Ergonomic office chair selection and adjustment guidelines

Proper selection and adjustment of ergonomic office chairs are essential to prevent work-related physical ailments. When purchasing, users should prioritize fit and functionality over aesthetics. Key considerations include ensuring the seat height allows feet to rest flat on the floor with knees at a 90-degree angle, and verifying that the seat depth provides two to five centimeters of space between the seat edge and the back of the knees to avoid pressure on the thighs.

Even with an ergonomic model, incorrect adjustments can lead to discomfort. Lumbar pain is often linked to poorly positioned lumbar support, while neck and shoulder tension frequently result from improperly adjusted armrests. To optimize health, experts recommend a specific adjustment sequence: setting seat height first, followed by pelvic position, lumbar support, armrests, and finally the headrest.
