Perfect for outdoors or the porch. Water passes right through, and after a rain shower or cleaning with a hose it dries fast and will not mold or mildew. The construction is similar to that of a high-quality outdoor chair cushion. The cover is made of upholstery-grade outdoor acrylic fabric, and the inner stuffing is bonded polyester fiber, neither of which will absorb water or odors. The inner stuffing will not clump or break down. Bed height: 4". USA.
