Best Mattress for Side Sleepers 2026: 5 Ranked Picks

Side sleeping puts nearly all of your body weight on two small areas: the shoulder and the hip. The best mattress for side sleepers is one that lets those points settle in while the waist stays supported, and for most side sleepers that points to a cushioned surface rather than a hard one. Our pick is the Saatva Classic in Plush Soft, an innerspring with a 3 inch Euro pillow top, and second on this list is the PlushBeds Heavenly Plush Luxury Hybrid, a foam and coil build offered in three heights.

If you sleep almost exclusively on your side and want a body-hugging top with a firmness choice inside one model, buy the Saatva Classic in Plush Soft. If you want deep cushion in a luxury hybrid with a long return window, the PlushBeds Heavenly Plush Luxury Hybrid is the better fit. A side sleeper who also spends the night on their back or stomach should look at the middle comfort level instead of the softest one, and a shopper who wants a single medium feel in an all-foam or hybrid build should read on before ordering.

Who is the Saatva Classic Plush Soft for?

The Saatva Classic Plush Soft is built for people who fall asleep on their side and want the surface to give at the shoulder and hip without letting the middle of the body sag. Saatva rates it 3 out of 10 for firmness on its own scale, where 1 is the softest and 10 the firmest, and describes the feel as soft and cushiony thanks to the extra padding on top, body-hugging to relieve pressure points. It is also aimed at lighter-weight people who often find mattresses too firm.

If you share a bed with a back or stomach sleeper, the same Classic model is available in Luxury Firm (5-7/10) and Firm (8/10), so two people can order different comfort levels of one model. Side sleepers who also roll onto their back during the night should compare Plush Soft against Luxury Firm before ordering. A surface that feels deeply cushioned at the shoulder may feel less supportive once you turn onto your back, and Luxury Firm is Saatva’s most popular comfort level, described as a balance of cushioning and uplifting support suitable for all sleep positions. The choice is a preference question, not a rule.

There is also a practical reading of the firmness labels. Plush Soft at 3 out of 10 sits at the soft end of Saatva’s own scale, while Luxury Firm spans 5 to 7 and Firm sits at 8. Those numbers are Saatva’s own ratings for its own comfort levels, and they are useful for ordering within one brand rather than for comparing across brands. If you have slept on a firm hotel bed and liked it, Luxury Firm is the level Saatva designed to replicate that feel. If you have ever woken with a sore shoulder on a hard surface, Plush Soft is the level built for that complaint.

What should a side sleeper look for in a mattress?

Three things matter together: the feel of the surface, support through the middle of the body, and how easily you change position at night. A mattress that feels plush at the shoulder can still feel wrong if the waist is unsupported, and a firm surface that seems stable at first may press too hard on the shoulder for your preference. Notice pressure and support as two separate things. A softer top can feel cushioned while the complete mattress still needs to feel supportive to you.

Compare your usual positions. If you spend part of the night on your back or stomach, a mattress chosen only for side sleeping may not suit the rest of the night. Check the pillow and frame as well: head height, mattress height and the support surface all change the overall setup. No firmness label is a standardized measurement shared across every manufacturer, so use brand labels to narrow the options and then evaluate the actual product under the seller’s stated terms.

It also helps to think about the order in which you fall asleep. Many side sleepers start on one side and then settle onto the back for the second half of the night. A mattress chosen only for the first position may feel different an hour later, which is why Saatva describes Luxury Firm as suitable for all sleep positions while Plush Soft is aimed specifically at side sleepers and lighter weight sleepers. If you know you almost never leave your side, the softer level is the natural choice. If you move between positions, the middle level gives you more room to be right.

If you already know you prefer foam over springs, our best memory foam mattresses covers that route, and shoppers who want a coil build with a cushioned top can start from our best hybrid mattresses.

