Decent sized (height) cat tree, but I am actually quite disappointed. I have a 1 year old 10-12 pound Siamese cat and he's making this tree shake. I put it together, following the instructions and making sure everything was tightly secured. The platforms and supports are VERY thin cause the entire thing to shake the higher up he climbs. I am on the verge on returning it because I thought it would be much more sturdy for my cat. He's very active and I wanted something larger than his current tree for him to play on. This is my first Wayfair purchase and I am disappointed in the quality of this item.
