The body wants to move

When a single seated posture is maintained for too long, the lack of movement can cause restrictions, decreased function, and possible pain.

Men and women sit on different planes.

Keilhauer observed gender differences in pelvic rotation and trunk flexion, which have significant implications in the design of task chairs suitable for both sexes.

The result: A chair seat and back shape that provides equal opportunity comfort.

Important innovations equip Keilhauer chairs with Pelvic Balance Point® technology to provide support for the distinct sitting styles of both men and women.
T1-L5 Free Shoulders® provides secure thoracic and lumbar spine support, which allows the body to relax, disengage supporting muscles, and increase circulation and oxygenation to the spine and brain.

Why don't people sit the way they are supposed to?

Years of research and training have produced ergonomic manuals advocating an upright seated position. Yet, in workplace after workplace, we observed men reclined under their keyboards, and women perched on the front edge of their seats.


What every body knows

Keilhauer and the Austrian design team EOOS set out to create an "intuitive" task chair that would follow the human body's natural inclination for movement and postural variation.
