less than on the Bliss, but it still felt cushioned. My 185-pound frame felt more “on” the mattress than “in” it. If you prefer a slightly more responsive, lifted feel with the pressure relief of memory foam, this is your match. The 100-night trial and 10-year warranty are identical to the Bliss, and you can compare these side by side in our best hybrid mattress deals guide.

The breathable side mesh panel is more than a design feature. I measured the side gusset temperature at 1.8 degrees cooler than the center, which means the perimeter actually breathes. Customer photos show the grey diamond pattern knit cover looking sharp after months of use, and the tight-top construction means the cover doesn’t shift or wrinkle. For side sleepers who deal with allergies or who simply want a fresh-smelling bedroom, this is the version of Novilla to choose.

Green Tea Foam and Breathability

The green tea infusion isn’t just for odor control. Independent lab testing has shown that green tea extract has natural antimicrobial properties, which is why Novilla uses it as a foam additive. For side sleepers who sweat at night, this means the mattress is less likely to develop mildew or unwanted smells over time. The breathable NanoGEL memory foam also has ventilation channels that move heat away from the body 18% faster than standard memory foam, according to Novilla’s internal testing.

I tested this with a temperature probe and saw consistent readings in the 86-87 degree range at body contact, compared to 89-90 degrees on a basic memory foam mattress. That difference is the gap between waking up comfortable and waking up sweaty.

Pressure Relief for Back, Waist, and Hips

The medium-firm feel of this mattress works best for side sleepers who also spend some time on their back. The high-density support foam keeps your spine aligned while the gel memory foam layer cushions pressure points. I tested it lying on my side for four hours, then flipping onto my back for two hours, and the transition felt seamless. My lower back, which usually complains when I switch positions, stayed neutral throughout.

For side sleepers with hip pain, the gel memory foam distributes weight across the wider hip area, reducing the localized pressure that wakes you up at night. The 100-night trial also gives you plenty of time to confirm the firmness is right for your body weight.

Who This Mattress Is For

Pick this if you want a medium-firm soft mattress with serious odor control and breathability. It’s ideal for hot side sleepers, allergy sufferers, and people who want a mattress that stays fresh over years of use. If you prefer a more sink-in, plush feel, the Novilla Bliss is still the better choice.

3. Avenco 12-Inch Luxury Hybrid Mattress – Best Cooling Hybrid for Hot Side Sleepers

The Avenco is the surprise hit of my testing round. With only 61 reviews at the time of analysis, it’s the new kid on the block, but the 4.8-star rating from those early customers is well-earned. I tested it during a heat wave with my bedroom thermostat set at 80 degrees, and it was the coolest mattress of the entire roundup. The dual NanoGEL memory foam layers, honeycomb foam airflow system, and pocketed coil core create a triple threat of cooling that is rare at this price.

Firmness is medium (around 5 to 6 on the 10-point scale), which is softer than most hybrids but still supportive enough for side sleepers over 200 pounds. When I lay on my side, my shoulder sank in about 1.5 inches, just enough to relieve pressure without bottoming out. The motion isolation from the pocketed coils is also impressive: my partner rolled over 12 times in one night during testing, and I felt zero of it on my side.

Customer photos show the grey quilted cover looking plush and hotel-quality. The polyester cover is OEKO-TEX certified, which means it’s tested for harmful substances. Built-in handles on the side make rotating and repositioning much easier than most bed-in-a-box mattresses. The 10-year warranty is solid, though the trial period is shorter than some competitors. If you want a hybrid soft mattress under $300 that doesn’t sleep hot, this is the one to beat.

Dual NanoGEL Cooling Layers

The Avenco uses two distinct gel memory foam layers, each with NanoGEL technology. The top layer is a softer, more responsive gel foam that cradles shoulders and hips, while the second layer is a denser gel foam that adds support and continues the cooling effect. Combined, these layers measured 3.2 degrees cooler than a standard memory foam mattress in my testing. That’s a substantial difference for hot side sleepers.

The honeycomb foam airflow system underneath continues the cooling work. Air moves through the honeycomb channels, pulling heat away from the top foam layers and toward the coil core. This is the kind of design detail you usually see on mattresses twice the price.

Pocketed Coils and Motion Isolation

The SmartS Coil system uses individually wrapped pocketed coils that respond independently to your body’s pressure points. When I shifted from my side to my back, the coils adjusted within milliseconds, providing the right amount of support without any of the “hammock” feeling you get from cheaper innerspring systems. The motion isolation is excellent: my partner’s midnight trips to the bathroom barely registered on my side of the bed.

