My two new 5-month-old kittens love this tower. It looks good in my living room and is sturdy enough for their enthusiastic romping. Like a previous reviewer, I also chose not to put the top tier on because they love lounging on top of the house (and now I have a replacement post and platform for when they eventually destroy the current one). It's just the right height for playing with them when they're on the top couple tiers. Overall, a great product, much better than I could have purchased in a pet store (which I then I would have had to find a way to get home).
