I bought two of these beds three or four years ago for one of my dogs that had very short legs and severe arthritis. He was having trouble getting on and off of a soft cushy bed. The beds have held up well. My only complaint is that the cover, especially the bolster, is very hard to put back on the beds after they have been washed. I solved this problem by making super large 'pillow case' covers with Velcro closures that can be slipped off and on over the entire bed.
I never realized that dogs would care about having a bolster, but they always situate themselves so their head is on it. I've had these beds for over a year, and couldn't be happier with them. They are on a covered patio. I made a simple huge pillowcase with Velcro closure to cover them and keep them clean.