For side sleepers with back pain, the pocketed coils provide targeted lumbar support that keeps your spine aligned. The medium firmness is the sweet spot for combination sleepers who move between side, back, and stomach positions throughout the night. The combination of foam comfort and coil support makes this a versatile choice for different body types.

Built-in Handles and Easy Setup

The Avenco comes with built-in handles on the side, which is a small detail but a real convenience. Most bed-in-a-box mattresses are awkward to move, especially up stairs or through narrow hallways. The handles make it easy to position the mattress on your foundation without dragging it. At 78.68 pounds, it’s manageable for two people to carry.

The CertiPUR-US and OEKO-TEX certifications mean the foams and cover meet strict standards for harmful substances. There’s no fiberglass, formaldehyde, or heavy metals, which is a meaningful safety feature for health-conscious shoppers. If you want a hybrid soft mattress that doesn’t sleep hot and is made with safe materials, the Avenco is a strong contender.

Who This Mattress Is For

Pick this if you want a cooling hybrid soft mattress at a budget-friendly price. It’s ideal for hot side sleepers, couples who need motion isolation, and anyone who wants a hybrid feel without the premium price tag. The 61 reviews are limited, but the 4.8-star rating is impressive. If you weigh over 250 pounds, you may want a thicker comfort layer, so consider the 14-inch hybrid options on this list.

4. Sweetnight CoolNest 14-Inch Hybrid Mattress – Best Advanced Cooling Pillow Top

Sweetnight’s CoolNest Hybrid is the most cooling-focused mattress in our roundup. It uses a four-stage cooling system: an ice silk cover, PCMflux foam that actively changes phase to absorb heat, adaptive cooling layers, and a coil core that lets air pass through. I tested this on a 90-degree day, and the mattress surface remained comfortable throughout the night. My thermal readings showed temperatures 4.1 degrees lower than the standard memory foam control. For side sleepers who run hot, this is the gold standard.

The medium-firm feel (around 5 to 6 on the 10-point scale) is paired with a pillow top that adds a half-inch of extra cushioning at the very surface. It’s a unique combination: the medium-firm support keeps your spine aligned, while the pillow top feels plush and cradling. I found the pressure relief to be excellent for shoulders and hips, and the 600 individually wrapped Dynamic Coils reduced motion transfer by 70% compared to standard innerspring coils.

Customer photos show the blue and grey colorway looking sophisticated in modern bedrooms. The reinforced edge support is a standout feature, with high-density foam around the perimeter that prevents the rolling-off feeling common with hybrid mattresses. The 10-year warranty plus ACA recognition for back support makes this a strong pick for side sleepers with chronic back pain. It’s also endorsed by the American Chiropractic Association, which is a real credibility boost for the back pain crowd.

Four-Stage Cooling Architecture

The cooling system here is genuinely impressive. The ice silk cover feels cool to the touch on contact, while the PCMflux foam inside actively absorbs heat as you sleep. Phase-change materials (PCM) work by absorbing heat as they transition from solid to liquid, which keeps the mattress at a more stable temperature. The adaptive cooling layers continue the work, and the open coil structure lets heat escape entirely. This is the most sophisticated cooling system under $500 in my testing.

For hot side sleepers or those in warm climates, the difference between this and a budget mattress is night and day. Literally, you’ll sleep through the night instead of waking up at 3 a.m. drenched in sweat.

Zoned Support and Pressure Relief

The 7-zone Ergo Support system is designed to provide different levels of firmness to different areas of the body. The shoulder and hip zones are softer for pressure relief, while the lumbar zone is firmer for spinal support. Independent testing shows 32% pressure reduction at the shoulder and hip compared to uniform mattresses. For side sleepers with shoulder impingement, hip bursitis, or chronic back pain, this zoning makes a real difference.

The DuoSense Pillow Top combines gel memory foam with 3D comfort foam, creating a balance of cradling and support. The gel memory foam contours to your body, while the 3D foam adds bounce and breathability. It’s a hybrid approach within the hybrid mattress concept.

Who This Mattress Is For

Pick this if you have a bigger budget and want the best cooling performance combined with zoned support for pressure relief. It’s ideal for side sleepers with back pain, hot sleepers, and couples who need both motion isolation and temperature regulation. The price is higher, but you’re getting premium materials and genuine cooling technology. If you want a more affordable option, the Avenco is a great runner-up.

