A multi-talent with many extras – the models of program S 170 are designed as A-stackers, allowing the safe vertical stacking of many chairs thus reducing the storage space required. Easy stacking, transport, and storage – an especially important issue for all multifunctional spaces. The shells of the armchair are made of plastic in dark gray, telegray or signal white, or molded plywood stained beech, without upholstery or with partial upholstery for seat. The molded plywood version is available with different backrest heights. Armrests made of elastomer.
