We got this set to fill in spaces for a larger wall-mounted set. I had to open the box immediately since it was soaked and not wrapped in plastic on the inside. Anyway Besides the packaging issue, my cats claimed the big shelf before it was even on the wall! It was easy to install and all 7 of my cats have taken turns climbing to the top for a cat nap. I am debating now on purchasing another set just so I have for future catification projects!
