This was such a great value for the money.....very well constructed. No problem in putting it together.Lots of things for your cats to do.   Best of all....my two youngest cats LOVE it...Even my 20 lb cat has no trouble zipping around on it and there is no way he can tip it over. It's pretty heavy!. They rip roar on this cat tree every night. It's easy to clean...just vacuum it off and you are good to go.
