my son put it together and he had no trouble. The trouble I'm having is getting my chats to play with it I put some catnip on it they've been on it once or twice but as of yet they're not crazy about it.I hope when it's more sunny out and the birds and squirrels outside of moving around that'll be more interested in climbing on it and see what's outside. I would say that this is a good thing for cats especially if you have big windows for them to look at us I would say that people should buy this.
