My big 20lb cat has super enjoyed this tree. The levels are big enough he comfortably relaxes or plays without falling out. He made himself at home seconds after I got it out of the box. It’s solid so doesn’t tip or lean. Easy one piece to assemble. The top piece moved a bit when he jumped on it so I re-positioned it with that top level against the wall. Perfect. There were lots of bits of carpet strands to trim. Easy to solve with a pair of scissors. He now happily supervises all in his kingdom. Money well spent.
