This is the second one of its kind that I purchased for my dogs. The first was similar but not from Wayfair. My dogs didnt like the first and didnt like this one either. It took a lot of strength to put it together but made it very secure and would seem that is would be durable enough for a heavy dog (I have yellow labs) to enjoy without it becoming rickety. I tried it on my deck and in the yard but they wouldnt go for it. A quality dog bed. Im still giving it 5 stars.
