Very easily put together and stable. It is tall like I wanted and wide enough that it won't tip. The 'huts' on it are big enough for my biggest cat and they all love the platforms. Soft. warm material is snuggly for the cats as well. The two balls on ropes at the top didn't last longer than 24 hours before they were chewed off. but this is normal in my house because the one cat chews the strings, but the rope toy is strong and will last. The only possible suggestion is that the rope at the bottom of the tree be moved to the front instead of kept behind the lowest hut. Very pleased!
