How to Properly Adjust Your Office Chair?

Find out how to adjust your seat for optimum comfort

Did you know that 85% of occupational illnesses recorded in 2010 concerned musculo-skeletal disorders (MSDs) and low back pain? To prevent these problems and improve your comfort, it's essential to adapt your office chair to your body shape. A well-adjusted seat helps ease muscular tension, reduce lower back pain and prevent musculo-skeletal disorders.

Basic information about adjustments

To adjust your office chair correctly, here are the key points to bear in mind:

Find a comfortable sitting position

Back comfort

Seat height

Your seat should be adjusted so that your feet rest flat on the floor, at a 90° angle to your knees. This reduces the pressure on your legs and encourages blood circulation.

Seat depth

The seat depth should be adjusted so that the back of your thighs are comfortably supported, while leaving a gap of 2 to 3 cm between the edge of the seat and the back of your knees.

Backrest height

The backrest of your seat should offer the appropriate support for your spine. Adjust it to your body size for optimum support

Lower back support

Adjustable lower back support relieves tension in the lumbar region. Good lumbar support helps you maintain a natural posture and prevent lower back pain.

Neck comfort

Add a headrest option

For additional head and neck support, a headrest option can be added, depending on your chair model. This headrest can be adjusted in height or angle for maximum comfort.

Shoulder comfort

Opting for armrests

Armrests play an important role in shoulder and arm comfort. The following options are available:

• 1D armrests: height adjustment.
• 3D armrests: height, width and depth adjustable.
• 4D armrests: fully adjustable, with rotation to adapt perfectly to your movements.

Choosing the right EOL mechanism for made-to-measure comfort

The seat mechanism determines how your office chair behaves and adapts to your movements. Here are the different options:

Mechanisms	Descriptions	Advantages
Permanent contact	Back articulation system, independent of the seat: the seat back remains in constant contact with your back. This mechanism provides continued ergonomic support, while the seat remains fixed.	Consistent, ergonomic back support for greater comfort during movement
Tilting	The seat and backrest are synchronously tilted backwards at a constant angle.	Dynamic comfort, adapts to movement, easy to use
Centred tilting	The rotation point is in the centre of the seat, allowing a uniform tilt	Even, balanced tilt, ideal for a relaxed posture
Forward axis tilt	The pivot point is closer to the front of the seat, offering a smoother movement	Greater flexibility of movement, improved comfort for more dynamic users
Synchronous	Synchronised tilting system for backrest and seat at different angles. It offers optimum support for your spine and pelvis, making it the most ergonomic solution.	Ideal support for optimal posture, and adjusts body position to prevent pain
Self-regulating	Automatic backrest tension adjustment	Automatic adjustment for personalised comfort
Comfort or lateral	The backrest tension can be adjusted using a knob on the front or side of the seat	Easy tension adjustment, so you can tailor the support to your needs

Ergo+	Like the ergonomic mechanism, offering greater ranges of adjustment and a negative seating position	Allows for a greater range of movement, ideal for dynamic, personalised comfort

Comfort in the workplace begins
