Did it happen to you to sit on a rotten log or wet stone at a camp fire, or just need an extra stool in front  of your desk? I know lotus posture hurts like hell and is not a solution. Neither tripod saddle stools.
Folding stool. Each leg segment is roughly half of the diagonals of the prism that bounds the stool. The legs are made from cast  7075 dark grey coated aluminum and are designed to save weight and material by using a truss triangles reinforcement structure. Folded size 75*75*350mm. Weight 800 grams.
The stool is held into position by turning a cam lock that forces the flat heads of the legs to press one against the other.
