All my cats LOVE this tree. They were clambering up on it before I even finished assembly. Which only took 30 minutes, for a girl. And that included carrying the pieces upstairs. And unlike other reviewers - the included pom pom toys are still intact three weeks later. I have another very similar cat tree that I got at Petco - this one seems better made and the cats seem to enjoy it more. I am thankful that the toys that were included are 'quiet' since the tree is in my bedroom. They get LOTS of play. Great value for the money. Your cats will love it. Only tip I can supply is that it's easier to put the platform and stalk on top of the condo first - then mount that entire assembly in one go. Otherwise you'll need a step ladder. You can use the included Allen wrench to line up the holes in the condo with those on the shelf, for the screws.
