Side sleeping is the most common of all the sleeping positions, and there’s a lot of information available on the best mattress for side sleepers. We’ve ranked the best mattresses for side sleepers – view the list below!

  1. Firm and ample support: ability to keep spine aligned and elongated

A mattress with good support and some give can help align and lengthen the spine and body in a neutral position, which helps prevent back and neck pain for side sleepers. When a mattress is too soft, it can cause the body to sink into the mattress too much, causing the spine to curve.

  1. Soft enough: relief on pressure points

Mattresses for side sleepers need to be soft enough to allow for good circulation and to relieve pressure points in the hips, shoulders, and neck. For example, foam mattresses perform well by taking tension away from pressure points. Also, mattresses with a soft outside layer, like a top or cover, are great for relieving pressure.

  1. Contours: conformity to the body for muscle relaxation

Side sleepers also prefer a mattress that will conform to and cradle the body. The mattress takes away pressure and allows the muscles to relax, which is ideal for getting a good night’s sleep.

  1. Correct thickness and firmness: based on body weight

A mattress with the correct thickness is important for side sleepers, too. Mattress thickness and firmness needs vary for people with different weights. For example, heavier people may have different needs for comfort. If the firmness level is too high for a more petite person, it can cause aches and pains because the mattress doesn’t conform well to the body.

  1. Stays cool and breathes well

Side sleepers may also prefer to have a mattress that has technology built in to cool and breathe well. Many hybrid, foam, and spring mattresses have built-in layers for cooling and breathing.

Firmness and support for side sleepers

It is key for side sleepers to pick a mattress that both:

  • Supports the body enough to keep it in a comfortable position
  • Is soft enough to provide pressure relief

The goal is to find a mattress with support that is rooted in the center of the mattress with soft and firm areas built in for conforming and giving in to the weight and pressure of the body. It is recommended that the comfort level is 5 to 10 (or a soft to medium firm mattress).

Side sleepers can face several challenges because of the sleep position:

Body misalignment

When a side sleeper moves by twisting or curling legs in the opposite position of the upper body, it causes muscles in the back and the lumbar spine to go out of alignment. This movement can cause and worsen lower back and neck pain. Side sleepers can try to prevent this by sleeping in positions that ensure alignment of the spine and using a mattress that has enough support and softness.

Skin aging and wrinkles

Side sleeping can also cause the aging of skin and wrinkles while one side of the face is on the pillow.

Sagging breasts

Although sleeping on the side is beneficial because it elongates the spine, this position can also cause breasts to sag.

What is the best type of mattress for side sleepers?

There are many mattress types and several kinds of mattresses that will achieve both the great support and correct firmness range for side sleepers. Consider these suggested side sleeper mattress varieties below.

The best kinds of mattresses for side sleepers are:

  • Foam mattress (poly and memory foam)
  • Hybrid mattress
  • Innerspring

Learn more about the different kinds of Mattress Support Cores.

Note: Side sleepers should consider all types of mattresses with a soft to medium firmness somewhere between 3 to 6 on a scale of 1 to 10 (10 is the firmest). And, consider starting with a 2 to 4 inch soft top comfort layer.

Foam mattress (poly and memory foam)

  • High-density foam layers (several grades of poly foam) for support
  • Combination of foam layers used for both support and comfort
  • High-density foam layers (several grades of memory foam) for comfort for cradling body of side sleeper for body alignment
  • Cooling technology to avoid heat trapping
  • Consistent support
  • Elasticity of memory foam allows mattress to bounce back to original position (slower response time, however, compared to latex)
  • Excellent conformity and relief for pressure points for side sleepers (allows for horizontal alignment of shoulders, hips, and spine)
  • Consider medium thickness of memory foam (comfort layer) combined with other materials

Hybrid mattress (foam and coil)

  • Combination of both coils and foam(s)
  • Coil support system gives great core support (coil types include: bonnell, offset, continuous, and pocket coil) layered with foam or quilting
  • Support helps keep spine alignment and body in position
  • Foam layers are used for comfort and added support (memory foam, latex, polyfoam, natural fibers)
  • Consider medium thickness of comfort layers to help conform to body to help with spine alignment and pressure relief
  • Good conformity with thick memory foam layer(s)
  • Great support, but may break down over time

Innerspring mattress

  • Steel coil support system (coil types include: bonnell, offset, continuous, and pocket coil) layered with foam or quilting
  • Coils range in thickness from 12.5 to 16 gauges and thinner coils can more easily shape themselves to contour to the body, while thicker layers provide support for holding up the weight of the body
  • Conformity depends on comfort layers (materials like memory foam, latex, polyurethane foam, and natural fibers)
  • Support may breakdown over time
  • Consider medium thickness of comfort layers to help conform to body to help with spine alignment and pressure relief
  • Resilient and durable

A few other kinds of mattresses side sleepers can consider are latex and adjustable air mattresses.

Latex mattress

  • Latex foam layers (mainly Dunlop and Talalay)
  • Latex layers are for both support and comfort
  • Great for core support layers and comfort layers
  • Conforms well to the body and relieves pressure points
  • Only a mattress with a latex core should be in this category
  • Good durability and long lasting
  • Elasticity is good, and latex mattress will bounce back into original position after being compressed

Adjustable air mattress

  • Adjustable chambers of air used
  • Foams and fiber layers, too
  • Provides a lot of support
  • Firmness can be adjusted for personal preference
  • Adjustments to mattress can allow for higher or lower position on certain part of the body that are heavier
  • Don’t have issues with mattress sagging
  • May be too firm for some sleepers (basic or no comfort layer)
  • Definitely needs an effective comfort layer to provide enough softness for comfortable sleeping

What else should a side sleeper consider?

After selecting the proper mattress, the next step is finding the right pillow — it’s just as important! Side sleepers should look for the following qualities in a proper pillow (for supporting the head and neck, and possibly for a pillow that goes in between the legs or knees) for the side sleeping position.

Changing sleep positions or sides

Another thing side sleepers should consider is the way in which they change sides during the night. It is suggested that sleepers avoid turning or twisting at the waist, but that they instead move the whole body together by tightening the core and bending knees together toward the chest when rolling over.

Also, side sleepers should always keep alignment in the ears, shoulders, and hips when sleeping and when turning or changing positions or sides.

The best mattresses for side sleepers

No matter the sleeping position, the right mattress is important for getting healthy and consistent sleep. Luckily for side sleepers, there is a wide variety of mattresses available that are suitable for the most common sleeping position.

Side sleepers have specific needs that are based on the shape of the body in the side sleeping position.

Some key requirements to look for in The Best Mattresses for Side Sleepers are:

  • Firm and ample support to keep the body and spine aligned
  • Soft enough to offer pressure relief
  • Conforms to the body to allow muscles to relax
  • Thickness and firmness are appropriate for body weight
