The cat tree is exactly as I wanted. I modulated my way, and my cats are more than happy. It is easy to install, the instructions are very easy to understand picture. It is quite resistant, the cottages are strengthened, the hammocks are great ... Basically, brilliant! A very small downside is the little house down; which takes on a pole and suddenly is a bit shaky (hence my 4/5). But I am reinforced with a wire hanging behind the posts. I hope it will last long: D
