DEFINITION

Classification: 5/653

Removable support specially adapted for seating:

(under subclass 652) Subject matter comprising a portable pad or cushion with a supporting surface, which due to its

support characteristics, construction, shape or size is specially adapted to support a user's buttocks in a seated position, with the pad or cushion being removably positionable on a chair, wheelchair or similar support.

(1) Note. Art in this class requires some structural modification to materials to adapt them for body support. The mere recitation of a support, wherein the novelty resides in a chemical composition for the support, would not suffice for inclusion in this class; it would place the application in the appropriate composition art area.
