Bought two of these. One for my new kittens and another for my other adult cat. It's decently a good height but the platform's are small. Pictures make it look bigger. It will work for the kittens as it already has but waaaaay to small for my adult cat. He jumps on it and it topples over, he can't even find a spot to try and make use of it. It's easy to assemble, took me 15 min. The top has 3 dangle mice to attach, these come off. I ended up using my glue gun to hold them in place, so far it's ok but I can tell the glue is not going to hold much longer and will have to do it again. For the price I'm good with the purchase and the fact the kittens can use it. Had I needed for the older cat, I would have returned!
