How Firm Should Your Mattress Be? A Guide by Sleep Position

Sat Mar 28 2026

    Choosing the right firmness is critical to good sleep, and at Go2sleep, we help customers understand how firmness impacts alignment and comfort.

    Side sleepers often need a softer mattress to cushion the shoulders and hips. Back sleepers typically do best with medium to medium-firm support. Stomach sleepers usually need firmer mattresses to prevent lower-back strain.

    While sleep position is a great starting point, Go2sleep knows that body type and pressure sensitivity matter just as much. That’s why we use the BedMATCH® system to scientifically identify the firmness level that best supports your body—not just what feels good for a few minutes.