The ranked list: 5 mattresses for side sleepers in 2026

#1 Saatva Classic

Who it suits: side sleepers, and lighter-weight sleepers, who want a cushioned innerspring with a body-hugging top and a firmness choice inside one model. The Classic carries a 3 inch Euro pillow top that Saatva says comes standard for cushioned comfort and pressure relief inspired by mattresses found in high-end luxury hotels. Beneath it sits a dual-coil design made of triple-tempered recycled carbon steel, with over 1,000 coils in full size and up, which gives the surface a responsive, contouring feel rather than a stuck-in-place one.

Patented Lumbar Zone Technology runs through the middle of the mattress, and Saatva states it helps ensure healthy spinal alignment in any sleep position. The cover is a soft, breathable blend that includes organic cotton and is treated with Guardin botanical antimicrobial treatment. The model comes in two heights, 11.5 inches and 14.5 inches, and in three comfort levels: Plush Soft (3/10), Luxury Firm (5-7/10) and Firm (8/10). Saatva lists the Classic with a 365-night home trial, free white-glove delivery with in-room setup and old-mattress removal, and a lifetime warranty for the original purchaser.

Honest drawback: Plush Soft is a preference-led choice, and a side sleeper who also sleeps on their back may find the softer level less supportive once they turn over, which is why Saatva also offers Luxury Firm in the same model.

#2 PlushBeds Heavenly Plush Luxury Hybrid

Who it suits: side sleepers who want deep pressure relief in a luxury hybrid, with three firmness heights to choose from and a long return window. The Heavenly Plush Luxury Hybrid is offered in three heights: 12 inch Firm, 14 inch Cushion-Firm and 16 inch Ultra-Plush, across Twin, Twin XL, Full, Queen, King, Cal King and Split King. PlushBeds lists a 365 night return policy, a 365 night comfort exchange and a Forever Warranty. Free US shipping applies excluding Alaska and Hawaii.

The brand describes the mattress as built for deep pressure relief, cooling comfort and elegant support, which is the profile a side sleeper is shopping for at the shoulder and hip.

Honest drawback: the Ultra-Plush height is the deepest cushion in this model, and a side sleeper who prefers a firmer surface has to move down to the 12 inch Firm version instead.

#3 Puffy Mattresses

Who it suits: side sleepers who want a body-adapting memory foam build with a soft breathable knit cover, in a medium-firm feel. The Puffy Cloud Mattress is listed as a 6 layer memory foam model with a medium-firm feel, and the Puffy Lux Hybrid steps up to 8 layers with a medium-plush feel combining memory foam and wrapped coils. Puffy lists a 365 night sleep trial, a lifetime warranty and free shipping with free returns.

Sizes run Twin through Split King, including Split Head Queen and Split Head King.

Honest drawback: the Cloud model is a single medium-firm feel, so a side sleeper who wants a deeply soft surface has to move up to the Lux Hybrid rather than choosing a softer version of the same model.

#4 Sweetnight Coolnest

Who it suits: side sleepers who want a cooling build in a choice of thicknesses, with a zoned support layer in the taller versions. The Sweetnight Coolnest is sold as a memory foam mattress and as a hybrid, each in 12, 14 and 16 inch thicknesses, across Twin, Full, Queen, King and CLK sizes. Sweetnight lists a 100-night trial, free U.S. shipping and a 10-year warranty.

The memory foam model carries a 5-Zone Ergo Support Design with 9 comfort bars, a 3D weaving Coolnest cover, PCMflux high resilience foam and gel-infused memory foam, all CertiPUR-US certified with fabric passing STANDARD 100 by OEKO-TEX. The hybrid version lists a DuoSense pillow top, zoned support foam on the 14 and 16 inch models, and Innovative Dynamic Coil technology with high-compression pocket coils and a reinforced edge. Sweetnight states the Coolnest system feels up to 8 degrees cooler.

Honest drawback: the 16 inch thickness on the memory foam model is marked sold out on the product page, so a side sleeper who wants the deepest version of that build has to choose the 14 inch instead.

