Hi! (First official post, long time lurker.) I can't say enough about the Mammoth beds. I got Rosie one for Christmas and she loved it so much that I replaced her other bed with one. I have to bring down the second Mammoth bed when her bestie comes over (a Husky-Border mix) because she's also figured out that it's the most comfortable. I have the basic design, one oblong and one round. They spot clean beautifully. Rosie is a strong nester and there isn't a scratch on either bed. Oh, one was the ultrasuede or whatever it's called and the other is the plain canvas. Both equally durable. I am a very happy customer and have recommended them to friends, and they've also been happy. (No - not a paid endorsement - Rosie just really really likes her beds which makes me happy).
