We've had 6 cat trees over the last couple of decades. They've all been sturdy and well loved. This one is no exception. It is replacing a 6 year old model. This tree is easy to assemble, and very stable. We have a 20 lb cat that hits it at a full run and launches himself to the top. Many inferior cat trees fell before him (actually...more like out from under him) until we found this 74" Cat Tree in Brown. He barely moves this one. Our cats range from 3 months to 19 years, and 2 pounds to over 20 pounds. As I write this there are 6 of them sleeping or playing on various levels of it. There's enough room for the other 3 to join them, and that was an important decision in choosing this particular model. Our aging kitties took right to the stairs & lower "den". Everyone loves it!
