The pleats chair

Lookingto both architecture and fashion when developing the design for the Pleats Chair

Self-initiated project

Category: Furniture Design

Year: 2018

The Pleats Chair is an aluminium chair that is lightweight and strong with a pleated structure. Corrugated structure is widely used in an architecture and a fashion in terms of the strong structure and the beautiful aesthetics.The Pleats Chair highlights both aspects with a carefully designed pleats pattern.


My first approach to this project was to develop a strong yet lightweight chair. Aluminium is not only a good material for it’s rigidity and lightness but also recycling. The energy to recycle the aluminum only requires 5% energy of producing the new aluminum. The recycled aluminium generally can save significant amount of the cost over the production of new aluminium, even after the cost of collection, separation and recycling are taken into account.


In order to achieve an elegant aesthetic, a custom-made two-part mold was designed with a pattern of the pleats. These pleats are pressed on to the aluminum sheets with a strong pressure to make the body of the Pleats Chair. The profile of the cross section continuous from the backrest to the seat smoothly with legs by sharing same radius. As a result, the thin shell of the body can stay rigid to seat on while maintaining a delicate aesthetic and a lightweight. The embossed pattern and the profile of the chair brings a unique character to the Pleated Chair.


Digital works

I have made just one prototype of the Pleats Chair, which is powder-coated in a vibrant yellow ochre shade. But I would like to also produce it in shades of green, red and blue.
