I had been eyeing this tree for months, attracted to the uniqueness and more classy take on your typical cat tree/condo and finally nabbed it when it went on sale for Way Day. Unfortunately, I was ultimately disappointed by its stability or lack there of. While for many cats this tree could be stable enough especially when placed strategically (between a couch and a wall for example), but alas, my cat has a wild streak in her and I didn't want to risk one of her bounding leaps to come at the cost of one of her three remaining "lives". The entire tree is quite large and heavy, and while I wouldn't say it is top-heavy, if the base was a bit heavier I think it would be more structurally sound. Returned :(
