Our Smart Pet Beds have been designed to bring comfort and joint support to your pet. We use the highest quality memory foam and include a very durable, inner vinyl lining to protect the inner memory foam from moisture. All our beds are covered with the highest quality fabrics on the market. Our fabrics are stain resistant, mildew resistant chlorine tolerant and will not fade from direct sunlight for five years. Our convenent zipper design allows for easy removal of the fabric cover for washing and drying.
