I ordered the bed in size SM for our 2 Chihuahuas and they both have in this size very much space. The cushion is very stable and the cover can be removed with a zipper and wash. The ring can be seen on the bottom of the bed. This ring has a very good level to cushion and our dogs lay there very much like their head off. The fabric is very soft. The bed is visually quite different times and like it very much. I would buy this bed again at any time.
