THE RESEARCH THAT ADVANCED OUR
THINKING OF HOW A CHAIR NEEDS TO
SUPPORT THE BODY LED TO:
FOUR KEY DISCOVERIES
The spine doesn’t move as a single unit.
When you recline, your upper spine moves
backward and your lower spine arches forward.
Each individual’s spinal motion is unique.
Even for people of identical size, age, and gender, each
spine moves differently.
The upper and lower back require different amounts
and types of support.
Your lower back requires firm, constant support while your
upper back requires more support as you recline.
Vision and reach impact your posture.
When you recline in traditional chairs, the distance between
you and your work can increase, which in turn can strain
your eyes, arms and neck.
THESE FOUR DISCOVERIES BECAME
