Tensegrity can exist in a vast array circumstances and shapes, but unless all lengths are equal it is considered irregular. To make a project that was equal I found 3 bike tires and a stainless steel double u frame. I wrapped the tires around the frame 4 times with 1 tire on each of the 3 sides. The result is a small ottoman that can also be used as a lightweight, portable seat. This design is one of my favorites and might inspire a new line of furniture.
