Knap Chair And Footstool By Pier Weiss. Heal's first introduced Scandinavian design to its customers in 1951 with 'Scandinavian Design For Living', an exhibition featuring furniture and home accessories from Scandinavia. Designed by Per Weiss, the Knap chair can be set in three different positions to allow for the design to be used as a chair or a footstool. This versatile piece complements the Knap sofabed perfectly as well as working as a stand alone chair. The main body consists of high quality pocket springs and foam that sits upon a stainless steel frame. Upholstered in a natural cotton cover with muted red, yellow, taupe and grey buttons. Elm tapered legs.
