The Onyx Ergo Posture Chair is designed for office professionals and remote workers who require high-level ergonomic support during extended periods of sitting. Its primary benefit is the combination of a contoured foam structure and a highly adjustable asynchronous mechanism that enables users to achieve a precise, custom fit for their body type. While it offers premium adjustability, users should be aware that the multiple-lever configuration requires some initial trial and error to find the optimal ergonomic settings.

Regularly check the castors for hair or debris buildup to ensure smooth movement across office flooring, and periodically inspect the lever functions to ensure they move freely.
