Was impressed with the ease of setup and the size of the overall tree. I read reviews on almost every tree out there before deciding on this one. I have 6 cats, two who are both extremely large, 12 pounds plus, and the others average 5 to 7 pounds. Ty, one of my large boys barely gets off of it. He has no problem laying on any of the shelves or getting into the caves. Have had multiple cats on it many times and has proven to be extremely sturdy. Also have to say, this is one of my first purchases with wayfair and am extremely happy with the ordering process, the items I have received and the shipping was very fast. Will be ordering more
