How to use

Adjust the seat height so your feet rest flat on the floor and your knees are approximately at a right angle. Sit with your back against the chair back to ensure the ergonomic profile supports your lumbar area.

For meetings or shared use, set the chair height to match the table surface for comfortable interaction.

Usage recommendations

For regular maintenance, check and tighten fastenings periodically and keep the chair clean according to the upholstery or surface material. Use the height adjustment within its intended range and avoid placing excessive load on armrests or the base. If used for extended periods, alternate posture and stand periodically to reduce prolonged static loading.
