Update on the work with the full scale physical prototype done. There is tendency for rotation of the tabletop that comes with material performance and the structural solution that needs to be overcome. The aim is to find a solution for this very soon, in order to move on to production issues. We are also considering to enter in the Asahikawa international furniture design competition, at the first stage this only requires visualizations.

rotational problems: overall rotation of tabletop potentially due to rotation of the joinins points between upper and lower leg and horizontal members

alternate solution 1
alternate solution 1: fixing the joint
alternate solution 2
alternate solution 2: fixing joint to triangle
alternate solution 3
alternate solution 3: inside band fixing joints
alternate solution 4: widening the connection by inserting wedges that makes the point of intersection between top and bottom part of leg and horizontal triangle "wider", thereby adding structure that limits horizontal rotation and torque.

alternate solution 5: "deep" triangular inside structure
alternate solution 5: "deep" triangular inside structure that stops horizontal members from torquing. Possibly the "cross" is enough to accomplish the same.
alternate solution 6: turning the vertical leg 90 degrees, which should make it stronger in the "rotational direction". When connected to the horizontal members, a box is created which further improves this
