Finding an elevated bed that fit a Vizsla and didn't overtake the room turned out to be a major undertaking. Most have outrigger legs that make them even bigger than the actual surface area, large sizes were bigger than needed, and next size down was inevitably too small. The medium of this Coolaroo is just right--big enough, with inline legs. It snapped together easily and solidly. My knock down to four stars is for the fabric itself. There's enough stretch that my mouthy pup's first attempt to chew the edge at one of the the 45deg cutout corners pulled it out of shape so that it's a constant temptation. The tag also begs to be chewed. I would wish for it to be printed on the frame rather than sewn onto the surface of the fabric. That said, the fabric is holding his weight (50-55lb), and he likes it enough that he's going there voluntarily, not just when sent to place. Size, comfort, plus the fact that I could get it in a wood-floor-decor-friendly brown make it a win.
I had this out together pretty quickly and my dog was sleeping on it within minutes.
