Buying Guide: best mattress for belly and side sleepers

Firmness Level

Choosing the right firmness is essential for belly and side sleepers. A mattress that is too soft may cause misalignment, while one that is too firm can create pressure points.

Look for medium-firm to firm options that provide support without sacrificing comfort.

Pressure Relief and Support

Pressure relief is critical to avoid pain in hips, shoulders, and lower back. Zoned support systems and memory foam layers help distribute weight evenly.
