This cat tree was a BIG hit with my two cats. It is well constructed and was simple to put together. They use the sisal scratching posts and leave my furniture unscathed. It is sturdy and they have used it daily since the last bolt was tightened up upon putting it together. The carpeting on the different levels was plush and still looks like new after vacuuming. They DO fight over who gets to sit in the top platform but always reach a compromise.  :)
