Final Product

The chair legs appear longer >> narrow camera angle ( I guess...)

Seat >> 30mm Tasmanian Oak

Legs >> 30mm dia Tasmanian Oak ( Danish Oil finish)

Back Rest >> 3 layer 1.5 mm Bending Plywood (Spray putty, sanded down to create (modern) rustic look)

Inspiration >>

Composition of intersecting basic geometric shapes in Zaha Hadid's Vitra fire station, interpreted into organic language of Frank Lloyd Wright's Guggenheim museum.

Basically, the seat comes in 3 main components >> Seat + Back rest + Legs 4X.

All of the components are removable, which will fit in 50 x 50 x 15 box.

Considering box size from the brief (50 x 50 x 50 cm), I decided to get the chair in to 2 components >> Back Rest + Seat with legs attached for the easy assembly.

Chair Prototype Build

First leg design (tapered + rounded)

Clamping 3 layers of plywood

I changed the seat design many times. Even after I cut the timber, I trimmed off the seat because it looked too big for the back rest.

The white patches are putty filled in the old holes for the legs.

Refined chair design without wooden cylinder to connect legs to the seat,

now legs are joined straight to the seat with allen head bolts.

Back Rest

Material:

3 layers of 1.5mm Bendy Ply

After the template was cut, first layer of plywood was bent using heat gun (which surprisingly easy), then before the second layer of plywood glued and clamped on to the first layer, it was cut into 4 parts to give more strength.

Then, the last layer was glued on to the second layer and later trimmed off.

Back rest template was cut using jigsaw (not very good idea) and cutter knife (better, but it took longer).

Concept Development

From three initial concepts, I chose the third concept because I am interested in doing some experimentation with bent plywood.
