Overall the tree is well build. The materials feel nice and are sturdy as individual pieces. Only drawback is that it would be nice if the base had more weight to it. We’ve added 25lb of weight to it to offset the cats climbing up quickly/with any force. The cats meet the prescribed weight limit so the base actually being able to support on its own would be nice. Otherwise very nice product and would certainly recommend especially if your cats are well below the weight limit.
