This is a 3-week project to design a task chair, which is free to the area of chair in aesthetics, form and use. Thinking the advantage for users and find a unique solution that encourages good sitting behaviors.

Research

Most girls like flexible posture, they want to put their feet and leg on the chair. Uncomfortable chairs typically put adverse pressure on some part of the body or require excessive muscular work in order to sit.

This can cause soreness and encourage the sitter to adopt slouched postures that restrict circulation, impede respiratory and intestinal function, and lead to musculoskeletal injuries. When people sit on a chair, they want to put their feet higher that allows people feel comfortable with changing more flexible pose.

Seating Poseture

Principles of forward tilt:

Thigh-torso angle is opened to an ‘ideal’ 135 degrees

Muscles of the lower back, pelvis and thighs are in balance

Promotes natural lordosis

Provides conditions for enhanced breathing.

As a industrial designer, he knows the multifaceted nature of orchestral seating design better than most.

Concept

The purpose of the chair is to find a best solution allowing people can put their feet on chair.

Development

The face of seat is slightly curved to match the foot.

In the development of full-size cardboard study models, seat panels are made several to test the feet position and comfort level.Legs are cut several to test for the seat panel and test the intensity and aesthetic appearance.

Development

The marriage of equalizing balance and tilt in a single seat form - where the advantages of the conventional seat area are combined with the angular benefit of a forward-tilt platform. The term equality is coined to define this principle.

Leisure TimeDevelopment

With Gearóid moderation over the quick task chair design, the ability was improved upon to design rapidly. This is a 4-week short project to finish a chair, time schedule is very important. It was a great experience to see his research on posture influence the development of this chair. Also, this is a new challenge that are free to the area of chair in aesthetics, form and use.

This is good change to have Gearóid here to teach how to build a right seat based on seating posture with nice finish and craft.

In addition, there were several design details and solutions that changed during the construction of the full-size. Several decisions were made during this process, which was a balance of form and structure.
