Rio Sofa Bed's classic silhouette is wrapped in plush cushioning that pairs timeless appeal with enveloping comfort. A stowaway mattress makes hosting a breeze. The frame, cushions and pillows are made from natural materials like latex and wool. Our mattress is made from CertiPUR-US® polyurethane foam with protective layers of wool and a certified-organic cotton cover. This blended approach for materials delivers body-contouring support for pressure-free, luxurious comfort.
