You are sitting on a quality product from the company Dauphin. However, please note
that chairs can cause health problems if used incorrectly. With this in mind, use our
sitting tips and the functions built into your chair. By doing so, you will make a substantial,
personalcontribution to avoiding problems when sitting.
1. Sit well back in the seat and use the entire seat area as far as the backrest.
2. Adjust the seat height
➊
so that your thighs and lower legs together form an angle of at
least (though ideally more than) 90°. Your feet are then relaxed and flat on the floor.
Your elbows are resting on the desk top and there fore the weight is taken off your
shoulder muscles.
3. In order to achieve optimum support for your thighs, use the seat-depth adjustment
➋
where appropriate so that there is enough space for about two fingers up to the width
of a hand between the front edge of the seat and the back of the knee.
4. Adjust the height of the backrest
➌
or lumbar support
➍
(where the upholstery of the
backrest is thickest) so that the lumbar support is roughly positioned at the level of
your belt.
5. If you spend a lot of time working in the relaxed position we recommend a neckrest
➎
to support the neck muscles. Adjust the neckrest so that your head is neither
pushed forwards nor overstretched and is supported over its entire surface.
6. Activate the synchronised mechanism
➏
once the basic functions above have been
set. Change your upper-body posture as often as possible so that your muscles do
not become cramped (dynamic seated posture).
7. Adjust the
backrest tension
➐
so that the upper body is held upright but is not
pushed forwards.
8. Activate the seat-tilt adjustment
➑
, particularly for forward-seated postures. Observe
an opening angle of at least 90° (right angle) in the bend in your knees and arms as well
as in your hip joint.
9. Now adjust the height of the armrests
➒
so that your elbows rest on the desk and
your shoulder and neck muscles are relaxed (same height as the desk or keyboard).
Correct the seat height, if appropriate. Adjust the width of the armrests
➒
so that the
elbows are not pressed against the body.
10. Make use of all the possibilites that your chair offers. By doing so, you will make a
personal contribution to avoiding problems when sitting.
Congratulations!
