Our Sleeping Ninjas have compiled a simple guide to help you understand your needs as a side sleeper. Here you’ll find what we deem to be the best mattresses for side sleepers—mattresses that will help you to sleep soundly and wake up feeling refreshed.

Factors for the Best Mattress for Side Sleepers

  1. Pressure relief: Side sleepers tend to create too much pressure on their hips and shoulders. Take a look at the image above, courtesy of Morphiis. This image shows us the most common pressure points that will be afflicted by the wrong choice of mattress. The best mattress for side sleepers will adapt to your body’s shape, relieving these pressure points.
  2. Spinal Alignment: The best mattress for side sleepers will also provide support for the spine, creating a proper alignment while ensuring stability as you sleep. The right firmness and mattress quality will help you maintain an ideal posture throughout the night.
  3. Firmness: Side sleepers should look for a mattress that is medium-soft. A firm mattress will provide too much resistance to the pressure points, creating what can be seen in the image above. The right firmness will also help keep your spine aligned, creating a comfortable sleeping position which prevents tossing and turning.
  4. Choose the right pillow: oftentimes overlooked, side sleepers should invest in the proper pillow that matches the natural shape of your neck, reducing the pressure caused by sleeping on your side. You can also place a small pillow between your knees to help prevent hip rotations during the night.
  5. Keep your spine properly adjusted: it is best to get in the habit of adjusting your spine when you are about to go to sleep, as well as when you wake up in the middle of the night. Do this by creating a straight line between your neck and your pelvis. Your hips and pelvis should remain straight throughout the night. A mattress that’s properly adjusted for side sleepers will help you get into that position naturally.
  6. Think about your partner: while you may be a side sleeper, there’s no telling what your partner likes and how they prefer to sleep. Therefore, try to find an option that fits both. The best possibility is finding a mattress that allows for modifications, but a medium-firmness mattress with memory foam would usually do the trick.

“This was the best purchase I have made all year! The mattress came compact enough that we didn’t have to have help to carry it. The hardest thing was waiting 3 days to let it fully fluff up. My husband and I have been sleeping on this mattress for 9 days. We both suffer from arthritis and our traditional mattress was not cutting it anymore. Each morning we have woke up without those ache and pains we have been dealing with for so long. This mattress gives us that firm support we need, but we still get soft cradling our bodies crave. This is first mattress that we both are happy with!”

best mattress for side sleepers eco terra

The Eco Terra Latex Mattress

Absolutely one of the most comfortable mattresses for side sleepers, the Eco Terra Latex Mattress comes with three unique features that make it a great, affordable purchase.

First, the organic cotton is super soft and creates a very welcoming feel to the bed—great for those who find it hard to fall asleep. Underneath is the full natural latex layer that contours perfectly around your body, helping to relieve the pressure pains and creates a stable support for your back.

The fabric-encased coils eliminate motion disturbance, helping you sleep regardless of your partner’s habits. Quantum coils additionally reinforce the mattress all around, providing a relaxing sleeping space all the way to the edge.

Another significant factor is that the coils are a great substitute for memory foam. Memory foam tends to retain heat and is not suitable for very hot sleepers. With the coils, there is a 28% reduction in heat, creating a super cool, breathable atmosphere around your body.

PROS:

  • Significantly cooler than memory foam mattress, due to increased air-flow between the coils
  • Perfect medium firmness makes this a great mattress for side sleepers
  • Fully organic mattress cover provides a relaxing feel as soon as you hit the bed
  • All-natural latex layer provides the much needed body contouring for side sleepers, helping to reduce pain and align the spine
  • Fabric-encased coils minimize motion transference and help create a buoyant feeling
  • Quite affordable for the quality of the mattress
  • Built to maximize REM sleep, which is necessary to feel refreshed when you wake up

CONS:

  • The bed is quite bouncy and may take you some time to get adjusted
  • The mattress is heavy and may be hard for you to lift once you get it
