Ideation Sketches
These Ideation Sketches explore different ergonomic chairs through cushions, form, armrests, and legs.
During the ideation sketch phase, I kept in mind rough ergonomic measurements such as the angle of the back seat for the most comfortable lounge chair, the length and width of the seat as well as the favorable height.
I explored sketches 4, 13, and 23 further below but the final design I went forward with, after a few changes, is on page 2, sketch 23



I chose three ideation sketches to move forward with and experimented with the side profile. In terms of ergonomic design, I researched the perfect angle of lounge chairs; beyond that, the experimentation of the legs was solely for aesthetics. The final design is page 3, design 23.2; top right.
