Assembly instructions would have been helpful but we got it done without divorcing.  Cats cannot use the platform levels as configured to reach the upper levels nor is there no way down other than jumping which as they get older will be an issue.  Our one cat will launch from our bed to the upper levels but our other cat who is almost 30# cannot maneuver around very well amid the posts and lower levels. There is not enough purchase space on the platforms to enjoy the front cubby hole either.  It is compact width and depth wise tho' and is not an eyesore.  Our big guy retreats to the old beaten up tower which suits him better. The cubby hole has an area already "damaged" around the entrance ring but whatever.
