This is my second tree and replaces the one my cats loved to death for 3 years. (The old one is still fine but now too ugly for my den.) It's structurally very sound and stable, despite being a lot lighter than it looks (and thus easy to move). The brown fur is very inviting, and there are plenty of nooks and crannies for hiding and observing. The only problem is one small part was missing from the box we received, but my husband cannibalized the old tree for it.
