Craftsman-built frames are constructed using solid, reinforced hardwood for lasting strength and stability. Frame support system features no-sag springs made from recycled steel. Seat cushions contain dense foam padded with a blend of sterilized down and feathers. Backrests are filled with a plush blend of poly fiber, sterilized down, and feathers, and back frame system is supported by flexible elastic webbing. Back pillows are abundantly stuffed and encased in down-proof covers. Coburn sectionals do not include metal connectors. Adding them is not recommended, as this will void our Warranty. The Coburn Collection is available in multiple pieces and customizable fabrics. Call, email, or live chat with our Design Team to create your own Coburn. We want you to love your Coburn as much as we do. We recommend ordering a fabric swatch prior to purchase, ensuring the perfect color choice
