It was quite easy to assemble, I definitely recommend using a power drill instead of a screwdriver. 1 piece came slightly damage in the corners, but it was the back piece so nothing too major. There was also no odd smell to the wood. Looks really good, and I'm happy I can fit 2 liter boxes. The downside is that the magnets that keep the doors closed are not very strong, so my cats will easily open the doors from the inside.
