Best Mattresses for Side Sleepers

A guide for side sleepers to find the best mattress for their sleep position and the benefits of sleeping on your side.

By Natalie Yerger

Expert-Reviewed by Dr. Navin Ramchandani, MD.

Did you know that almost 70 percent of adults sleep on their sides for at least a portion of the night? For many, myself included, there’s no cozier position than side sleeping. Whether you like to extend your legs fully, keep one straight, or revert to the fetal position, curling up on one side is certainly a comforting way to rest.

Much like back and stomach sleepers, side sleepers need a mattress that supports their unique needs. A mattress that allows the pelvis to sit too high or low can place undue pressure on the spine, which translates to pain in the hips and shoulders.

In this guide, we’re covering our top mattresses for side sleepers along with a detailed list of qualities to look for and the benefits of sleeping on your side.  Alternately, click here if you want to see our best mattresses overall or here to see our best mattresses for back sleepers.

Best Mattresses for Side Sleepers

Saatva Classic

Editor's Pick

Saatva is one of the first direct-to-consumer online mattress companies. The Saatva mattress is a little different from the other “bed-in-a-box” companies out there because this one doesn’t come in a box at all. It’s a regular innerspring mattress delivered to your door by delivery professionals.

High quality and custom firmness options

The Saatva is customizable (both firmness and height), meaning that it can work well for almost any sleeper, regardless of body weight or sleeping style. Firmness options include Plush Soft (4), Luxury Firm (6), and Firm (7.5), and you can choose from 11.5- and 14.5-inch profiles. Keep in mind that the Saatva’s responsiveness may make it unpleasant if you wake easily at the movements of a partner, as it doesn’t shine in the motion isolation department.

All Helix mattresses are hybrids, which means they’re a mix of foam and coils.

The Nectar is a memory foam mattress with a cover of cooling Tencel, one inch of gel memory foam for a plush feel on top, a transitional layer with quick response time, and a supportive, durable base layer at its foundation. While appropriate for any sleep position, this is an affordable option for side sleepers.

The Nectar comes in at a very friendly price point without sacrificing any of the features side sleepers need.

Puffy Lux

Absorbs your body heat to keep you cool all night

The Puffy Lux is an all-foam, four-layer, bed-in-a-box mattress with a soft feel. The company took its original mattress, the Puffy, and added a 2” gel-infused foam to create the Puffy Lux; the extra layer not only gives the bed a thicker profile but creates a more supportive surface while still being a luxurious mattress.

Think of the Puffy Lux as the step up from the original Puffy. It offers the same pressure relief, weight distribution, contour, and cooling benefits of the original with the addition of a layer for added spinal support and comfort. This added layer, made of Body Adapting Dual Cloud Foam, is supportive enough for side sleepers but appeals to those who enjoy an especially cushioned feel.

Dual-sided design.

The Layla is a copper-infused memory foam mattress that’s double-sided, allowing you to choose from two firmness levels in the same mattress. The medium-soft side is pressure-relieving, and the firm side provides more support. 

Regardless of which side you choose, the cover design on this bed will keep you cool and makes flipping the bed a cinch. We recommend the medium-soft side for most side sleepers, but heavier individuals may enjoy the firm side. As an added bonus, the foam in this mattress is copper-infused, which keeps you cool by drawing heat away from the body. The copper also kills bacteria naturally, helping extend Layla’s lifespan.

Casper Hybrid

Zoned comfort and the addition of a coil layer

This hybrid mattress takes features from the original Casper, an all-foam mattress, and marries them to other materials sleepers desire in a mattress. Pocketed coils steal the spotlight in its makeup and add extra bounce. Other materials include latex, memory foam, and poly foam, a winning combination for support and comfort.

Casper aims to provide a balance of comfort and support with this hybrid, and we think they nailed it. If you’re a side sleeper who occasionally sleeps on your back, we recommend this option because it’s supportive enough for both positions but feels softer when you’re on your side. While some sinking will occur in the top foam layers, it should be just enough to provide satisfying relief for side sleepers while distributing body weight evenly throughout the mattress.

The soft foam layers of the AS4 will help you feel cradled and comforted without allowing your hips and shoulders to sink too far into the bed.

Soft and plush bed that's perfect for side sleepers

The AS4 is a memory foam mattress with a medium-soft feel. We love this mattress for a lot of reasons; the eco-friendly Bio-Pur foam used in construction, how it keeps sleepers cool at night with a breathable design, and how generally comfortable it is. However, we love this mattress for side sleepers for even more reasons! This medium-firm feel is just soft enough to cradle the hips and shoulders in the mattress as you get comfortable.

There is a delicate balance between too firm and top soft when it comes to side sleepers and the AS4 does. great job for light to average weight sleepers. If you are heavier sleeper (over 230 lbs.) you may find you sink too much into this mattress and become uncomfortable. This mattress also does a good job with motion isolation, making it ideal for couples and combination sleepers who spend time on their back and side. Stomach sleepers will probably find their hips sink a bit too much to keep the spine aligned on this mattress.

Top of the line cooling technology

When shopping for a mattress there are only a few things as important as sleep position to consider, and one of those is how hot you tend to sleep. Not only is the Cocoon Chill engineered to allow the hips and shoulders of side sleepers to be cradled and supported without them feeling jammed, but it is also one of the coolest memory foam beds ever made.

