Starting range

Stomach sleepers often need enough firmness to prevent the midsection from sinking excessively. Sleep Foundation's published firmness guidance generally moves firmer as body weight increases. No single firmness number is guaranteed to work for every stomach sleeper.

Body weight matters

Lighter bodies compress a mattress less and can experience the same model as firmer. Heavier bodies sink farther into comfort layers and often benefit from more support or firmer materials.

Pressure relief vs support

Softness and support are not opposites. A mattress can have a cushioned surface over a strong support core. The right balance is enough contouring to reduce concentrated pressure without losing stable support.

Hybrid considerations

Hybrids add responsiveness and airflow through the coil core. Pocketed coils can also adapt independently under load. The comfort-layer thickness and firmness still determine much of the surface feel.

Where Aviya fits

Aviya's three choices span Plush 3.5/10, Luxury Firm 5.5/10 and Firm 8.5/10 on its own scale. Aviya's own guidance positions those choices differently by sleep position; use that as manufacturer guidance, then compare it with your body weight and preferences.
