Start with sleeping position
Side sleepers often value more cushioning at shoulders and hips, while back and stomach sleepers commonly seek more resistance against excessive midsection sink. Individual needs vary.
Account for body weight
The same mattress can feel firmer to a lighter person and softer to a heavier person because each compresses the comfort layers differently.
Use your own history
Your experience on previous mattresses is valuable. Note whether you disliked excessive sink, pressure at shoulders/hips, or a surface that felt too hard.
Treat scales as approximate
Firmness scales are not standardized across brands. Aviya publishes three levels; compare them in our Aviya firmness guide.
