Abstract
Abstract This invention is directed to a novel adjustable multi-compartment inflatable form support. More particularly, this invention pertains to a novel multi-compartment pneumatic or hydraulic support form which has multiple chambers, each of which can be inflated or hydraulically filled to different pressures to provide different shapes and degrees of support. An adjustable multi-compartment inflatable or hydraulically filled support form comprising: (a) at least one first hollow chamber which can be individually inflated or hydraulically filled through a specific resealable valve; (b) at least one second hollow chamber which can be individually inflated or filled through a specific resealable valve; and (c) at least one third hollow chamber which can be individually inflated or filled through a specific resealable valve.
