Matthias Demacker created a family of seats to respond to domestic and contract requirements: high-quality materials, meticulous finish, generous proportions and versatility of coupling between the frame and seat. The formula is a stool with two-coloured or one-coloured Tech structural polyurethane seat upholstered and frame adjustable with a footrest on a chromed column and square base in satin steel. Available in two heights (h75 or h65).

Made in Italy
