With its gentle sweep and excellent lumbar support comfort is paramount in the Bumper Chair’s deceptively simple nearly seam-free design. The arm cap and inner and outer shells are shaped from a single piece of upholstery creating a continuous uninterrupted welt around the seat. Originally introduced in 1964 the Bumper Chair’s robust portfolio of customization options includes numerous textiles and leather upholsteries as well as a series of bases making it the perfect chair for a variety of lounge living and work spaces.
