The Onyx Ergo Posture Chair is designed for office professionals and remote workers who spend extended hours at a desk and require significant ergonomic support. Its standout feature is the combination of a pump-up lumbar system and a seat slide function, allowing for highly personalized alignment that reduces strain throughout the workday. While its advanced adjustments provide superior comfort, the complex multi-lever mechanism may require a short learning curve for users unfamiliar with ergonomic chair configurations.

The Onyx Ergo Posture Chair features a base design compatible with armrests; please check your specific model kit to see if they were included in your configuration.
The chair uses high-resiliency contoured foam designed for long-term comfort and ergonomic support.
Yes, one of the three levers in the multi-function mechanism is dedicated to adjusting the seat pan angle.
Yes, it features a pump-up system that allows you to manually adjust the lumbar inflation level.
Typically managed via a lever under the seat, the seat slide allows you to push the seat pan forward or backward to set your ideal seat depth.
Use a vacuum with an upholstery attachment for regular cleaning and a water-based upholstery cleaner for spot cleaning, ensuring you blot the area dry.
Ensure the ratchet mechanism has fully engaged by pulling the backrest all the way up to reset the teeth before sliding it back down to your desired position.
Check that the tension knob under the seat is tightened sufficiently to match your body weight, and confirm that the tilt lock lever is fully disengaged.
Locate the pump bulb and press repeatedly until the desired firmness is achieved. If it loses pressure quickly, check the air valve release.
To assemble the chair, ensure all components are laid out on a soft surface to prevent scratching the black finish. Start by inserting the gas lift into the base, followed by attaching the seat mechanism to the bottom of the seat cushion using the provided hardware. Attach the backrest via the ratchet rail, ensuring it clicks into place securely.
For ongoing care, vacuum the upholstery regularly to remove dust particles that can wear down fabric fibers over time. If a spill occurs, use a mild fabric cleaner and a damp cloth, blotting rather than scrubbing to maintain the integrity of the foam. Check the tightness of all bolts every six months to ensure the structural integrity of the multi-function mechanism.
