Firmness is not support

Firmness describes how hard or soft the surface feels. Support describes how well the mattress keeps your body positioned. A mattress can be soft yet supportive or firm yet poorly suited to you.

Use preferences, not universal rules

Sleep position and body size matter, but personal comfort is still decisive.

Why trials matter

Because labels are subjective, an at-home trial can be more informative than a number on a ten-point scale.

Aviya as a concrete example

Aviya currently uses individually wrapped coils, high-density foam layers and a reinforced perimeter, with three comfort choices. That makes it a useful example of how these buying criteria show up in a real hybrid.