Some side sleepers think they have to compromise when it comes to memory foam, seeing as it is usually one of the most popular options so they can receive the contouring and pressure relief they need on sensitive areas. However, when Sealy made the Cocoon they knew they wanted to create a mattress that didn’t compromise anywhere, and made it available at a budget-friendly price point.

Unique AirFoam that cradles the hips and shoulders

The Nolah Original mattress is a medium-soft, polyfoam mattress that features three layers of foam and an organic cover. The 2.5” top layer is made of Nolah’s cooling, extra-deep AirFoam, which creates motion isolation, especially on the soft side (related: best soft mattresses).

The fact that this mattress is not memory foam bears reiterating. In fact, Nolah claims that the AirFoam sleeps cooler, provides four times the pressure relief, and is 300% more durable than memory foam. It is a great mattress for side sleepers, hot sleepers, and couples, due to great motion transfer reduction, meaning you won’t be bothered by your partner’s movements throughout the night.

The Leesa Hybrid is an excellent option for many groups of sleepers. Obviously, one of our favorite matches for this mattress are people with shoulder pain, who still like to sleep on their side. This mattress has a great balance of give and support, so you will not feel like your shoulders are jamming against the mattress when you lie down, and you will also still feel like the rest of your body is aligned.

This is also a great option for couples, even couples who have different sleeping positions from one another. The Leesa Hybrid performs above average for all sleeping positions, so if you and your partner have differing concerns about a mattress you may find this one is a happy medium. Since it is a hybrid, you will get a nice amount of airflow to keep you cool throughout the night.

What Should Side Sleepers Look for in a Mattress?

Pressure Relief

According to Dr. Navin Ramchandani, “Every sleeping position creates zones of pressure along the body. For side sleepers, these occur at naturally contoured areas that press deeper into a surface when you’re lying laterally (on your side): the shoulders and hips.”

If you’re sleeping on your side and have the wrong mattress, one of the first red flags is pain or numbness in these areas upon waking. A mattress that’s healthy for side sleeping will contour to the body and provide just enough give to allow these areas to relax throughout the night. 

Firmness

Most shoppers think of firmness only in terms of preference, but the firmness of a mattress will impact how it sleeps. Side sleepers need a mattress that’s soft enough to contour to their body’s curves. A lack of contour means a lack of support, creating pressure points that lead to back, neck, and shoulder aches and pains. 

For the majority of side sleepers, soft to medium-firm mattress strikes a balance, but keep in mind that this will vary by size. If you’re on the heavier side or have a large build, you’ll sink further into the mattress and may find better support in a firmer setting. If you’re petite, a softer mattress may feel supportive enough for you.

Contour

“For side sleepers, its important to find a mattress that is soft enough to contour to your body’s curves. A lack of contouring means a lack of support, which can lead to other issues like creating pressure points that lead to the back and neck. This can lead to shoulder pains and aches,” according to Dr. Navin Ramchandani. 

Memory foam products are known for their ease in contouring to the body and the slow return back to the original form once the pressure is released. Hybrid versions of innerspring mattresses will offer a greater degree of contouring than traditional innerspring styles. To some, latex mattresses surpass even memory foam in their ability to contour. Natural latex has a less pronounced contour than memory foam, meaning that sleepers will feel supported even if they move throughout the night. 

Spine Alignment

When you’re lying on your side, the ideal alignment for the spine is straight. This often surprises people who imagine sinking deeply into a mattress to sleep. “While the spine has a natural ‘S’ curve when viewed from the side, it should be completely straight from an anterior (front) or posterior (back) view. Bending to the side occasionally is completely normal, but remaining in that position for more than a few seconds, much less throughout the night, isn’t healthy,” says Dr. Navin Ramchandani, MD. 

It’s crucial to side sleepers’ long-term health to find a mattress that encourages proper spinal alignment. It needn’t be excessively firm but should prevent exaggerated bending of the spine.

What Type of Mattress is Best For Side Sleepers?

There’s no single mattress type that will suit side sleepers across the board. From innerspring to hybrid, memory foam, and latex, each type has benefits. Whether or not a mattress is ideal for an individual is dependent upon the mattress’s construction and the sleeper’s preferences, size, and build.

We can, however, find commonalities in materials used in the top-ranked beds for this sleeping type. For example, memory foam is often used for pressure relief in the top layers of these mattresses. Additionally, we noticed that mattresses with inner springs that support body weight yet allow for body contouring were common.

There’s no single “right” material, but be on the lookout for these two. Beyond them, it’s up to preference: pocketed coils reduce motion from a partner, memory foam can have a firmer base, latex is eco-friendly, and so on. 

Benefits of Sleeping on Your Side

Side sleeping is the second most recommended sleeping position by doctors, and it offers many health benefits when done properly. It’s gentler on the neck than stomach sleeping, which is known to cause snoring, sleep apnea, and back problems and, for many, more comfortable than back sleeping.

If you think sleeping on the left or right side is little more than the flip of a coin, think again. It’s been proven that sleeping on the left is more beneficial. Sleeping on the right side can aggravate acid reflux and heartburn, both of which left-side sleeping alleviate. Due to the location of the body’s organs, sleeping on the left also boosts digestion, improves circulation, assists brain waste filtering, and stimulates lymphatic drainage.
