I wanted it to have a clean folded sides, and not showing much of the xanita corrugated parts.
The outer folds initial locking system from the concept 2 mock up doesn't seem to actually work, so i have to change the outer folds to interlock underneath the seat.
It worked, I'm glad I manage to execute the design in time and maintain it's aesthetic appearance from the original concept. Perhaps even better.
Hmmm.... I'm not sure if everyone can fit to sit on it, I hope Shin would as I'm designing for 100% Tokyo ;)
On the last day of consultation I managed to refine my concept into a promising locking system that might actually work. I still keep the side flanges of the chair to keep the characteristic of the design.
After figuring out the concept I realize that there are still enough material to add a higher backrest and also making the design more solid.
Last but not least, I finally satisfied with the design. It was quite challenging to build a chair that has multiple angular.
Especially on the major part as in the seat & side 
flanges.

I even tried modeling using solidworks, but the end result doesn't seem to look the way I wanted it to be.
I've tried dozens of locking system for my chair design but all of them seems to fail. The flaps on each site does not seem to interlock even with multiple jointings and the angles of the chair make it rather difficult to create a strong lock. It seems my chair was a bit to complex for my design capabilities. I should have stick to a more simpler concept......... Time is running out....tic tic tic..






Papton chair, I thinks it's the most brilliant folding technique out of all X-board chair design I would really love to produce something like this but it just seems that my technical imagination are not up to that level yet.... Perhaps someday,.. aite'
