Advantages

The chair’s solid steel frame and Class 4 gas lift deliver structural stability and consistent height adjustment, while cold foam padding maintains comfort over long sessions and in warmer conditions. Large seat dimensions and a deep 56 cm seat depth offer generous support. 3D armrests, an adjustable backrest with a 90–125° reclining range and an integrated rocking mechanism (up to 14°) enable a wide range of ergonomic positions. The durable nylon base with 60 mm soft-coated castors ensures quiet movement on hard and soft floors.

How to use

Adjust the seat height using the gas lift lever so your feet rest flat on the floor and your knees form approximately a 90° angle. Use the 3D armrests to set arm height, width and angle for comfortable forearm support. Release the rocking mechanism to allow reclining up to 14° and set the backrest between 90° and 125° for upright work or relaxed leaning. Position the chair so the deepest part of the seat supports your thighs; re-check height and armrest settings after changing posture.

Usage recommendations

For prolonged sessions, periodically change posture and use the adjustable backrest to alternate between upright and reclined positions. Clean fabric and PU surfaces with a soft brush or damp cloth and avoid abrasive cleaners. Confirm caster suitability and floor protection for delicate surfaces; consider a desk mat if needed.
