Perfect if you have teeny petite cats. I have 2 15 lb'ers and they have pretty much destroyed it in just a few months. It's all rickety and bent and crooked.
And I don't know where you get this 106" fantasy. The top of the highest platform is 84". Even with the extension rod, i couldn't get it anywhere near my 9' ceiling without serious modifications and parts taken from their last tree.
Improve durability and I'll be a return customer.
