Tired of the pet beds that easily tear, are difficult to clean and don't provide your pet the comfort they deserve? Dogbed4less offer the Best material for comfort, support, durability and easy to clean cover that blends in seamlessly to your home. Our pet bed products are 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 and weight. Unlike other lower cost multi-layer glued partial memory foam, we do not cut corners and only offer 3.2 lbs high density solid memory foam similar to high end human therapeutic mattress stores to promote better sleep and healthy joint. Our high density memory foam is 5 times denser and 4 times heavier than regular foams, which will not flatten overtime and provide many years of comfort and support. 2 excellent layers of fabric covers: Internal layer waterproof fabric zipper cover to help secure the pad and a durable 13 oz jean denim fabric zipper external cover (35"X20"X4" size) for easy cleaning. Our external denim cover is 100% cotton which is interchangeable for top or bottom side to benefit the pets that are allergic to synthetic fabrics. The external cover is machine washable and dry-able. Additional replacement cover, more sizes and colors are available here by clicking the Dogbed4less link on the top next to the title.
