This is an original Bird lounge chair and coordinating ottoman, models 423LU/424YU, initially designed by Harry Bertoia for Knoll in 1952. This chair and ottoman were originally purchased in 1961, and we have all of the original paperwork for it. The design features a body that is formed from interlocking steel wire, and this bird has matching black fabric covers for both pieces. The upholstery was updated and replaced in 1981 and is also properly documented.

The chair measures 33 inches deep, 38.5 inches wide, and is 40.25 inches high. It has a seat height of 14.5 inches. The ottoman measures 17.25 inches deep, 23.5 inches wide, and is 14.5 inches high. The cover is coming a bit loose from frame on both sides, and there is some evident patina on the frame. There are a handful of small spots on the fabric, and some wear apparent on the arms. Overall, this important set is in good condition. Please see photos.
