Folding 2D-surface into 3D-seat?


I’m working on creating a 3D-model of a chair for a friend. The idea is that the seat of the chair, made from plywood in the rough shape of an “A” laid flat, has its two legs pulled to eachother and joined, resulting in the shape of the seat. I’m wondering if there are any relevant components in GH or ways in Rhino of accomplishing this? I have designed the outline of the shape in GH and would like for the final shape to be parametrically designed.

I attached a small clip showing how the shape of the seat is procured.
