Firmness Level
When buying a mattress for stomach sleeping, the first thing to think about is the firmness level and support. Prone sleepers want a significantly firm mattress to keep their neck and spine naturally aligned to prevent back issues. Such a mattress also needs to have a sturdy support system to ensure a flat profile.
Mattress Thickness
This aspect is easy to overlook when choosing the best mattress for a stomach sleeper. A rule of thumb when determining the ideal thickness is that taller beds feel softer. For stomach sleeping, you want a mattress that’s 10 inches in height. Anything above this increases the risk of spinal misalignment. Additionally, you want a mattress with a thinner comfort section to ensure a firmer sleeping surface that won’t compress under you.
Which Mattress Type?
Generally, hybrid (pocketed coils and foam) and innerspring mattresses are the best for stomach sleepers as they are relatively firmer than other mattress types. If you prefer foam beds, avoid overly soft mattresses that allow the lumbar region of your spine (lower back) to sink too far into the mattress.
As a stomach sleeper, your ideal firmness level when purchasing a foam mattress is dependent mainly on your weight. For lightweight to average weight people (9-16 stone), we recommend a memory foam or latex mattress that ranges 6.5-7 on the firmness level. Heavier individuals would prefer a firmer mattress to get the necessary support.
Temperature Regulation
Lying prone on a mattress means that almost the entire front of your body is in contact with the mattress. This can lead to heat build-up, making the issue worse for people who get hot at night. If you’re eyeing a foam mattress, consider a brand that employs proven mattress cooling technologies, such as gel infusions and cool layers.
Sleep Trial, Warranty, and Return Policies
While buying a mattress online has its perks, you’re not exactly sure how it will feel until it arrives. That being said, these three aspects - sleep trial, return policy, and warranty - should be among your primary considerations.
