Do you have a experience that you were so tired and beg for a place you can sit? Maybe you thought that you would bring a chair with you.
Now, this type of backpack can solve you problem. It is named Wear your seat and molded to fit you back. Wherever you go, you can carry your chair with you on your back. Although the idea is great, the bulkiness of the contraption scares me. In my opinion, it shall be improve on its appearance. Otherwise, it’s just a design that has no practicality for no people would like to make his butt look bigger.
