Twice brings us two.....two different backrest positions, two different interpretations of comfort...from one single sofa. Piero Lissoni designed Twice for Living Divani wanting to offer a double view of what relaxation could be through one simple mechanism. Painted steel frame with cross-woven elastic straps. Back and armrests are in double-panelled poplar. Seat and backrest cushions are of sterilized quilted goose down. Removable leather or fabric upholstry. Mechanism which, with the help of a gas spring allows the backrest to be raised vertically and tilted.
