How Do Adjustable Firmness Mattresses Work?
Adjustable-firmness mattresses commonly use internal air chambers. A pump adds or removes air, changing chamber pressure and the way the support core responds under the sleeper.
The important distinction
Pressure adjustment changes the support system, but it does not make every part of the mattress disappear. Foam, latex, quilting and pillow-top materials above the chamber still influence cushioning and surface feel.
What to check when shopping
A dual-side design lets two sleepers use different settings. A zoned design can subdivide support further. Smart systems may also store settings or automatically respond to movement.
