Harachair changed the traditional single base and a back-support structure. The base of a Harachair is separated into two components that are ergonomically designed to fit our body's pelvic structure.The ergonomic base design also allows better air circulation and promotes better blood circulation.

Harachair is designed based on the concept of letting human body comfortably rest on the chair, rather than forcibly adjusting the body posture due to chair's demanding structure.
