Presented for your consideration is a Vintage Mid Century Industrial Goodform Aluminum Desk Chair Propeller Base. Good condition chair with normal scuffing and scratching wear. Seat and back support covers are in fine shape with one small tears. See the picture Chair swivels easily but was unable to raise or lower it using the mechanism below seat. Appears to have heavy sediment build up and possibly rusted inner portions. Wheel rollers are all intact and work well. Not sure if these are original to the chair or were added later. Dimensions 30“tall Seat 15 x 14 thank you for looking
