Materials and Construction

To create the tubular legs I have choosen stainless steel as my material. This is because it is relatively cheap but also strong and can with stand large amounts of weight.

I think that plywood would be a good material for the seat and back rest because it can be strong and it can be moulded easierly to create the bend in the centre of each piece. One option for finishes could be similar to the book stop above and leave the material on show.

As I have choosen to use plywood to make the seat and back rest I wanted to try and make it look less like a wood because to me wood isnt aggressive in fact its peacefull and organic. If I was to use a polyester lacquer to finish the material I could add a glossy effect and colour such as in my final renders or a black like in the paino above.

When constructing the chair and piecing together all the parts I would like to have groves pre cut into the wood which the metal would then slot into and be glued. This is shown in the render above. I think the glued approach would allow for clean lines and a quality looking product however if glue wasnt strong enough I could add screws to help with the strength of the fixings.

Intial Renders of my Final Design














Final Design Development

The biggest visual difference in the design here is the height of the back rest which I have almost halfed in size so it matches the base part better. Ive tryed to change the legs to so the seat slots into it and creates a nice curve at the front for comfort.

This page is all about changing the back rest so it is split in half but still supporting the back correctly once sat in.

The main change I made on this page is to change the connection from the back rest and the base by using two steal rod the same width as the legs.

Along the bottom of this page I have tryed to add a handle into the back rest to make the chair easier to move around but also I have looked at curving the front of the main seat to try and add comfort but keep the aggression.

Instead of curving the edges of the legs here I have tryed to add more aggression by flattening them off. I have also re designed the legs similiar to an older design so the seating position can be made aggressive. The back rest I have also played with taking more inspiration from a computer chair.

The first major thing I have done with this design is to put the legs seen in the design below on top of the chair instead and make them a stand out feature. On this page I have also played around with the shape of the legs mostly from orthographic drawings.

Theses are intial sketches from one of my orthographic drawings but trying to turn the flat image into a three dimentional  sketches with a focus on manufacture and making it more plausible to produce.

Intial Perspective Sketches from Othographic Drawings

Two perspective drawing’s taken from the side view drawing’s below.
The chair to the left is again taken from side views but on the right I have drawn legs which allow you to rock into a more aggressive or relaxing seating position depending on how you sit.
