Looks good, very easy to assembly.  BUT it is unstable, and the top two levels are very wobbly.  Because there is only one support for the two top levels, they shimmy and sway when the cat climbs up to them.  Needs to be against a wall for support.  My two cats, 9 lbs and 15 lbs, do like it, and were trying to play on it before we finished putting it together.  The big one doesn't like high places, but the smaller one loves the top level.
