ABSTRACT:
A controlled deflection front lip arrangement is provided for seating, such as chairs and the like of the type having a base, and a seat with a rearward portion positioned to contact a buttock area of an adult user, and a forward portion positioned to contact a thigh area of the user. The rearward portion of the seat is attached to the base for support thereon. A spring connects the forward portion of the seat with the base in a manner such that body movement of a seated user deflects the forward portion of the seat upwardly and downwardly independently of the rearward portion of the seat to alleviate undesirable pressure at the thigh area of the user.
