Abstract
An adaptive seat and backrest cushion, divided into a seat cushion and a backrest cushion of essentially the same construction. A number of webs are introduced between an upper skin and a lower skin of an airtight shell by welding or gluing. The first webs are of simple construction, the second webs are of double construction each with a cavity between the webs. The space within the shell is filled with compressed air at a pressure p.sub.1, the cavities can be pressurised as required with compressed air at a pressure of p.sub.2, where p.sub.2>p.sub.1. The thickness as well as the softness of the seat or backrest cushion can thus be altered.
