How to use

Assemble the chair following the included instructions and use common tools as indicated. Adjust seat height so feet rest flat on the floor and knees form approximately a 90° angle. Set the backrest recline to a comfortable position and lock it if available. Configure the 3D armrests to match your desk height and forearm position: adjust height, forward/backward position and rotation to maintain neutral wrists. Regularly check fasteners for tightness and keep the mesh surface clean of dust.

Usage recommendations

For extended comfort, alternate between upright and slightly reclined backrest positions during long sessions. Combine correct seat height and armrest adjustment to reduce neck and shoulder tension. Clean mesh with a soft brush or vacuum and spot-clean upholstery with a damp cloth; avoid harsh chemicals. Observe the 125 kg maximum load limit and follow the manufacturer’s assembly and safety instructions to ensure safe use.
