Duorest Theory

DUOREST ergonomics chair is equipped with worldwide patented technology invented by German Physics Professor,
Dr. Matthias Brünig, who has revolutionized the way we sit since 1989.

MOST OUR LIFE, WE SPEND WITH CHAIRS WHEREVER WE ARE.

Most our life, we spend with chairs wherever we are. To avoid personal injury headache, low back pain and fatigue with many pressure by
the general chairs, Ergonomic environment adjusted workstation can improve comfort and reduce the risk of long term injury of your
healthy.

We apply for ergonomics to our all work environments, companies can have lots of experiences to affect various works benefits for our
active work and our most wellness. According to Many demonstrated reports, most employees have got positive reaction to this
demonstrated care for health yields a variety of benefits.

Ergonomics program can give many people who definitely need a significant factors in their life.

BRAIN AND OXYGEN FOR FUEL OF MEMORY

Our sitting in a proper posture can be affected to blood circulation. Ergonomic sitting is able to give human a significant increase in word
recall resulted from the inhalation of oxygen for 1 minute prior to hearing a world list. (Moss and Scholey, 1966)

Positron Emission Tomography (PET) is a technique used to investigate the functional activity of the brain. The PET technique allows doctors to study the normal processes of the brain (central nervous system) of normal individuals and patients with neurologic illnesses without physical / structural damage to the brain.

When a region of the brain is active, it uses more fuel in the form of oxygen and sugar (glucose). As the brain uses more fuel it produces
more waste products, carbon dioxide and water. Blood carries fuel to the brain and waste products away from the brain. As brain activity
increases blood flow to and from the area of activity increases also. Knowing these facts, researchers can use radioactive water (H215O)
and PET scans to observe what areas of the brain are receiving more blood flow.

MASSAGE EFFECT

DUOREST® dual backrests support one’s back firmly without exerting pressure on the spine and distribute the pressure to the left and right
back muscles effectively, by which DUOREST® split-back system creates a massaging effect on the entire back musculature, alleviating
fatigue. An experience on a DUOREST® ergonomic chair is equivalent to a muscle relaxation therapy. In order to understand the benefits

and effects of massage, it is important to consider how the body responds physiologically. Massage involves two types of responses for
mechanical responses as a result of pressure and movement as the soft tissues are manipulated reflex responses in which the nerves
respond to stimulation.

ERGONOMIC AND DYNAMIC SITTING

3-D movable connecting rubber equipped in DUOREST® split-back system allows the dual backrests to swivel in any direction as the user
leans on the backrest. This flexible movement at DUOREST® split-back system elevates the waist and enables its spine and muscles firmly
embraced by the backrests. As a result, the pressure on the lumbar vertebra is reduced by 30~50% as compared to conventional chairs.
Sitting balance control directly affects transfer performance

An appropriate sitting position is fundamental to providing a stable base of support for transfer activities. A sense of position in space is
another crucial factor when attempting a transfer. In addition, the ability to precisely and accurately control intentional movements of the
center of gravity in different directions is important.
