Today, people spend over 6~8 hours a day on chair. Inevitably,
there are problems associated with the life pattern such as poor
blood circulation around pelvis, hemorrhoids, prostate disorder,
and corpulence of lower body. In case of severe hemorrhoids patients,
they have problem sitting in traditional chairs. Because of this
change in life pattern, people sitting on chairs are potential
Harachair is resolving and easing these problems by providing
a way to maintain proper posture and circulation. Hara chair has
changed the traditional single base and a back support structure.
Weight of the upper body is spread evenly on two bases and the
bases can be customized to fit and support pelvis of individuals.
Also the gap between the bases allows better air circulation and
helps blood circulation. These can prevent problems caused by
sitting in a chair for long period.
Harachair is designed with the concept of fitting the chair into
human body rather than demanding adjustment of human body to the
chair. A transition from static to dynamic design in the development
of chairs is necessary and Haratech is endeavoring to give people
with the best chairs.
base of a chair is separated in two and designed based on a human
body science to fit pelvic structure. The chair can be adjusted
to give comfort to the body.
genuine mechanism of Harachair allows easy adjustment of the base
of a chair to give comfort.Stable and comfort posture helps preventing
spinal and pelvic disorders as well as hemorrhoids.
base of Harachair moved vertically to fit the pelvic structure
of a person. The base can adjust itself to fit the ideal pelvic
angle for men and women. This relieves the pressure on spine and
pelvis caused by the upper body weight and enables better blood
use of a high grade gas cylinder makes it easy to control the
height of the chair.
of the chair can adjust the height to relieve the strain on the
wrists and arms. Also the use of foamed polyurethane gives sturdy
and stable support.
back support and headrest can be adjusted to fit your preference.
The back support has 5 different modes to give a comfort.
removable headrest is designed to give the best support to the
neck and the height and angle is adjustable to match your needs.
When growing up, many people are told to have proper posture.
People emphasize the importance of keeping the right posture but
fail to think about the reason for not doing so. One of the main
reasons is that traditional chair design is not adequate for everyone.
Angle of pelvis is different from men to women (65' for men and
85' for women). Also the size of each individual varies. Therefore,
adjusting the chair to fit each individual is necessary.
The average human nowadays spends most of time on a chair. According
to a study, Average high-school students spend 10~15 hours on
chairs and office workers 6~7 hours.
Spending long period on chair could result in the followings:
- pelvic misalignment causing spinal problem and corpulence of lower body
- twisted spines causing migraine headache
- disorder around anal area
These problems could occur due to improper distribution of upper body weight. When you sit on an ergonomic chair, 50% of your body weight is focused on an 8% of a touching surface area around hip bone. That is, your weight is focused on two points (one on each side of pelvis). Therefore, pelvis is an important bone which supports the body weight when you sit and it is important to support the pelvis properly.
To resolve these issues Haratech has developed Harachair with
the following approaches.
Hara ergonomic chair:
1. Defines a new relationship between a human body and a chair
through a dynamic human model focusing on pelvis shape
2. Considers human body according to measured data
3. Pays attention to the distribution of bodily pressure on the
chair and body's sensing it
4. Adapts conditions such that gives least stress to body based
on studies of body posture and muscle activity
5. Utilizes the body movement to design the shape of ergonomic chair
The main innovation of Harahair is redefining the idea for a
base. With the above considerations, the base has been divided
into two pieces and each part can be adjusted to give the suitable
support for pelvis.