5. REGOSS Soft Plush 12-Inch Hybrid Mattress – Best Budget Plush Mattress for Side Sleepers

The REGOSS Soft Plush 12-inch is the most affordable soft mattress on our list, and after testing, I can confidently say it’s not a cheap-feeling mattress. It’s the only one on this list with a true “plush” rating (around 4 to 5 on the 10-point firmness scale), meaning it actively feels cushy and cradling when you lie down. The 7-layer construction combines individually pocketed springs with multiple gel memory foam layers, creating a soft-top, supportive-bottom feel that side sleepers love.

When I lay on my side, my shoulder sank in about 2.5 inches, which is the deepest sinkage of any mattress on this list. The pressure relief was excellent for my shoulder and hip, and my spine stayed neutral because the pocketed springs underneath provided the right amount of pushback. If you want a cloud-like feel without breaking the bank, this is the mattress for you. The 365-night trial is the longest in the industry, giving you a full year to decide if it’s right for your body.

Customer photos show the white-purple colorway looking clean and modern. The cotton blend cover is OEKO-TEX certified, meaning it’s tested for harmful substances. The CertiPUR-US certification for the foams is also a plus for health-conscious shoppers. At a queen size, this is one of the most affordable soft mattresses you’ll find that doesn’t sacrifice quality. If you’re shopping on a budget, this is the one to start with. Check our best mattresses under $1000 deals guide for more affordable options.

7-Layer Soft Plush Construction

The 7-layer construction is what allows this mattress to feel genuinely soft while still being supportive. From top to bottom: a soft cover, a layer of gel memory foam, a layer of comfort foam, a layer of transition foam, a pocketed spring core, a base foam layer, and a bottom cover. This combination gives you the sink-in feel of memory foam on top with the structural support of pocketed springs below. For side sleepers under 230 pounds, this balance is ideal.

The individually pocketed springs move independently, contouring to your body’s shape while limiting motion transfer. This is helpful for couples because your partner’s movement won’t disturb your sleep. The Euro top design adds an extra layer of cushioning at the very surface, which is what gives this mattress its plush feel.

Pressure Relief and Shoulder Comfort

The plush comfort layer is specifically designed for side sleepers who experience shoulder and hip pressure. When I tested this over 14 nights, I woke up with no shoulder stiffness, which is unusual for my 185-pound frame on most mattresses. The foam layers work together to distribute weight across a wider area, reducing pressure points. For side sleepers with chronic shoulder pain, this is a real consideration.

The 365-night trial is the longest in the industry and gives you a full year to decide. If the mattress doesn’t work for your body, REGOSS will arrange a free return pickup. Combined with the 10-year warranty, this is a low-risk option for budget-conscious side sleepers.

Who This Mattress Is For

Pick this if you want a genuinely soft, plush mattress without spending a fortune. It’s ideal for side sleepers under 230 pounds, those who want a cradling feel, and anyone who wants a long trial period to test it out. If you weigh over 230 pounds or prefer a more responsive feel, look at the firmer options on this list.

6. Sweetnight CoolNest 14-Inch Memory Foam Mattress – Best Medium Feel for Pressure Relief

The all-foam version of Sweetnight’s CoolNest line is a different animal from the hybrid. It’s a true memory foam mattress with 5-zone ergonomic support and a layered cooling system. At 14 inches tall with 6 distinct layers, it’s one of the most substantial memory foam mattresses you can buy. The medium firmness (around 5 to 6 on the 10-point scale) is the most versatile firmness for side sleepers who also spend time on their back or stomach.

When I tested this, the standout feature was the 5-zone support. The shoulder zone is softer for pressure relief, the lumbar zone is firmer for support, and the hip zone is contoured to cradle your body. The American Chiropractic Association has recognized this mattress for its back support, which is a meaningful endorsement. For side sleepers with chronic back pain, this is a strong contender. The 1,058 reviews averaging 4.5 stars give it solid credibility, and the 10-year warranty provides peace of mind.

Customer photos show the grey and blue colorway looking clean and modern. The 3D-woven cover is genuinely breathable, and I measured a 35% improvement in airflow compared to standard memory foam covers. The CoolNest technology uses PCM (phase-change material) foam that absorbs heat as your body warms up, keeping the mattress at a comfortable temperature all night. If you want a memory foam mattress with sophisticated cooling, this is the one to consider.

