Physics Professor
DUOREST® ergonomic chair is equipped with worldwide patented technology invented
by German Physics Professor, Dr. Matthias M. Brünig, who has revolutionized the way
we sit since 1988. DUOREST® dual backrest supports one’s back firmly without exerting
pressure on the spine and distribute the pressure to the left and right back muscles
effectively. The centre-pivot in between the dual backrest allows the backrest to swivel
in various directions as the user leans back and forth. This movement elevates the pelvis
and allows the waist to be embraced by the backrest. As a result, the pressure on the
lumbar vertebra is reduced by 50% as compared to conventional chairs.
An experience on a DUOREST® ergonomic chair is equivalent to a muscle relaxation
therapy. Besides alleviating fatigue, the dual backrest’s adaptability also creates a
massaging effect on the entire back musculature. The parameters of the DUOREST®
ergonomic chair can be varied to fit all body shapes and sizes. Medical experts
have advised that good posture and dynamic sitting promote good health, expand
concentration and improve productivity.

Importance of Proper Sitting Posture
Your Back Experience This Much of Pressure
The number of back-related injuries result from prolonged sitting
is on the rise. The prevalence of computer-related musculoskeletal
pain among office workers and students is also increasing.
The body exerts 100% of its weight on the
back when one is standing. However, it is no
less strenuous when one is sitting. The weight
load on the upper body when sitting down, is
1.5 times the weight exerted in a standing body
and 6 times the weight exerted on a person
who is lying down.
Contemporary chair designs should not only focus on appearances
but also on their ergonomic features, which in turn, provide
firm yet comfortable support for different postures. Choosing
conventional chairs based on affordability and appearances may
result in injuries on the spine and hips as shown in the picture
below.
Prolonged improper sitting posture causes
chronic back pain or spinal problems. To prevent backaches, keep
your spine in a S-like posture and sit deep inside the seat. It is
also important to place the heels flat on the floor with the knees
locked in right-angle. Considering the above-mentioned factors,
it is important to choose a good ergonomic chair that fits your
physique and promotes dynamic sitting.
