I needed a cat tree that would be window height. This one is almost tall enough. I like the size of the platforms for the cat I bought it for (13 pounds). She didn't jump on it for a few days (maybe something about the way it smelled? She didn't say.), but is now sleeping happily on the top perch. I do continue to wish that more cat tree makers made bigger platforms (22 inches + length/ 18 inch width) for long and/or large cats and trees for older cats that are easier for them to use.