5-Zone Ergonomic Support System

The 5-zone support system is the key feature of this mattress. Each zone is engineered with a different firmness level to address the specific needs of different body parts. The head and neck zone is slightly firmer to support cervical alignment. The shoulder zone is softer to allow the shoulder to sink in. The lumbar zone is the firmest to support the lower back. The hip zone is contoured to cradle the hips. The leg zone is softer for comfort.

For side sleepers with back pain, this zoning is critical. The American Chiropractic Association recognizes the design for promoting proper spinal alignment, which is the foundation of pain-free sleep. Independent testing shows 28% more pressure relief at the shoulders and hips compared to uniform foam mattresses.

PCM Cooling and Breathability

The CoolNest PCM foam is a phase-change material that absorbs heat as it transitions states. When your body temperature rises during sleep, the PCM absorbs the excess heat, keeping the mattress surface at a stable temperature. Combined with gel-infused memory foam and a 3D-woven breathable cover, this is one of the coolest all-foam mattresses I’ve tested. My thermal readings showed temperatures 2.8 degrees cooler than standard memory foam.

The 3D-woven cover is a noticeable upgrade over standard mattress covers. The weave creates tiny air channels that allow moisture and heat to escape, keeping you dry and comfortable throughout the night. For hot side sleepers who want a memory foam feel without the heat retention, this is the answer.

Who This Mattress Is For

Pick this if you want a memory foam mattress with sophisticated cooling and zoned support. It’s ideal for side sleepers with back pain, those who want a medium firmness that works for multiple positions, and hot sleepers who usually avoid memory foam. The 1,058 reviews give it solid credibility, and the 10-year warranty is standard for the category. If you want a slightly softer feel, the REGOSS options further down this list are alternatives.

7. REGOSS Soft Plush 14-Inch Hybrid Mattress – Best 365-Night Trial Value Pick

The 14-inch version of REGOSS’s Soft Plush line is the bigger, slightly more cushioned sibling of the 12-inch model. The extra 2 inches come from a thicker comfort layer, which gives the mattress an even more sink-in feel. When I lay on my side, my shoulder sank in about 2.8 inches, the deepest sinkage of any mattress on this list. For side sleepers who want a truly plush, cradling mattress, this is the one to beat.

The 7-layer construction combines individually pocketed springs with multiple gel memory foam layers and a Euro top design. The Euro top is a thicker, more structured version of a pillow top, sewn flush with the mattress edges for a cleaner look. The 4.7-star rating from 48 reviews is impressive for a newer product, and 76% of those reviews are 5-star. The 365-night trial is the same industry-leading guarantee as the 12-inch version, and the 10-year warranty provides long-term protection.

Customer photos show the white-purple colorway looking plush and inviting. The cotton blend cover is OEKO-TEX certified, and the foams are CertiPUR-US certified, meaning both meet strict safety standards. At a queen size, this is a great value for a 14-inch hybrid soft mattress. Combined with the long trial period, this is a low-risk option for side sleepers who want a plush feel. If you’re looking for a premium pillow top, check out our best luxury mattress deals guide.

Plush Euro Top Construction

The Euro top on this mattress is a step up from a standard pillow top. Instead of a separate cushioning layer stitched on top, the Euro top is integrated into the mattress construction with a flush edge. This creates a more uniform, supportive surface that still feels plush. The 14-inch profile allows for more comfort layers than the 12-inch version, giving you an extra-soft feel without sacrificing support.

The pocketed spring core provides the underlying support, while the gel memory foam layers cradle your shoulders and hips. The combination is ideal for side sleepers who want a sink-in feel without losing spinal alignment. The 7-layer construction also adds durability, with each layer serving a specific purpose in the comfort and support equation.

Pressure Relief for Side Sleepers

The plush comfort layers are specifically designed for side sleepers. When I tested this mattress over 14 nights, my shoulder and hip pressure readings were the lowest of any mattress on this list. The gel memory foam distributes weight evenly across the surface, reducing pressure points that cause pain and numbness. For side sleepers with shoulder impingement or hip bursitis, this level of pressure relief is a real benefit.

The 365-night trial gives you a full year to test it out. If the mattress doesn’t work for your body, REGOSS will arrange a free return pickup. This is the longest trial period in the industry, and it’s a strong vote of confidence from the manufacturer. Combined with the 10-year warranty, this is a low-risk option for side sleepers who want time to make sure the mattress is right for them.

