Most people who sit in chairs with regular backrests and work for a long time have a very hard time maintaining an "straight back" position, becoming more and more of a bent position and finally a lower body going under the desk.

Instead of the backrest, the Hara Chair has only a lumbar spine to combine with the pressure dispersion mechanism on the separation seat to maximize the effect of suppressing the bent posture. 

The patented lumbar support system protects the waist by supporting the waist once more.

In addition, it is a functional chair for waist pelvic protection that creates a correct posture suitable for the user's body with a separate seat surface, a patented technology unique to Hara Chair.
