Stomach sleeping fails on hip sink
The best mattress for a stomach sleeper is a firm one with a shallow comfort layer, because the hips and belly carry most of the load in this position.
Lying face down, the heaviest part of the body sits in the middle of the mattress. If the comfort foam lets the hips drop even an inch below the shoulders, the lower back arches. A soft, deep-hugging bed that suits a side sleeper is the wrong tool here. The Beautyrest Black Series One extra-firm review shows the pattern clearly: it measured 8/10 firm, and its stomach results get better as body weight rises.
Body weight changes the answer a lot in this position. A sleeper under 130 lb compresses the comfort layer less, so a 6 or 7 out of 10 bed can work: the Leesa Legend and Helix Plus are both recommended there. Above 230 lb those same beds drop to “possible”, and the firmest builds do best.
Wear matters here too. Comfort foam over the hips is usually the first part of a mattress to soften, and in this position that shows up as lower-back stiffness. Use the trial period to check posture, and see the mattress lifespan check when the bed starts to feel deeper.
