Sitsack by James Van Vossel
The concept is based on the fact that you can't sit upright on a sitting bag, and you're not allowed to lie backwards on the 2 back legs of a chair. This combination creates a sitting sack in which you can put the upper part-which is connected to the sac- in the way you like: just shake the little balls to ad the right position.
