The concept below was created from a single sheet of cardboard. The flat pattern can be arranged on the cardboard to accomodate one large bar stool and one lower stool of similar type. The concept is easy to put together as the furniture is of one piece and is pre scored for the ease of user build.

Structure:
When the product is folded to create the stool, running down the centre is an open pyrimid which stabalizes the stool. The "flaps" that are running from the triangles as seen on the flat pattern are positioned in a way that when folded seem to run into each other, thus creating this centre pyrimid.

The two other triangles, seen floating next to the flaps or "runners" tuck underneath the stools top, creating a stronger area where the user will exhaust most of their weight.

Aesthetics:
A unique approach to stability. The stool seems as though it is unbalanced given that the runner flaps are positioned on an angle to the x and y axis of the stool. Given this, the stool is very stable as the base of the pyrimid forms a square.
