FAQ

The YZ-B11 chair mechanism is a robust and versatile component designed to fit a wide range of modern office chairs that utilize gas lift systems. Made from high-quality, heavy-duty metal, this mechanism ensures long-term durability and smooth operation. It is engineered to support both seat height adjustment and tilt functionality, making it ideal for ergonomic seating applications in commercial or home office settings.

This mechanism includes two independent control handles:

Handle A is responsible for adjusting the seat height, allowing users to lift or lower the chair according to their comfort and desk height.
Handle B controls the tilt lock function, enabling users to secure the backrest in a fixed position or release it for free tilting.
The unit supports weight capacities typically required for B-Class chairs, and is compatible with standard gas cylinders and chair bases. Its installation is simple, making it suitable for chair manufacturers, repair technicians, or DIY replacements. The smooth surface treatment and anti-corrosion coating improve its performance in high-use environments.

Whether you are building new chairs or replacing old mechanisms, the YZ-B11 offers reliability, comfort, and flexibility. It is widely used in executive chairs, task chairs, and swivel office chairs.
