The seat bottom frame includes first and second laterally-spaced seat bottom frame members extending from the seat back forward to a position adjacent the knee area of a seat occupant. A seat bottom diaphragm assembly is provided for attachment to the seat bottom frame for supporting a seat bottom cushion. The seat bottom diaphragm assembly comprises fore and aft brackets carried by each of the first and second seat bottom frame members, and fore and aft diaphragm stretcher bars extending laterally across the seat bottom for being locked into the fore and aft brackets of the first and second seat bottom frame members. A seat bottom diaphragm having fore and aft attachment members is provided for being quickly attached to and detached from respective fore and aft stretcher bars. The seat bottom diaphragm has an untensioned fore to aft dimension when not attached to the stretcher bars which is less than the distance between the fore and aft stretcher bars, and a tensioned fore to aft dimension when attached to the stretcher bars sufficient to provide adequate seat bottom support for the seat occupant.
