He was clawing away at the rope-posts before I had it out of the box. Assembly was easy enough, though it took about a half hour all told to put it together, because it's huge! Great for a larger room with high ceilings, and excellent for cats who HAVE to be at eye level or higher at all times.

Thus far I'm quite satisfied with my purchase - especially for the price!

My only uncertainties: It's covered with a sort of fuzzy felt as opposed to carpet, so we'll see how long that lasts. There are also a couple of pedestals that are a little wobbly, as they have screws that go through and do not tighten all the way, so the pedestal turns sometimes. And lastly, the spaces in between parts are sort of small, so a bigger cat may have a hard time squeezing around if it's up against a wall (which you'll want for stability).
