Each Costura seat has two back cushions, which are also reversible. The larger one is made of foam, and the smaller, softer one is filled with natural down. The chaise longue can be moved to either side of the sofa at any time. The covers are removable. Costura is a contemporary sofa whose design is grounded yet forward-looking. It offers a slim, space-saving structure, lightweight, cushion-like backrests, and exceptional comfort.
