Abstract
Abstract A seating construction with a seat and backrest wherein the seat is formed of a molded base member with a central recessed area filled with a soft resilient cushioning material. The base member is molded and formed of a generally non-deformable, relatively soft, foamed synthetic material, such as foamed polystyrene or foamed polyurethane. A lateral slot extends across a front portion of the upper surface of the base member and retains therein a nail-retaining block. Upholstery material is tacked to the nail-retaining block and drawn around the top front edge and front surface of the base member as a covering therefor. The backrest is similarly formed of a molded relatively soft nondeformable foamed synthetic material with a dished or recessed area in the front surface thereof filled with a soft resilient material such as foam rubber. A loose or bound back cushion desirably is provided in front of the backrest and a loose cushion is preferably provided over the seat portion.
