My cat likes the height of this tree and jumped on it and settled in as soon as I put it together.  I really like the way it looks.  I would give it 5 stars except the tree shakes more than I would like when my cat jumps on it.  Also, it took awhile to figure out where and how some of the hardware in the predrilled spots go in but once I figured out the first ones then it was OK.  Everything fit together nicely except for the very top ledge - there's about a 1/4" gap but the ledge seems to be anchored enough.
