The Onyx Ergo Posture Chair is designed for office professionals and remote workers who require long-term ergonomic support during extended work sessions. Its primary benefit is the extensive adjustability of its asynchronous mechanism, which promotes healthy spinal alignment and personalized comfort through features like pump-up lumbar support and seat sliding. A notable caveat is that the chair's complex multi-lever system may require an initial learning period to configure correctly for individual body dimensions.

Yes, the chair includes a seat slide function that allows you to move the seat forward or backward to suit your leg length.
Use the triple lever system: one lever for height, one for the backrest angle, and one for the seat tilt tension.
Yes, it features a pump-up system that lets you adjust the firmness and depth of the lumbar support manually.
Use a vacuum with a soft brush attachment for routine cleaning, and a mild soap-and-water solution on a damp cloth for spot cleaning.
Yes, the combination of a ratchet height-adjustable backrest and seat slide function makes it highly adaptable for taller individuals.
Ensure the gas lift is fully seated in the base and verify that the height adjustment lever is not obstructed by debris.
Locate the pump mechanism and activate it repeatedly to inflate the internal bladder; check for any leaks if pressure does not hold.
Tighten the bolts connecting the backrest to the seat mechanism using the provided hex key.
To assemble the chair, ensure you have a clear workspace and follow the included instructions to attach the base, gas lift, and mechanism to the seat pan. Compatibility is generally universal for standard office flooring, though hard floor casters or a chair mat are recommended for smooth movement.
For ongoing care, wipe the upholstery with a soft, damp cloth to manage dust. Check that all bolts and tension screws are tightened every six months to prevent wobbling, and ensure the gas lift is kept free of debris to maintain smooth height adjustment.
