  • Chair with contoured seat
    Patent number: 4062589
    Abstract: A chair including a contoured seat supported within a boxlike base. The seat includes a peripheral tubular frame and flexible material covering the frame. The base includes a pair of spaced, upright side members having grooves formed in the counterfacing surfaces thereof to match the contour of the seat in edge profile. A pair of lateral spacer members are connected between the side members so the edges of the seat are captured in the grooves. The seat is thus suspended in the base to provide a comfortable, unobstructed sitting area.
