Always ensure all components are securely fastened before use. Do not stand on the chair. Do not use the chair if any parts are damaged or missing.
2. Setup and Assembly
Minimal assembly is required for your Yaheetech Armless Desk Chair. Typically, this involves attaching the casters to the base and securing the seat and backrest components.
2.1 Unpacking and Component Check
Carefully unpack all components from the box. Verify that all parts listed in the packaging contents are present and undamaged.
2.2 Important Pre-Assembly Step: Remove Plastic Cap
Before assembling, locate the pneumatic cylinder (gas lift). There is a black plastic cap on the top of the cylinder that must be removed prior to installation. Failure to remove this cap will prevent the chair's height adjustment mechanism from functioning correctly.
