HaraTech offers the latest Chair Technology Worldwide

HaraTech Technology and Patents

HaraTech has spent more than 10 years working on the question

"How can chairs be made more functional and healthier for people?"
Traditional chairs are only made of three parts: the legs, the seat and the back. A standard seat does not distribute the whole upper-body weight effectively. This often results in circulatory problems in the pelvic area and pain in the spine. This is what led HaraTech to use the latest scientific findings to create a chair with a double seat. HaraTech’s patented Original Mechanism distributes the upper-body weight effectively. This produces a general reduction in the pressure on the pelvis and spine and a significant improvement in the circulation in the pelvic area and spine.

Performance Benefits

Whatever you imagined a perfect chair should deliver, productivity, high style, environmental performance, HaraTech has the right answer for you.

Hara System 1

The base of a Hara chair is separated in two and designed based on human body science to fit pelvic structure. The Hara chair can be adjusted to give the best comfort to the body.

Hara System 2

The unique Hara chair mechanism of Hara chair allows easy adjustment of the base of a Hara chair to give comfort. Stable and comfort posture helps prevent spinal and pelvic disorders as well as haemorrhoids.

Hara System 3

The base of the Hara chair moves vertically to fit the pelvic structure of a person. The Hara chair base can adjust itself to fit the ideal pelvic angle for men and women. This relieves the pressure on the spine and pelvis caused by the upper body weight and enables better blood circulation.

Three Back ™

The Hara chair’s back changes shape to support the entire spine. This can reduce the chance of lower back sag and a hunched posture, which weakens disc walls, stresses back ligaments and causes deterioration of the spine.

Thermal Comfort

Thanks to slats in both its back and seat, and the special foam it uses, the Hara chair offers superb breathability. It effectively controls a balance of heat and moisture so users stay comfortable.

Adjustable Seat Depth

People don’t fit neatly into three average sizes. Leg and torso lengths can vary independent on a person’s overall height. Adjustable seat depth accommodates different body shapes for long-term comfort.

Seat Edge Angle Control

Enables people to ease pressure on thighs and widen the angle between legs and torso without feeling like they’re sliding out of their chair. Plus, shorter people gain nearly two inches of seat height.

Oversized Casters

50 millimetres casters are standard on Hara chairs, so the chairs move easily, an important feature in a time when nearly everyone seems to be in near constant motion.
