This is the most comfortable bed for my doggie. He LOVES it! I love the fact that the cover comes off and is machine washable. The inside with the shredded memory foam has its own sewn cover like a bed pillow. I had to wash it once so far and it still looks like it's brand new. I highly recommend this bed for any dog or cat especially if they have any joint problems. I see my doggie sleeping on his back, belly up and all stretched out as if he were laying on a cloud.
