Sold per piece. The sofa covers are made from cotton fabric with a polyester filling, soft and smooth to the touch, and do not easily attract fur from hair or pets. Please follow our measuring guide and measure your furniture before ordering. Sold per piece, not as a set; suitable for standard sofas and loveseats. Multi-function and applications: This soft furniture cover protects your sofa, loveseat, armchair, and chairs from spills, stains, and pets. It is all-season and can be used beyond traditional sofa covers, including as a children's play mat, bedroom rug, padded mat, window sill mat, and more. Stay in place: A heavy, thick quilted sofa cover with a silicone backing provides a non-slip grip and stays put better than ordinary strap designs. Please note that small adjustments may be needed for very active dogs and children.
