Since the 1950s, Plastic Armchair's organically shaped seat shell has been combined with different bases and produced in its millions. Its current polypropylene version offers even greater comfort. PACC makes the Plastic Armchair into an office swivel chair. To complement the product line, Vitra is re-launching the fully-upholstered Plastic Armchair. The organically shaped upholstered shells are particularly comfortable and radiate a homely atmosphere. The Hopsak cover in 13 colours can be combined at will with the eight colours of the seat shell. Together with the base frames, this creates any number of individual possible combinations. The upholstery is fixed to the shell with black or white piping.
