Comfy, modern lines meet stowaway mattress: make Rio Corner Sleeper Sectional your guest room in disguise! Its moderately deep frame allows plenty of room to curl up when the mattress is tucked away. 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.
