This tree looks nice, was sort of OK to put together but it is really wobbly.  I have two 8-9lb cats who love trees and scratching condos..but are very timid about getting  up on this tree because when they jump up on it it rocks.  We had to add additional braces for the shelves and make the bottom wider.  I'm not really happy about the quality.  Should be steadier to accommodate the design.  I'm sort of unhappy with the size of the top shelf/sleeper...could be bigger.
