I saw another review that said it was difficult to put together with one person, but I didn't find that to be the case at all. I rested the top on a cushioned chair while putting on the hinges, no problem. I have this set up in my entry way and nobody can tell it's a litter box. The cats took to it right away and the amount of litter tracked outside the box is minimal. All in all, nice piece of furniture, not difficult to put together, and very useful. By the way, it comes with extra screws which was good because one of the screws I got had metal shavings in the top and I couldn't get the screwdriver in.
