I'd give this tree 10 stars if I could. It was put together in 15 minutes and is very sturdy. The cats were on it before I got the top box on. Most cat trees are covered with carpet and are hard to keep clean. And you never get the hair out of the corners of the platforms with sides. I cut up a rubber backed bathroom rug to put on the top platform and also had room on it for a bowl of dry cat food that the dogs can't reach. To cover the round platform I used a toilet lid cover which fit perfectly. Ok the bathroom looks a little bare now, but the foster cats are thrilled with their own spaces. And my husband hates those toilet lid covers anyway.
