This is the first cat tree I've ever purchased because it's the first cat we've ever owned. We have a feral cat who had kittens and were able to catch them all and give them away, but decided to keep one.
The item was so easy and fast to put together. 
Having a small kitten it's very difficult for him to get down from the platform above the room to that level, there isn't enough pounce room. But it fits perfect in an area that's all windows so he can enjoy it for years to come.
