My cats love this! Fairly easy to assemble (10 minutes). They have a great time playingclimbing, and once they calm down, napping inside. I love the design. Not your typical carpet-covered monstrosity, this actually looks good in the living room. There are 2 potential negatives (definitely not deal-breakers) , which caused me to give 4 instead of 5 stars 1. the product can be a bit unbalanced when 2 cat-nipped kitties are hurling themselves at it, 2. the tiny cushion inside was not substantial enough (easily fixed by removing that and replacing with another cat bed which I already owned). This is the cool cat tree I was looking for for my cool cats!