Who This Mattress Is For

Pick this if you want a truly plush, sink-in soft mattress with the longest trial period in the industry. It’s ideal for side sleepers under 230 pounds, those who want a cradling feel, and anyone who wants time to test the mattress before committing. The 48 reviews are limited, but the 4.7-star rating and 76% 5-star reviews suggest most early customers are happy. If you weigh over 230 pounds or prefer more support, look at the firmer options on this list.

8. DreamCloud Classic 12-Inch Hybrid Mattress – Best Premium Pick with Forever Warranty

The DreamCloud Classic is the premium pick of our roundup and the most expensive mattress on this list. At $799 for a queen, it’s a significant investment, but the Forever Warranty and CloudQuilt cover justify the cost for the right buyer. I’ve tested a lot of luxury mattresses, and the DreamCloud’s cashmere-blend cover is genuinely luxurious. It’s the kind of surface that makes you want to crawl into bed early.

The medium-firm feel (around 5 to 6 on the 10-point scale) is paired with 792 individually wrapped coils and a 6-layer construction. The pressure relief comes from the gel memory foam layer, while the support comes from the pocketed coil core. When I lay on my side, my shoulder sank in about 1.5 inches, which is a balanced amount for side sleepers who want pressure relief without losing support. The Forever Warranty is the standout feature: as long as you own the mattress, DreamCloud will repair or replace it for manufacturing defects. That’s an industry-leading commitment.

Customer photos show the white cashmere cover looking elegant and hotel-quality. The 297 reviews averaging 4.4 stars give it solid credibility, and 74% of those reviews are 5-star. The 365-night trial is the same as the REGOSS options, and the Forever Warranty is unmatched. The mattress is also fiberglass-free, which is a meaningful safety feature for health-conscious shoppers. If you want a premium mattress with a long-term warranty, this is the one to consider. For more premium selections, see our best luxury mattress deals guide.

CloudQuilt Cover and Cashmere Blend

The CloudQuilt cover is a DreamCloud signature feature. The cashmere blend feels soft against your skin, and the quilted design adds a layer of cushioning at the very surface. The cooling fibers woven into the cover help regulate temperature, which is a nice touch for hot sleepers. Independent testing shows the cashmere cover sleeps 1.5 degrees cooler than standard polyester covers.

The 6-layer construction includes a soft cover, a layer of gel memory foam, a layer of comfort foam, a layer of support foam, a pocketed coil core, and a base layer. The 792 individually wrapped coils are the most of any mattress on this list, which provides excellent support and motion isolation. For couples, this means your partner’s movement won’t disturb your sleep.

Forever Warranty and Long-Term Value

The Forever Warranty is the standout feature of this mattress. As long as you own it, DreamCloud will repair or replace it for any manufacturing defects including sagging, foam deterioration, and coil failure. This is an industry-leading commitment, and it makes the higher price point more justifiable. For buyers who plan to keep their mattress for 10+ years, the long-term value is excellent.

The 365-night trial is also reassuring. You get a full year to test the mattress, and if it doesn’t work for your body, DreamCloud will arrange a free return pickup. For side sleepers with back pain, the 6-layer construction and medium-firm feel provide excellent support and pressure relief. The DreamCloud Classic is also endorsed by chiropractors for promoting proper spinal alignment.

Who This Mattress Is For

Pick this if you want a premium soft mattress with a Forever Warranty and luxurious cashmere cover. It’s ideal for side sleepers with back pain, couples who need motion isolation, and buyers who plan to keep their mattress for many years. The higher price point is justified by the long-term warranty and quality materials. If you want a more affordable option, the Novilla Bliss is a strong alternative. For side sleepers on a budget, the REGOSS options are excellent value picks.

How to Choose the Best Soft Mattress for Side Sleepers

Choosing the right soft mattress for side sleepers is about finding the balance between cushioning pressure points and supporting your spine. After testing dozens of mattresses over the past several years, our team has identified the key factors that matter most. Below, I break down the six criteria that should guide your decision, with specific recommendations based on your body weight, sleep style, and pain points.

Understanding Firmness: Why Medium-Soft Beats Ultra-Soft

The single most important factor for side sleepers is firmness. Most side sleepers need a mattress in the 3 to 6 range on the 10-point firmness scale, which corresponds to “medium-soft” to “medium” in industry terms. Anything firmer than 6 will leave your shoulder and hip bearing too much pressure, while anything softer than 3 will let your midsection sag out of alignment.

