Bought this because we are selling our house and didn't want a litter box out where buyers could see it. It is very nice looking, and you would never know it wasn't a piece of furniture. My husband assembled it when I wasn't home, so I can't comment on that. The unit is very sturdy and very large. We took out the partition after a couple of weeks because one of our cats was missing the box. Only a small litter box fits with the partition in. With partition out, we fit the largest cat box that I could find, with the highest sides, inside. The cat box is great, but now the cats have to scramble through the opening, over the high side of the cat box. I do with the entry was a 1-2 inches taller. Mostly it's a problem with the litter box, though. Overall, very happy with this product.
