My Needs...
Critical Dimensions
The dimensions of a basic chair suit me perfectly
Height from the floor:
it depends on the position in which I sit but in general I don't care
Depth of the seat: min 20 cm
Height of back support: min 15 cm for comfort
My dimensions
I tried different chairs
Research for a chair for flexibility, more specifically the split
NEED 1
Primary research, measurement of my legs as well as split in order to make the custom-made chair.
Research of chairs for flexibility existing on the market.
Chair for split
First sketches
First calculations of the measurements with the different sizes of wood.
Final 1: 5 scale drawings
Chair for split
Final Sketches
User Scenario
The user can adjust the size of their split according to their flexibility thanks to the movable “legs” of the chair.
They can thus put them inside the chair once the session is over so that the chair take up less space in the room.
A support is present for books, tablets...

Research for a chair suitable for scoliosis
NEED 2
Research of chairs for scoliosis existing on the market.

Sit well Chair
Final Sketches
User Scenario
Placing their knees on the chair in this way causes the user to sit with their back straight and thus relieves pain.

NEED 3
Research for a comfortable chair to spend hours at your desk
Good position to adopt at your desk
Research of chairs for office existing on the market.
Chair for sitting during hours
First sketches

Final Sketches
User Scenario
The user can add a tablet or not to put, for example, a keyboard, a meal, a notebook... and thus save space on their desk.

Chosen idea :
I decided to continue with the "Sit Well Chair" because it is the one I need the most and the design was the most interesting in my opinion.
The “Chair for Split” was pretty scary and didn't really help, it can easily be replaced by a rubber band.
The “Chair for sitting during hours” had a rather common design, quite basic and it did not inspire me in particular.
Sit well Chair
Further research
I chose the chair to relieve pain from scoliosis but still need it to be useful for working and drawing, which takes up part of my free time.
Two good solutions that can be applied to my design are:
Some of my last drawings
Different design tests to remove the "medical" aspect of the chair
In the end, after trying with full-size wooden sketch models, rounded designs are too complex to do with a saw and sandpaper, without using a machine, as the brief states.
I decided to go for more organic shapes
Sketch Models at real size
My design has to be personalized to the size of my knees / length of my legs, so I made real-size sketch models in cardboard to better visualize.
The chair, initially, was too low
I tested the strength of the chair by applying for 24 hours 1/5 of my weight on the 1; 5 scale sketch model in pine wood.

User Scenario
User Scenario
Final model, forcing the user to sit correctly and therefore relieves their back pain due to scoliosis.
In addition, the backrest can split in half and tilt more or less, because people with scoliosis have one side of their back that sticks out over the other.
The backrest can also be lowered thanks to a hinge system in order to use this chair as a small desk with a seat, this saves space, and helps with graphic work.
New Iterations
Changes to make the chair more solid by removing wood in some places to add some supports.
Final 1:5 scale model
I built a 1: 5 scale model to make sure the chair was working properly and that I liked the design.
CAD model
Placing all the screws in order to find a way to make the chair as solid as possible.
