I bought this for my arthritic lab. The memory foam is very soft and molds around his body, but when it's time to stand up, there's no support from the bed to help him push up. It's harder for him than pushing himself up off of the bare floor. We are going back to an egg crate foam bed that he had much better results with. A soft, yet very dense foam works much better for him. Even my lab that isn't arthritic won't use it. I do love that the cover is waterproof. I am going to use the cover and purchase a separate piece of egg crate foam for the inside.
