Best mattresses for side sleepers

Take your sleeping to a whole new, comfier level.

Are you a serial side sleeper? If so, you might need a different type of mattress than the average back or stomach sleeper.

Why? When you sleep on your side, you have more potential pressure points than when you lie on your back or stomach. You need a mattress that not only alleviates these pressure points, but also helps keep your spine in proper alignment while still providing a comfy night’s sleep.

We took into consideration firmness, support, pressure-point relief and spinal alignment when compiling this list of the best mattresses for side sleepers.

Editor's Pick

A medium-firm mattress with plant-based memory foam to keep you cool.

Amerisleep's memory foam alleviates pressure points for side sleepers by molding to the body. The A3 is medium-firm, which means there should be enough oomph to support a straight line from your head to your hips.

Folks on the larger side might opt for the firmer A2, while smaller people may prefer the softer A5.

We also like that the memory foam is made of plant-based Bio-Pur, which helps prevent heat build-up while you're catching Zzzs.

How will my sleep quality improve with a new mattress?

A whopping 47% of Americans sleep on their sides in some variation of the fetal position. But most people report getting below-average sleep quality regularly. If your mattress isn’t the optimal type and firmness level for the position you usually sleep in, you can’t expect to get a great night’s rest.

When searching for a new bed for side sleepers, look for these qualities:

  • Firmness and support. Most sleep experts say to look for a medium-firm mattress if you’re a side sleeper, since you don’t want your hips to sink down to the ground and throw your spine out of whack. But if you like a softer feel, go for a mattress that still offers plenty of support, such as a hybrid spring-coil and foam construction.
  • Spinal alignment. If you sleep on your side, it’s important that your spine is properly aligned and stays that way throughout the night. Lots of online mattress brands boast “added lumbar support” or “spinal alignment support” features that help the mattress cradle and support your natural curves.
  • Pressure-point relief. Side sleepers have more pressure points than back or stomach sleepers. Look for a mattress that’s designed to help relieve pressure points while still offering support.
  • Pillows. If you’re thinking of upgrading your mattress, you might want to throw in a new pillow, too. Side sleepers usually need a thicker, firmer pillow to support their neck.
