Stomach sleepers need a firm or medium-firm mattress that keeps the hips level with the shoulders and prevents the pelvis from sinking into the surface. When hips drop below shoulder level, the lower spine hyperextends, which can lead to morning back pain and discomfort. A supportive mattress helps maintain a neutral spinal alignment throughout the night. Rooms To Go carries mattresses from trusted brands like Sealy, Beautyrest, Tempur-Pedic, and Serta that are well-suited for stomach sleepers.
