Both cats love it. I wasn't sure about its sturdiness, but our black cat is a big, solid boy and the tree doesn't budge when he's on it or jumps off of it. I plan to cut to fit carpet on the two levels that have no cushion, partly so kitties will have something to grip, and partly because I would have preferred a lighter wood color. 4 Stars because it came with a few nominal scratches. I built it alone and it didn't take long. Happy with my purchase.
