My second concept was really an idea which i stumbled across from just sketching a playing with the card. I found that its quite supportive especially with the addition to the triangles within triangles, to resolve the problem of the seat lifting.
This design was by far the most easiest and simplest, it only consists of two triangles and just from this scaled model it seems to be quite strong, using an easy method to combine the two using slots, allowing it to easily be packed down and great to store.
