We'll see how this holds up over time. It is very nice looking, but was a real beast to put together. I had to use vise grips as some of the screw holes were cross threaded. 
I am glad I read the reviews before I assembled it -- you'll want to leave off that topmost platform and attach the bed there instead (it lines up) as there is no way a cat can get to the top otherwise.

Pros: Very attractive. Like the stained sisal.
Cons: Hard to put together. Top platform is not well designed and is almost inaccessible. Fake (plastic) vines were destroyed by my cats in about a week.