#5 Serta Perfect Sleeper X Hybrid Level Two Plush

Who it suits: side sleepers who want a plush hybrid with targeted zones and a micro coil layer, in a smooth-top build. The Serta Perfect Sleeper X Hybrid Level Two Plush is described as made for side sleepers, with a Plush feel and a 5 ZoneActive design combining responsive coils and contouring memory foam. It carries 1 inch of Perfect Conform memory foam, a layer of micro coils, and cooling technology with graphite-infused memory foam.

Serta lists a 100-night trial, free shipping and returns and a 10-year limited warranty. The Level Two model is offered in Twin XL, Full, Queen, King and Cal King, and the brand states its foam is CertiPUR-US certified. Serta also describes Cool Twist gel memory foam as enhancing airflow and heat dissipation, and EverCool Supreme memory foam as a higher-density foam that gently cradles the body.

Honest drawback: the Level Two Plush is a single plush feel, so a couple who disagree on firmness has to compare the medium firm version of the same model rather than ordering two feels of this one.

Who should buy which mattress for side sleeping?

Buy the Saatva Classic in Plush Soft if you sleep on your side nearly every night, want a 3 inch Euro pillow top that gives at the shoulder and hip, and like the idea of choosing between three comfort levels and two heights inside one model. Saatva rates Plush Soft at 3 out of 10 on its own scale, where 1 is the softest and 10 the firmest, and pairs it with a 365-night home trial, free white-glove delivery with old-mattress removal, and a lifetime warranty. Side sleepers who want a single medium-firm memory foam build with a 365 night trial and lifetime warranty should read the Puffy entry, while hot sleepers who want a zoned support layer in a 100-night trial should look at the Sweetnight Coolnest. Shoppers who want a plush hybrid with 5 zones and micro coils, backed by a 100-night trial and 10-year limited warranty, land on the Serta Perfect Sleeper X Hybrid Level Two Plush.

If you want a natural materials route for this search, our best latex mattresses and best organic mattresses cover those builds.

What does the Saatva Classic cost and what comes with it?

The model ships with free white-glove delivery that includes in-room delivery and setup, plus removal of your old mattress at no additional cost when you check the free mattress removal box at checkout. Every Saatva mattress comes with a 365-night home trial and a lifetime warranty for the original purchaser.

The Classic sits on a foundation or box spring, a standard bed frame with a foundation, a platform bed frame with slats at least 3 inches wide and spaced less than 4 inches apart, or an adjustable base in the 11.5 inch height only. Saatva lists the foams as CertiPUR-US certified and the mattress as GREENGUARD Gold certified, and states the model is endorsed by the American Chiropractic Association. If you are pairing the mattress with a base, our Saatva adjustable base review walks through that option, and the wider accessory range sits in our Saatva accessories hub.

Who should NOT buy the Saatva Classic?

Skip the Plush Soft comfort level if you are a dedicated stomach sleeper or a heavier body type in the 250 to 300 pound range, since Saatva points those sleepers to the Firm (8/10) level instead, which it describes as a floating on top feel. Skip the Classic altogether if you want a single medium feel with no firmness decision to make, because the model asks you to pick one of three comfort levels and one of two heights before you order. Side sleepers in that position tend to prefer the Puffy Cloud’s medium-firm memory foam build or the Serta Level Two Plush, both of which arrive in one feel.

Also skip the Classic if you need a mattress that arrives by standard parcel shipping, since Saatva delivers it by white-glove service with in-room setup rather than a box at the door. That service is the reason old-mattress removal is included, and it is a benefit rather than a drawback for most buyers, but it does mean the delivery is scheduled rather than left on a porch.

What is our Saatva alternative for side sleepers?

The Saatva Classic is our first recommendation for side sleepers, and the PlushBeds Heavenly Plush Luxury Hybrid is the alternative we would point to for a shopper who wants a different build. Both carry a 365 night return window and a long warranty, but they differ in one real way: the Classic gives you three comfort levels and two heights inside one model, while the Heavenly Plush Luxury Hybrid gives you three heights of one build, at 12 inch Firm, 14 inch Cushion-Firm and 16 inch Ultra-Plush. A couple who disagree on firmness can order two comfort levels of the Classic; a shopper who wants to choose cushion depth instead picks a height on the PlushBeds.

