This is a great product.  I have 4 lager cats(each cats is at least 15 lbs) and they love to play with the ropes and in the hide away boxes, and especially they like to sit on the tallest perch.  The only thing was that the measuring to the ceiling.  This tree won't work if your room is taller that 6 feet.  We had to use some other means to reach the rest of the way, since the room I put this in was 8 feet high.
