Tsinghua University furniture design graduate Yuming Hu has created a range of chairs designed for the peculiar behaviours of different users.
Focusing on the micro-movements people make after they sit down, Hu aimed to create a range or chairs that focus on the subtleties of body language and gesture rather than big movements.

"Micro-movement has always been studied as an important part of psychology. However, it is not specifically mentioned and applied in the design of the seat," explained Hu.
Hu, a recent graduate from the Department of Environmental Art Design at Tsinghua University in Beijing, noticed that most chairs are designed under the guidance of ergonomics. He concluded that this only meets the basic need for the body. Designing for "sitting behaviour" could lead to much more specific design.
Hu looked individually at the way people moved their upper limbs, hands, lower limbs, feet and torso when sitting and designed a set of six chairs that aim to satisfy these movements.
One chair, which features a large outer circle, allows a user to reach up with their arms and stretch by grabbing hold of two smaller rings. This shape came from an observation that the seated body often requires a good, deliberate stretching.

Another chair has arms that extend vertically outwards to allow the user to occupy space beyond the seat itself, while a third chair is designed to rock forwards to help the user stand up from a work desk when the weight of the b...
