Abstract

The invention relates generally to a seating system and more particularly to seat cushion assemblies having a rearward depression and cushioning insert tailored to fit under the skeletal structure of the user. In particular, the assembly preferably includes an intermediate insert which fits within a base depression and a cushioning insert which can be a fluid bag, air bag, foam or gel. The insert is generally oval shaped and has a rounded bottom.
This enables the cushion to be used to fit under the seating bones so as to provide a proper pelvic tilt.
Further, the insert can be moved in order to provide controlled movement of the pelvis over time.
A first cushioning insert is generally constructed of a material forming baffles so as to define air chambers and having a right and left seat bone area. A
second design has a top and bottom so as to define the fluid envelope separated by central baffle having apertures to allow fluid communication between the right and left portions. In a further aspect, the invention includes tapered wedges which can be removed to lower one side of the leg well and the base cushion to allow for self-proportion on the part of the user. Rigid stabilizers support the edges of the base cushion.
