The bed comes with 1 external zippered canvas cover in black, 1 waterproof internal zippered cover and 1 solid 100% 4 inches gel cooling memory foam pad with total of 8" inches headrest on the side. Dogbed4less pet bed products made with high quality durable fabric and top rated memory foam to ensure the ultimate comfort and orthopedic support, which are rarely sold elsewhere due to the higher cost, labor & weight. Unlike other lower cost multi-layer partial memory foam products from other brands, we do not cut corner and only employ premium solid layer memory foam which are sold in high end therapeutic human mattress stores to promote better sleep, healthy joint and long lasting. Our high density memory foam is five times denser than regular foams, which will not flatten overtime and provide many years of comfort & support under normal use. The bed comes with 2 layers of fabric cover: removable external canvas zipper cover in black color + waterproof internal zipper cover for comfort, easy cleaning and maintain. We use higher quality fabric, durable zipper with eyelid sewing design plus extra stitching boasts lasting quality, wash after wash. Extra replacement covers in denim blue, denim brown, microsuede brown, microsuede gray color and more.
