I purchased this bag for my child who's complaining of carrying backpack to school. This is a really great backpack. It looks sturdy. (Let's hope it last!!) Package came in box, and the bottom is un-assemble. It comes with instructions as well. You have to push down the 2 small thing behind the backpack for it to stay stand ( see pic. #2 and #3). I like that it has 3 zipper compartment to put all the kids school belongings. The last zipper is where the laptop compartment. It is padded, which is great. The zipper seems to be okay, but I would not say that it is a heavy duty zipper. Overall, this is an excellent bag for kids.
