Love this cat tree. Our old one was covered with carpet and the platforms were pretty tiny. I like that most of the surfaces are removable so I can wash them. The top platform is a really good size...my girl can lay out comfortably. It's a much simpler, cleaner look. It was fairly easy to assemble...the hardest part was putting the cube together and that wasn't very hard. I can't really think of any negatives...at least, as of this review. I really love it and am happy with my purchase. Also, as with most things I order from Wayfair, I got it quickly and the price was great.
