While sleeping on your back is often recommended as the optimal sleep position, research suggests that side sleepers enjoy plenty of benefits, too. Sleeping on your side can help keep your breathing airways open throughout the night, reducing snoring and symptoms of sleep apnea. Plus, a 2015 study from the Journal of Neuroscience indicates that the position can more effectively remove brain waste than other positions, potentially helping to reduce your chances of developing Alzheimer's and other neurological diseases.

However, if you sleep on your side with the wrong type of mattress, then you can potentially cause more harm than good. If the mattress is too firm or soft, it may create pressure on your spine, resulting in hip, shoulder, and back pain. What you essentially need is the Goldilocks of mattresses — one that falls right in the middle of the soft-firm spectrum.
Below, we cover the 10 best mattresses for side sleepers so you can purchase the right one for your body and budget. (All prices shown are for the Queen size.)
Best Overall: The Casper Hybrid Mattress, $1,395
With its mix of soft, pocketed springs and layered memory foam, the Casper Hybrid strikes the perfect balance between soft and firm, making it a great overall option for side sleepers. And because some people find that memory foam mattresses feel too warm, the mattress is designed with open-cell foam that promotes airflow and nightly comfort. It also comes with enhanced edge support compared to other Casper mattresses, making it easier on your body to get in and out of bed. And to make sure you're completely happy with your purchase, the brand offers a 100-night free trial, free shipping and returns, and a 10-year warranty, so you can be totally confident in your purchase and its longevity.
Best High-End Option: TEMPUR-Adapt Mattress, $2,299
TEMPUR-Pedic mattresses have long been a favorite among mattress enthusiasts, but they're definitely at the high-end in terms of price points. However, you also get plenty of quality assurance with that price, including a 10-year warranty, white glove delivery, and a 90-day risk-free trial. The brand's TEMPUR-Adapt Series, specifically the Medium Hybrid option, is ideal for side sleepers. The mattress pairs 1,000 premium spring coils with memory foam comprised of the same material developed by NASA to absorb the g-force of astronauts during shuttle launches. It also features premium-knit technology that stays cool to the touch, keeping you comfortable all night long.
Best for Pressure Relief: The Puffy Lux Mattress, $1,799
If you find that mattresses typically put too much pressure on certain points on your body, then you'll love the Puffy Lux mattress. The pressure-relieving design features two layers of foam that work together to eliminate pressure points while providing optimal spinal alignment for side sleepers. Additionally, it comes with a Climate Comfort layer that creates a subtle warming effect during cooler nights and a cooling effect during warmer nights to maximize comfort. The mattress also comes with a free 101-night sleep trial and lifetime warranty, ensuring that it will keep you comfy and cozy for as long as you need it to.
Best Budget-Friendly Pick: Nectar Memory Foam Mattress, $1,298
The Nectar Memory Foam Mattress offers side-sleeping benefits at a budget-friendly price. The mattress features several different layers of memory foam, including a supportive base layer, a transitional middle layer that responds to your body weight, and a top layer of gel memory foam that gives the mattress a soft and cushy feel. It's also topped with a thin, cooling material that will keep you from getting too hot during the night. But one of the main aspects that sets this mattress apart from many others is its 365-day home trial that allows you to try the mattress for a full year without committing to buying it. Once you do commit, and we bet you will, you'll receive a forever warranty, so you know you're getting a mattress that can truly withstand the test of time.
Best for Couples: Helix Midnight Luxe Mattress, $1,949
If you and your partner don't share the same sleeping preference, but one of you is a side sleeper, this mattress is your answer. Not only is it the brand's bestselling product, but it is also the winner of a multitude of awards and accolades — both GQ and Wired named it as their best mattress for 2019 and 2020. The 14-inch-thick mattress is a medium firmness mattress specifically designed for side-sleepers with a layer of memory foam in this mattress for pressure relief around the hips and shoulders.
Best Innerspring Option: Saatva Classic Mattress, $1,695
For those partial to innerspring mattresses, the Saatva Classic Mattress is truly one-of-a-kind. Combining the wonders of a plush Euro pillow top and patented spinal zone technology, this option provides contoured support, extra cushioning, and healthy back support for a perfect night's sleep. Its durable edge support features a high-density foam rail construction that encases the perimeter of the mattress to prevent sagging, which makes getting in and out of bed easier. Not to mention, it comes in three firmness options — plush soft, luxury firm, and firm — to suit your needs. And with a 180-night trial, you'll have enough time to decide if it's right for you.
Most Versatile: TEMPUR-CLOUD Mattress, $1,999
This model comes equipped with four layers: a 360-degree moisture-wicking stretch cover, the brand's notable TEMPUR comfort layer for all-over cushion, the TEMPUR firmer support layer that adapts and conforms to your body, and a durable base layer that provides all-night support. One of the best features of this mattress is its ability to reduce motion transfer. So, if your partner tends to twist and turn at night, you won't be disturbed.
Best Cooling Mattress: Cocoon Chill Hybrid Mattress, $1,699
The Cocoon Chill Hybrid Mattress may be a bit pricey, but its cooling benefits make it worth the splurge. With a cooling cover that's designed with a proprietary "phase change material," it works to absorb and dissipate heat which helps you feel cooler as you sleep. It's also made with Bolsa technology coils that channel excess heat through breathable springs to keep you cool around the clock. The mattress also features perfect fit memory foam that contours to your body and Active Support Technology that offers more targeted support for your body size, shape, and sleep position. Plus, for $200 more, the brand just released an Extra-Chill Hybrid upgrade that adds cooling memory foam and is woven with advanced cooling yarn.
Best Reversible Mattress: Layla Memory Foam Mattress, $1,099
If you struggle to find the right firmness in a mattress, the Layla Memory Foam Mattress is a dual-sided offering that won't steer you wrong. It features both a soft and firm side that allows you to change the support level to suit your needs. (In other words, it feels like having two beds in one.) The foam mattress is infused with conductive copper gel which prevents the foam from overheating and keeps you cool at night. Plus, the copper is antimicrobial, so every time you lay on the mattress it compresses to create a barrier that blocks out odor-causing bacteria. Additionally, you'll be able to enjoy a lifetime warranty should your mattress sag, lose shape, or height, or if the foam splits or cracks.
Best Adjustable Mattress: Sleep Number 360 p6 Smart Bed, $3,099
The Sleep Number 360 p6 Smart Bed offers plush, pressure-relieving comfort with cooling technology that doesn't wane when your partner's sleeping next to you. There are adjustable chambers for each side of the bed that can be moved as needed. It's also designed with biometric sensors that can tell if you switch positions while you sleep and will automatically adjust to keep your preferred firmness in place. With a 15-year warranty, you can rest assured that you'll get a good night's sleep for years on end.
