Setup & Assembly

For detailed step-by-step assembly instructions, please refer to the official Installation Manual (PDF) provided with your product. A digital version may be available via the product's Amazon page under the 'Documents' section.

Below is an assembly video provided by the manufacturer to guide you through the process:

Key Assembly Tips:

• Ensure all components are present before starting assembly. Refer to the parts list in the manual.
• When attaching the wheels to the base, ensure the wheel shaft is perfectly straight when inserting into the base. Applying firm, consistent pressure or using a rubber mallet (gently) can help.
• Do not fully tighten screws until all components are loosely assembled, then tighten them securely. This allows for proper alignment.

Operating Instructions

Your Yaheetech office chair is designed with several adjustable features to maximize your comfort and ergonomic support.

Adjusting Seat Height:

Locate the lever on the right side under the seat. To raise the seat, lift the lever while taking your weight off the chair. To lower the seat, lift the lever while remaining seated.

Recline and Tilt Tension:

To recline the chair, pull the lever outwards. The chair will now allow you to lean back. To lock the chair in an upright position, push the lever inwards. The tilt tension knob, located under the seat, can be rotated to adjust the resistance of the recline function. Turn clockwise for more resistance, counter-clockwise for less.

360-Degree Swivel:

The chair is equipped with a 360-degree swivel function, allowing for easy rotation and maneuverability without needing to move the entire chair.
