Easy to put together, great quality, looks good, much cheaper then well known pets store version - which doesn’t look as good. My cat loves it, but probably would benefit from slightly wider platforms at the bottom or some type of ladder that you could add, as he’s getting on a bit, so a bit harder for him to get down. I’ve left the top bit off as too high for him, but the bed part still attaches to the next section. Very fast next day delivery service which was free. V.pleased
