I have a 3 level, grey, floor to ceiling cat tree that my cat has never used. Originally paid $90 for it 2 years ago. I think my cat has sat on it less then 15 minutes total in 2 years.
Max height is like 8'5".
I just dissembled it. Its going in the dumpster tomorrow unless someone contacts me to claim it first. I vacuumed it pretty good to get all the dust and cat hair off, its still in great condition. My cat never scratched on it.
Heres the actual amazon link for my exact model.

I can arrange for pickup at my home south of City Park or my work, at 70 and Ward.
