All elements in the collection may be associated with two characteristic mechanisms that guarantee an absolute variation of the “comfort system”. The first allows height variation of the back cushions via rotation of the rear brackets to a vertical or horizontal position, thanks to a novel and exclusive patented mechanism. The second involves the seat, which may be slid forwards, thus increasing the usable depth and offering complete distension of the body. All the frames are in metal and guaranteed for 10 years. The padding is in contour density polyurethane and the cushions filled with goose feather. All elements have fully removable covers.
