Most adults sleep on their sides at least some of the time, and there's no shortage of mattresses that manufacturers claim are designed for this purpose. The best mattresses for side sleeping offer strong pressure relief, since more weight is concentrated on smaller areas of your arm and shoulder when you sleep on your side. That means you'll want a mattress with good body conformity, so you can sink in sufficiently and avoid uncomfortable pressure points. Solid support is also important, so your hips don't sink in overly far and your spine stays aligned. Medium and Medium-Plush mattresses are often best suited for side sleeping, though it depends on your weight; firmer models often perform better for heavier individuals.
We've tested over 55 mattresses, and below are our recommendations for the best mattresses for side sleepers. Our picks include options for people in a range of weight categories, and we've also considered other important aspects like cooling to help you sleep comfortably, motion dissipation so you can sleep peacefully with a partner, and longevity so your mattress maintains its performance for as long as possible.

We've tested over 55 mattresses. We purchase each unit independently from major retailers, just like you, to keep our reviews free of manufacturer influence. Each mattress undergoes the same tests to measure objective data on characteristics like firmness, cooling, and motion isolation, so you can easily compare results. Since we buy all our mattresses, we can tear them down layer by layer and isolate the mechanical properties of every component: quilted tops, foams, coils, and any special materials.

Best Mattress For Side Sleepers
Side Sleeping8.3Light Weight7.6Average Weight8.4Heavy Weight8.9Firmness LevelMedium (47 Pa/mm)Longevity5.3Motion Dissipation8.5Cooling8.9See all our test resultsResponsiveness5.0The Casper Snow is the best mattress for side sleepers we've tested. It's a great choice for side sleeping regardless of your weight, and is also very versatile, offering solid support for combination sleepers, excellent cooling for hot sleepers, and strong motion dissipation for couples. This Medium mattress lets your shoulders and arms sink in thanks to its soft memory foam comfort layers, which relieve pressure and help make it a comfortable option for side sleeping. It performs best for average-weight and heavier people, but regardless of your weight, it'll relieve pressure effectively. Support is also solid enough regardless of your weight, which helps ensure you sink in evenly, and your spine stays aligned throughout the night. It also offers excellent cooling both when you get into bed and throughout the night, and its amazing motion dissipation means you can sleep peacefully with a partner.
However, keep in mind that its soft, slow-moving memory foam comfort layers give it an enveloping feel, so you feel like you are sleeping 'in' rather than 'on' the mattress. It's also not very responsive, which makes it feel harder to move around on and might leave you feeling constricted. If you prefer to sleep 'on' and not 'in' your mattress, our next recommendation, the Helix Midnight Luxe 2025, is a better choice. Finally, note that the Casper's comfort layers use low-quality memory foam, so it is likely to form permanent indentations sooner than mattresses that use higher-quality foams.

Best Upper Mid-Range Mattress For Side Sleepers
Side Sleeping8.2Light Weight7.1Average Weight8.5Heavy Weight8.9Firmness LevelMedium (44 Pa/mm)Longevity6.8Motion Dissipation8.2Cooling8.2See all our test resultsResponsiveness8.2If the Casper Snow's plush, enveloping sleeping surface sounds like your worst nightmare, we recommend checking out the upper mid-range Helix Midnight Luxe 2025 instead. Like the Casper, it's a Medium hybrid mattress best suited for average-weight and heavier side sleepers and also offers good cooling for hot sleepers. This mattress's plush quilted top and memory foam upper comfort layer let you sink in and contour around you quite closely, relieving pressure on your arm and shoulder. However, because of the much more responsive sleeping surface, you don't feel tightly hugged or stuck in place, and it's easier to change sleeping positions than the Casper. It also offers great cooling, so it shouldn't make you feel overheated, even if you're usually a hot sleeper.
The mattress's sides are reinforced with firmer coils and are difficult to compress, allowing you to comfortably sit or sleep near the edge of the bed. But while its motion isolation performance is good overall, it's not as good as the Casper's, and larger movements can make the mattress bounce or wobble for a moment. As a result, this mattress isn't for you if you sleep with a partner who tosses and turns in their sleep, and you're easily awoken. Finally, it uses more durable foam than the Casper, but lower-quality foam in the quilted layer may still lead to permanent indentations sooner than mattresses with high-quality, dense foams.

