Exactly what I've been looking for at a great price! Most other places sell towers like this but use materials other than carpeting, which makes it more of a harder surface and not really useful for a cat to scratch. It's heavy duty and is great for a leg up to a higher spot for my older cat. The inside space is not fully carpeted around the sides and top, but I don't mind that since neither of my cats go in those spaces. You can easily attach some carpet remnant or other material inside there to remedy that if you want. I don't know of any manufacturer that actually completes the insides anyway, so it's not specific to this brand. I recommend getting one.
