Great product.  Easy to put together and very sturdy.  Only 5 steps and took about an hour.  As I was building my cat was all over it.  If you have a cat that loves to climb or get up high this is the best.  This is a great deal, you get alot for a low price, the best I've seen.  I checked both [...] and [...] and they have nothing that compares to this cat tower.
