SITTING POSITION AND SEAT HEIGHT
In the optimal sitting position the angle in your knees and between your
thighs and upper body is about 135 degrees and your heels are positioned
almost directly under your hip joints. In this position your pelvis will tilt
forward so that your lower back forms a natural curve, and your upper back
will straighten. Legs should be relaxed, not hanging in the air, and feet
should rest on the floor. Thighs should be relaxed against the chair, forming
a 90 degree angle relative to each other.
On the average, on a saddle chair one sits about 25–40 cm (10"–16")
higher than on a conventional chair. To find your optimal sitting position and
seat height, do the following: Raise the seat so high that your feet hang
in the air. Relax and let your thighs and pelvis stretch for 1–2 minutes. Let
gravity do the stretching for you. Then slowly lower the chair by lifting up
the height adjustment lever until your heels touch the floor.
In the right position the buttocks and the back edge of the chair are level with
each other. Sitting too far in the front diminishes both comfortability and sitting
health. In the right position the sitting bones settle to where the padding is the
thickest. Most of the weight of the person sitting is on the sitting bones.
TABLE AND MONITOR HEIGHT
Adjust the table so that your elbows are in a 90 degree angle.
The elbows rest relaxed on the pads on the table, next to your
body. Adjust the table a bit higher for passive visual tasks (e.g.
internet, reading) and a bit lower (3–4 cm) for active writing.
We recommend an electronically adjustable table that can be
brought up to the standing height as well. Learn more about
Salli's electronically adjustable tables at our website.
Pay also attention to the height of the monitors so that you don't
accidentally lower your head forward. The head weighs several
kilos and easily makes the neck muscles tense, disturbing the
circulation into the head. The brain doesn't get enough oxygen,
you get tired and get headaches.
MOVING AROUND WITH SALLI
You can easily move sideways by pushing with
one foot and pulling with the other. Make use of the
swing mechanism of Salli Light Swing, roll on the
chair to fetch things, walk while talking on the phone,
exercise for a couple of minutes, work standing at
times. Remember to take breaks!
Attention! Be careful not to place your toes under the
castors when you're using the chair.
The sitting position on Salli Saddle Chair differs from that on a conventional chair, and in the beginning your muscles
and tissues can get sore. The sitting bones carry the weight of the upper body, which might cause that area to feel
sore. Accustom your body to the new position in peace and increase daily sitting time little by little.
