Congratulations
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 å 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 therefore the weight is taken off your shoulder muscles.
3. In order to achieve optimum support for your thighs, use the seat-depth adjustment 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 backresté or lumbar supportè (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 headrest and
neckrestê 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 mechanismë 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 tensioní so that the upper body is held upright but is not pushed
forwards.
8. Activate the seat-tilt adjustmentì, 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 armrestsî 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 armrestsî 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.
