A rare and substantial <PERSON> for Knoll 'Grasshopper' armchair deigned in 1946. This piece retains its original--and very durable--oil cloth upholstery to seat and back, along with its original finish on wooden frame--overall the chair remains in excellent condition for its age. Bent-laminated birch frame featuring signature 'grasshopper' arm rests give the chair a dynamic and inviting expression--armrests also provide strong support while sitting or standing up out of this chair. The frame also has an interesting construction detail where the back legs ``double-up'' as they're joined to the angled arms which rise from the legs, flanking the seat, to take their final position alongside the sitter's abdomen--a visually interesting and experimental application of bent-lamination technology. Curved backrest is decorated with round metal studs on its backside--a humorous detail that adds playfulness to the piece. Great ergonomics, it's one of the more comfortable and relaxing chairs at this size--could be use as an easy or reading chair in a smaller library. This example remains in excellent vintage condition for its age--with no structural issues or damage to upholstery.
