This model focuses on posture-specific adjustments like lumbar, seat slide, and tilt; check your specific packaging to see if armrests were included as an add-on.
Yes, the multi-function mechanism allows you to lock the backrest at various angles within the 1-20 degree range.
The Onyx Ergo Posture Chair features high-quality, durable office fabric over contoured foam.
Use the designated lever typically located under the seat to release the seat pan, slide it to your preferred depth, and release the lever to lock it.
This is a standard height office chair. It works best with standard-height desks but may be too low for high-reaching standing desks.
Ensure you are lifting the backrest slowly through each click; if it passes the top, it will reset to the lowest position.
Check the connection bolts between the seat plate and the chair base to ensure they are fully tightened.
Press the pump repeatedly until you feel the internal bladder inflate; if it loses air quickly, ensure there are no obstructions in the valve.
To assemble the chair, ensure all components are laid out on a soft surface to avoid scratching the base. Attach the wheels to the star base, insert the gas lift, and secure the seat mechanism using the provided hardware. Ensure all levers are accessible on the right-hand side before final tightening. For care, vacuum the upholstery regularly to remove dust. If a spill occurs, blot with a damp cloth and mild soap; avoid harsh chemical cleaners which may degrade the contoured foam or fabric. Periodically check that all bolts remain tight every six months to ensure continued stability.
