Product is well made and very sturdy. It was easy to assemble and the fit and finish was very good. However, this is not really a cat tree, it's more in lines with a kitten tree. I checked the specs of all the other trees on the site and found this one to have the best ergonomics for a cat and be sized on the larger size. Our cat is approx. 12 lbs and the tree is too small. The top perch is 12" diameter; what full grown cat can fit on anything less than 16"? I combined pieces from our old tree with this one to make a usable tree. The posts were also a bit on the narrow side but workable for an adult cat. Basically, the folks who design these trees have never owned cats or the cats where they live (China?) cats are a complete different size. It really shouldn't be rocket science to string together a few platforms on scratching posts; I think I will just make my own cat tree next time.
