While there may be some sway when our 12 lb cat leaps from the couch to one of the many perches, this Cat Tree is very stable. Our kitty spends much of his day lounging on the various levels of the Cat Tree. He enjoys climbing and jumping on and off.  This Cat Tree perches and condos may not support a 180 lb person, but it should easily support two or three medium/large sized cats. Easy to assemble; I recommend assembly while mansion is laying on it's side.  A previous review was correct with the string ball coming undone. This does not seem to be of great importance to our kittty. "Fur" covering colors are compatible with our room decor. I would consider this a good value. Attractive, inexpensive, ease of assembly, fast and free shipping.....you can't go wrong! May NOT be a good purchase if you have a 2-4 y.o. child who likes to climb.
