The Onyx Ergo Posture Chair is designed for office professionals and remote workers who require extensive daily support to maintain spinal health and focus. Its primary benefit is a highly customizable ergonomic interface that allows users to tailor the seat and backrest to their unique body proportions, though the assembly process requires significant attention to detail and patience to ensure all levers are correctly tensioned.

This model focuses primarily on back and seat depth ergonomics; please check your specific sub-model variant for integrated armrest features.
Use the dedicated seat slide lever, typically located under the right side of the seat pan, to push or pull the seat to your desired depth.
The Onyx Ergo Posture Chair is built for standard commercial use, generally supporting up to 120kg.
Yes, the multi-function mechanism allows for locking at various stages within the 1-20 degree range for the backrest.
Check that no packaging material is stuck in the mechanism and ensure the lever is not being obstructed by the seat fabric.
Ensure the tension control knob is tightened and the locking lever is fully engaged in its designated slot.
Locate the pump mechanism on the side or rear of the backrest and press firmly to inflate the bladder; check for air leaks if it fails to hold pressure.
Inspect the gas lift cylinder for debris; if it continues to fail, the cylinder may need to be replaced as it is a common wear component.
To assemble your Onyx Ergo Posture Chair, ensure all hardware is tightened firmly during the build, specifically the bolts connecting the mechanism to the seat base. For compatibility, ensure you have a workspace with enough clearance for a 360-degree rotation. For long-term care, vacuum the upholstery weekly to remove debris, and wipe the frame with a damp, soft cloth. Avoid using harsh chemicals on the fabric. Periodically (every 3-6 months), check the bolts for any loosening caused by daily weight shifts and re-tighten as necessary to ensure a silent, rattle-free experience.
