Look for resistance to deep sink
A firmer or more supportive configuration is commonly considered because it can reduce excessive compression under the torso.
Body weight changes the equation
Heavier sleepers compress comfort layers more deeply, so a firmness that works for one person may feel different to another.
Aviya context
Aviya positions its Firm model toward back sleepers and heavier sleepers. Stomach sleepers considering Aviya should compare all three published comfort levels and use the trial responsibly.
