I've bought two other beds for my small dog, and this one was a bit more challenging to assemble due to a dented end. It wasn't too bad, but it did require some effort. I had a male friend rush the assembly, and later it ended up breaking when my friend reinforced and balanced it. I believe a 100% metal frame is the way to go for these dog beds, regardless of the dog's size or the cot. I have been trying to repair it with layers of gorilla glue, but it broke again during testing. However, I'm not worried because I enjoy making things and I'm quite handy. I plan to replace all four corners with metal or PVC corner "pipes," so my dog can enjoy it for years to come. The bed is nice and big, but the fabric may get hot, although it doesn't indicate that in the description. I'm basing this on my own skin sensitivities rather than my hairy boy, Tesla. Little Bear loved it, even with the broken corner. He didn't mind and laid on it at an angle, as if to say, "What broken corner?" If I remember, I'll post an update after reinforcing it. Just remember, balance is KEY when setting these beds up.