Best Mid-Range Mattress For Side Sleepers
Side Sleeping7.9Light Weight7.0Average Weight8.2Heavy Weight8.5Firmness LevelMedium (46 Pa/mm)Longevity6.3Motion Dissipation9.0Cooling8.4See all our test resultsResponsiveness8.7If you're a combination sleeper and want more support for occasional back and stomach sleeping without springing for a high-end mattress, consider the Tuft and Needle Mint. Overall, it's suitable for side and combination sleepers in a range of weight categories. This mattress has a Medium firmness level, but its upper layers are softer than the Helix Midnight Luxe 2025's. This helps it offer better body conformity for lighter individuals, making it a decent option for lighter side sleepers, despite its less contouring feel. It also offers great pressure relief for average-weight and heavier side sleepers and better support for most people, which helps keep your hips aligned with the rest of your body for side as well as back/stomach sleep.
Despite the more affordable price, it's also quite a durable mattress, since most of the foam layers are made of good- or high-quality foam, which will help it resist sagging for longer. It's cooling enough for hot sleepers and also offers fantastic motion dissipation, so you won't feel every move your partner makes. While you'll sink into it more overall than the Helix, its sleeping surface is responsive and has a less hugging feel.

Best Budget Mattress For Side Sleepers
Side Sleeping8.1Light Weight7.2Average Weight8.4Heavy Weight8.7Firmness LevelMedium-Plush (39 Pa/mm)Longevity6.7Motion Dissipation9.4Cooling8.1See all our test resultsResponsiveness7.7The Silk & Snow Mattress is a great budget-friendly option for side sleep, especially for lighter individuals looking for an affordable option. Its superb motion isolation also makes it particularly worth considering for couples, especially if you sleep lightly. This all-foam bed-in-a-box has a softer feel and better overall body conformity than the Tuft and Needle Mint, which helps it offer better pressure relief, particularly for people in the lighter and average-weight categories. Its memory foam upper comfort layer allows you to sink in significantly, but it isn't very contouring, so while you won't benefit from the extra pressure relief of a highly contouring mattress, you won't feel stuck in place. That said, it's a noticeably unbouncy mattress, which makes it feel more difficult to move around on.
Despite its all-foam design, it offers impressive cooling. Its superb motion isolation performance makes it well-suited for sleeping with a partner, since you won't feel most movements. It's also reasonably durable, since each layer is made of dense, good-quality foam. However, its edge support is just okay, so it's not ideal if you want a solid surface for getting in and out of bed. While it offers strong pressure relief for heavier individuals, it's not as supportive as the Tuft and Needle for people in that weight category, and you may prefer a more supportive mattress for side sleep.

Best Cheap Mattress For Side Sleepers
Side Sleeping6.7Light Weight4.9Average Weight7.1Heavy Weight8.1Firmness LevelMedium-Firm (54 Pa/mm)Longevity6.0Motion Dissipation8.8Cooling8.3See all our test resultsResponsiveness8.1The Allswell Hybrid is worth considering if you want to spend as little as possible on a mattress that performs well overall, especially if you're in the heavier weight category and want something more supportive than the Silk & Snow Mattress. With a Medium-Firm feel, it's the firmest mattress on the list so far, but it offers excellent body conformity for heavier side sleepers, relieving pressure on the arm and shoulder. It's also more supportive for people in that weight category than the previous pick, which helps ensure you sink in evenly. While its somewhat firm comfort layers aren't very enveloping, memory foam adds contouring and helps with pressure relief. It's bouncy and responsive, so you don't feel stuck in place.
It has good all-around performance as well, with impressive cooling and excellent motion dissipation. Firmer coils along the sides help give it very sturdy edges, so you can comfortably sleep near the side of the bed. However, it contains only one layer of good-quality foam, which is more prone to forming permanent impressions than more durable materials. It's also not as versatile as some of the previous picks: it doesn't offer enough pressure relief for lighter side sleepers, and while it's not a bad choice for average-weight side sleepers, you might prefer a more conforming mattress if you mostly sleep on your side.
Notable Mentions
-
Casper Snow (Canadian Version):
The Casper Snow (Canadian Version) offers even better pressure relief for lighter side sleepers than the Casper Snow (U.S.). Its cooling and motion dissipation are similar, but its edge support is worse, and people in other weight categories can get better support and similar pressure relief from the U.S. version.

DreamCloud Premier Hybrid:
The DreamCloud Premier Hybrid is a budget-friendly Medium-Plush mattress well-suited for average-weight and heavier side sleepers. It's a good alternative to the Silk & Snow Mattress if you want something bouncier, but its motion isolation isn't quite as good, and it's not as durable. It's also not as well-suited for lighter side sleepers.
See our review -
Saatva Classic (Plush Soft):
The Saatva Classic (Plush Soft) is a high-end Medium-Plush mattress that offers better pressure relief for lighter side sleepers than the Casper Snow. Like that mattress, it's cooling enough for hot sleepers, but its fairly weak motion dissipation makes the Casper a much better option if you sleep with a partner.
See our review -
Nolah Evolution:
The Nolah Evolution is a mid-range hybrid mattress with excellent pressure relief for average-weight and heavier side sleepers. Its highly contouring sleeping surface gives it a more enveloping feel than the Tuft and Needle Mint, but it's not as suitable for lighter side sleepers and offers worse support for almost everyone.
