I re-figured out all my angles according to the design tweaking I did and now have finalised the flat design to go onto my xanita. Finally. Here it is....

folding methods
I will also use the 45 degrees angles inside the x board to create my corners. These degrees may need to variate to accomodate my unique angles for the triangular arms.
refinement
From my last 1:1 model I worked out a few things. The first being that as it stands the seat doesn't feel quite wide enough to sit on (currently 400mm). The second being that the angles of the arms don't quite work. Both of these things can be fixed easily. I will pull the edges of the seat out further and create a locking system under the seat system then make the seat itself slightly wider to make it more comfortable. I will then re-calculate the angles and sides of the triangles that make up the arms.
The next thing I will need to work on is the folds in the x-board so that they all fit and fix properly.
1:1
I made another 1:1 model out of one big piece of card. This made it easy to see how the folding chair would work. The angles were calculated using trigonometry. When folded together the arms still didnt fit together quite right but i think I just did the angles on the opposite side of the protractor. This can be easily fixed and I will draw up a new flat pack plan according to these angles.
refinement
I revisited the layout of my flat plan and re-organised it so that the seat and extra support folds from the top of the plan. The arms still fold down from the edge and should slot into the seat area. I want to cut all the joins on the inside of the chair to keep it clean and neat on the outside.
When I made my first 1:1 mock up the cardboard folded in at the front where it wasn't supposed to. At first I was annoyed as it didn't look the way I intended but then the folds grew on me. This flat pattern incorporates those additional folds.
refinement
From my 1:1 mock up I realised some big problems with the workings out of angles and how they translate onto the flat pack. I am determined to get these right as there would be nothing worse than cutting out the x-board only to find it doesn't fit together properly. For this reason I set about re-learning Pythagorus and encountered my worst nightmare.
There are not words to explain the intense frustration these sums caused me. I did however work out the angles of the triangles that make up my arms of the chair. I think.
refinement
I decided to refine my fourth concept as it fits onto the 1800 x 1200 and can be constructed from one piece. The angles for the arms will take some serious calculations but I think I am up for it. This design is visually pleasing from all angles and invites the person to sit. This is my 1:1 mock up of the design.
design
My stool will be designed to cater for those having a quick bite or drink in the design area of 100% design tokyo. It will need to be 450 mm high (seat height) and hold 150kg.
The design should act as a perch rather than a lounge as the organisers of 100 % don't want people spending all their time at in this area. It should be comfortable enough to have a quick rest but not tooo comfortable so that the visitors spend too much time there.

Concept three
The slight slope in the seat on this stool directs the user how they are meant to sit on it. This chair is a 2 bit system that slots together.
Concept two
This concept is quite similar to my first concept but it is folded in a way that makes it stronger and easier for quick fold and take away with you.
