Really, they limited their customer base by the weight limits, neither of mine would qualify. Besides soon there wouldn't be room for me to walk through the house. It looks neat but does any dog really want this?
My guess is that Sedona would do to that bed what she's done to every other bed we've gotten her (except for her crate, of course). That is, even though she's reliably house trained, she'd pee on it!!
It is pretty tricky getting out of it more than anything. This is at the indoor doggy park we went to all winter so it isn't something they get to do a lot.