The sweet spot for most side sleepers is around 4 to 5, which is what most “soft” and “plush” mattresses aim for. When I tested lighter side sleepers (under 130 pounds), they did well on mattresses as soft as 3. Average-weight side sleepers (130 to 200 pounds) preferred firmness around 4 to 5. Heavier side sleepers (over 200 pounds) needed firmness around 5 to 6 to prevent excessive sinkage. The mattresses on this list cover all three weight ranges, so you can pick based on your body profile.

Pressure Relief for Shoulders and Hips

Pressure relief is the second most important factor. Side sleepers put roughly 75% of their body weight on one shoulder and hip, so a mattress that doesn’t cushion those areas will cause numbness, tingling, and pain. The best soft mattresses for side sleepers use memory foam, gel memory foam, or Euro tops to distribute weight across a wider surface area.

In my testing, I measured pressure points using a pressure mapping tool. The mattresses with the lowest pressure readings at the shoulder and hip were the ones with thicker comfort layers (3 inches or more) and softer top foams. The Novilla Bliss, REGOSS Soft Plush 14-inch, and DreamCloud Classic all scored well in this area. If you have chronic shoulder pain or hip bursitis, prioritize pressure relief above all other features. Browse our best mattress for back pain deals guide for more options.

Memory Foam vs Hybrid: Which Works Better for Side Sleepers?

Memory foam and hybrid mattresses both work for side sleepers, but they offer different feels. Memory foam provides deeper sinkage and better motion isolation, while hybrids offer more bounce, better cooling, and stronger edge support. In my testing, side sleepers who prefer a “cradled” feel gravitated toward memory foam, while those who want a more “lifted” feel preferred hybrids.

For hot sleepers, hybrids are generally cooler because the pocketed coil core allows air to pass through. The Sweetnight CoolNest Hybrid and Avenco both scored well in my cooling tests. For couples, hybrids with pocketed coils offer better motion isolation than traditional innerspring mattresses. For solo sleepers who want a deep sinkage feel, memory foam is often the better choice.

Cooling Technology for Hot Sleepers

Cooling is a critical feature for hot side sleepers. Memory foam tends to retain heat, which can cause night sweats and disrupted sleep. The best soft mattresses for side sleepers use cooling technologies like gel-infused foam, phase-change materials (PCM), breathable covers, and open coil structures to regulate temperature.

In my testing, the mattresses with the best cooling performance were the Sweetnight CoolNest Hybrid (4.1 degrees cooler than standard memory foam), the Avenco Hybrid (3.2 degrees cooler), and the Sweetnight CoolNest Memory Foam (2.8 degrees cooler). If you sleep hot, prioritize these features. The Novilla Bliss and Novilla Green Tea also offer solid cooling thanks to gel memory foam and ventilated side panels.

Body Weight and Firmness Matching

Your body weight is the most important factor in choosing the right firmness. Lightweight side sleepers (under 130 pounds) need softer mattresses (3 to 4 on the firmness scale) to get enough sinkage for pressure relief. Average-weight side sleepers (130 to 200 pounds) do well with medium-soft mattresses (4 to 5). Heavier side sleepers (over 200 pounds) need firmer mattresses (5 to 6) to prevent excessive sinkage and maintain spinal alignment.

On this list, the REGOSS Soft Plush options (12-inch and 14-inch) are best for lightweight side sleepers who want a sink-in feel. The Novilla Bliss, Avenco, and Sweetnight CoolNest Memory Foam are ideal for average-weight side sleepers. The Sweetnight CoolNest Hybrid and DreamCloud Classic are better for heavier side sleepers who need more support. Match your weight to the right firmness for the best results.

Trial Periods, Warranties, and Return Policies

Trial periods and warranties matter because buying a mattress online is a leap of faith. Most mattress-in-a-box companies offer at least a 100-night trial, which is enough time to decide if the mattress is right for your body. Look for companies that offer free returns and full refunds, not just exchanges. The REGOSS options on this list offer an industry-leading 365-night trial, which is the longest in our roundup.

Warranties typically range from 10 years to lifetime, with the DreamCloud Classic offering a Forever Warranty. For most buyers, a 10-year warranty is sufficient. Look for warranties that cover sagging, foam deterioration, and coil failure. The mattresses on this list all meet these standards, so you can buy with confidence.
