This is a very nice tower. It is fairly sturdy and is compact but offers a lot of area for cats to play. We have 2 older cats and a kitten and all love it. My only complaint is that I didnt realize it wont go flush up against a wall. The platforms stick out past the base in different ways which makes it more awkward that way. It isnt critical but sometimes you just need to put them there and thisnisnt a good candidate. Other than that its great!