The PlushBeds also lists a 365 night comfort exchange alongside its 365 night return policy, which gives side sleepers a second window to change their mind about the feel after delivery. The Saatva Classic counters with free white-glove delivery and old-mattress removal, which the PlushBeds page does not include in its shipping terms. Choose the Classic if delivery setup and removal matter to you, and the Heavenly Plush Luxury Hybrid if a comfort exchange after the first month matters more.

Frequently asked questions

Is a soft mattress better for side sleepers?

A softer surface generally lets the shoulder and hip settle in, which is why Saatva rates its Plush Soft level at 3 out of 10 on its own scale and describes it as body-hugging to relieve pressure points, aimed at side sleepers who need extra pressure relief on the hips and shoulders. Soft is a preference, not a rule: a side sleeper who also spends the night on their back may find the softer level less supportive once they turn over, which is why Saatva also offers Luxury Firm at 5-7/10 in the same model.

What firmness should a side sleeper choose?

Use the brand’s own scale rather than a universal number, since no firmness label is standardized across manufacturers. On Saatva’s scale, where 1 is the softest and 10 the firmest, Plush Soft sits at 3, Luxury Firm spans 5 to 7 and Firm sits at 8, and Saatva describes Luxury Firm as a balance of cushioning and uplifting support suitable for all sleep positions. Side sleepers who never leave their side tend to prefer the softer level, while combination sleepers often land in the middle.

How long can you try a mattress before returning it?

Trial lengths differ by brand on this list: Saatva and PlushBeds each list 365 nights, Puffy lists 365 nights, while Sweetnight and Serta each list 100 nights. PlushBeds adds a 365 night comfort exchange on top of its return policy, so a side sleeper who picks the wrong height has a second window to change the feel. The trial is the practical test for a position-specific choice like side sleeping, since pressure at the shoulder and hip only shows up over full nights.

Can a side sleeper share a bed with a stomach sleeper?

Yes, if the mattress offers more than one feel. The Saatva Classic comes in Plush Soft (3/10), Luxury Firm (5-7/10) and Firm (8/10), so two people can order different comfort levels of one model, and Saatva describes Luxury Firm as ideal for couples with different firmness preferences and sleep styles. On this list only the Saatva offers that choice inside a single model, which is why it leads for mixed-position households.

Does mattress height matter for side sleepers?

Height changes head position and pillow choice more than it changes the feel of the surface. The Saatva Classic comes in 11.5 inches and 14.5 inches, the PlushBeds Heavenly Plush Luxury Hybrid in 12, 14 and 16 inches, and the Sweetnight Coolnest in 12, 14 and 16 inches, so a side sleeper with a thick pillow or an adjustable base can match the setup. The 11.5 inch Saatva Classic is the height that pairs with an adjustable base.

What is the best mattress for side sleepers in 2026?

The Saatva Classic in Plush Soft is our number one pick for side sleepers in 2026, with the PlushBeds Heavenly Plush Luxury Hybrid in second place. The Classic carries a 3 inch Euro pillow top, a dual-coil design with over 1,000 coils in full size and up, three comfort levels and two heights, a 365-night home trial and a lifetime warranty. The Heavenly Plush Luxury Hybrid answers with three heights, a 365 night return policy and a Forever Warranty.

Verdict: the Saatva Classic in Plush Soft is the mattress to buy for side sleepers who want a cushioned innerspring with a firmness choice inside one model, backed by a 365-night home trial, free white-glove delivery with old-mattress removal and a lifetime warranty. Side sleepers who want a foam and coil hybrid in three heights with a comfort exchange should take the PlushBeds Heavenly Plush Luxury Hybrid instead.
