What to know before buying

The title and size details give a 27 cm or 10.6-inch depth, but the listing also describes an upgraded seven-zone independent spring design without clearly establishing whether the seven zones refer to the spring system or the seven listed layers. Customer feedback is mixed on firmness, with some saying it does not feel medium firm. Confirm the selected listing's dimensions, trial terms and spring-zone details before buying.
