Abstract
Abstract A seat comprising seating and backrest members mounted on a seat support structure. The seating and backrest members are molded plastic foam members lined with an upholstery material and including reinforcement and mounting frames which are foamed into the molded plastic members such that they are integral therewith. The support structure has mounting clips projecting into openings in the molded plastic members and engaging the reinforcement and mounting frames therein. With this arrangement the molded plastic members can be easily exchanged without the use of tools but they are, nevertheless, firmly held in position.
