Operating instructions for your Svenstol®

The complete guide

The right ergonomic settings for your chair will make you more relaxed as you work and prevent discomfort in the long term. Our tip: make the adjustments from the bottom upwards – starting with the seat height.

Adjusting the seat height correctly

The seat height is correctly adjusted when your thigh forms a line sloping down to the knee. The angle between your back and thigh should be 110-120 degrees (open seat angle).
Important:
Your back should always be in contact with the backrest.
Frequent errors:
Seat height too high - you lose contact with the floor and your muscles tense up.

Locking and weight adjustment

Active sitting will help your concentration and prevent poor posture due to static sitting. Set the counter-pressure of the backrest to your weight so that when you are sitting upright you neither topple backwards nor have to apply too much pressure when you lean against it – the backrest must give you pleasant support with the counter-pressure set correctly.

Set the seat angle correctly

Lean forward with the seat, lighten the load on the discs in your spine. The angled seat is also essential for active sitting.

Lumbar support (pneumatic)

Use the lumbar support to set the curvature of the leaning surface. The curvature should be approximately level with the waistline (pelvic crest).

Lumbar support (mechanical)

Use the lumbar support to set the curvature of the leaning surface. The curvature should be approximately level with the waistline (pelvic crest).

Seat depth adjustment

With your pelvis back up against the backrest, you should be able to fit at least three fingers between the hollow of your knee and the front edge of the seat.
Frequent errors:
Too much seat depth - you automatically slide forward and lose contact with the backrest.
Not enough seat depth - insufficient support area, leading to muscle tension in the legs.

Backrest angle

By changing the backrest angle you can switch quickly from the upright to a relaxed sitting position and back again. In the relaxed position there will be less load on your spinal discs.

Folding armrest

Your shoulders should be more or less horizontal while your forearms lie on the armrests. Your shoulder and neck muscles should be as relaxed as possible.
Frequent errors:
Armrests too high - you cramp up and your muscles can even become shorter over time.
Armrests loo low - your arms pull your torso down, resulting in a hunched back and a stretched cervical spine.

Tip-up armrest (height adjustable)

Your shoulders should be more or less horizontal while your forearms lie on the armrests. Your shoulder and neck muscles should be relaxed as much as possible.
Frequent errors:
Armrests too high - you cramp up and your muscles can even become shorter over time.
Armrests loo low - your arms pull your torso down, resulting in a hunched back and a stretched cervical spine.

T armrest

Your shoulders should be more or less horizontal while your forearms lie on the armrests. Your shoulder and neck muscles should be relaxed as much as possible.
Frequent errors:
Armrests too high - you cramp up and your muscles can even become shorter over time.
Armrests loo low - your arms pull your torso down, resulting in a hunched back and a stretched cervical spine.

Comfort headrest

The headrest will ease the load on your neck and throat muscles.
