Purchased this sandbox for my two kids because it came with a cover to keep neighborhood cats from using it and I liked the corner seats.  Took me about an hour to put together, very easy assembly.  I either missed it on the description or it didn't say but it comes with a thick piece of plastic for the bottom with holes in it for drainage.  Which was awesome because it meant I did not need to purchase anything to put on the bottom.  My girls, ages 3 and 5, have plenty of room and literally played in it all day when they first got it!  Cover is not blue....it was gray.

Pros: Excellent product for the money, smells good!
Cons: none
