I absolutely love this!! And the cats seem to also! It was easy to put together too. The instructions recommended using a screwdriver but if you have experience with power tools you can easily use them for the screws. Just be careful not to tighten them too much. It cut down on the time that it took to put it together.  The only cons to it was the weight dragging the box in the house and those little number stickers on the pieces. Some of the numbers were missing and the others were just a pain pealing off. But Im very satisfied with the end result and it looks very fashionable where its located.
