My dogs instantly loved the one cot so much, I had to get another because they started to ignore their other beds and pile all on the cot. They have held up well, are well constructed, and they hold 2 of my 40 lbs dogs easily. It was easy to assemble and is fairly easy to take apart. 

I really have no complaints about these cots so far.  

Pros: Easy assembly, durable, my dogs loved them instantly.
Cons: None so far
