Quite sturdy, cats love it. They still roam the high shelves though. The hammock seems useless, but others might like it. Doesn't easily fit in a corner, but with some adjustment it will. Nice scratching spots all over. Cats still scratch at rugs and chair seat pads, yet. During the real hot weather the cats wouldn't go near it, but when it is cooler they love it. Long rope came loose, but some Gorilla Glue took care of that. It may have to be attached to something, when the cats get bigger as it is swaying a little, when they wrestle on it.
