ABSTRACT:
A seat housing a multiplicity of adjustable horizontal planes connected to a processor in turn connected to an input device responding to a prerecorded spinal profile information of an individual's spinal configuration submitted to the input device. A seat pan, inclinable and pivotally mounted, on rails that permit horizontal movement relative to the back rest is also supported by a viscoelastic layer. Horizontally adjustable headrest is mechanically linked to vertically adjustable arm supports to allow vertical movement of the assembly, matching that of the vertical displacement of the seat pan when the seat is in use.
