What is the best mattress for my specific sleep situation?

Your sleep position is the single most important factor: side sleepers need a softer mattress (medium or medium-soft) to relieve shoulder and hip pressure, while back and stomach sleepers need firmer support to keep the spine neutral.

Beyond position, body weight changes the equation. A 130-pound side sleeper who feels cradled on a medium-soft mattress may find the same mattress too soft and unsupportive at 230 pounds, needing a medium-firm instead. Hot sleepers should prioritize innerspring or hybrid mattresses over all-foam options, since coil layers move air and reduce heat buildup significantly more than dense foam layers do.

Side sleepers: medium to medium-soft mattresses (3–5 on a 10-point firmness scale) reduce pressure-point pain.
Back and stomach sleepers: medium-firm to firm mattresses (5–7) prevent lumbar sag and spinal misalignment.
Sleepers over 230 lbs typically need one firmness level higher than the standard recommendation for their position.
Hybrid mattresses combine pocketed coils with foam comfort layers, offering both bounce and pressure relief in one construction.
All-foam mattresses retain more body heat than innerspring or hybrid models, a documented trade-off for hot sleepers.

01How to Choose Your Mattress Type

Pick medium-soft all-foam if: you sleep on your side, weigh under 180 lbs, and rarely wake up hot during the night.
Pick medium-firm hybrid if: you sleep on your back or stomach, share the bed with a partner, or tend to overheat on dense foam surfaces.
Pick firm innerspring if: you're a stomach sleeper over 200 lbs who needs maximum lumbar support and the most airflow available.
Pick a zoned-support hybrid if: you switch positions throughout the night and need softer pressure relief at the shoulders with firmer support under the hips and lower back.
Pick a soft latex or soft hybrid if: you're a lightweight side sleeper under 130 lbs who finds standard medium mattresses too firm to relieve shoulder and hip pressure.
