Operating Instructions
Your Primy Drafting Chair offers several adjustment features to ensure optimal comfort and ergonomic support.
Chair Height Adjustment
To adjust the chair's height, locate the lever under the right side of the seat. While seated, pull the lever up to lower the chair. To raise the chair, stand up slightly to remove weight from the seat, then pull the lever up. Release the lever at your desired height. The chair offers approximately 8 inches of height adjustment.

This illustration demonstrates the lever used to adjust the chair's height, indicating an approximate 8-inch range for vertical movement.
Adjustable Lumbar Support
The chair features an adjustable lumbar support on the backrest. Gently push or pull the lumbar support mechanism to adjust its position vertically (approximately 2 inches or 5 cm) to best fit the curve of your lower back and relieve pressure.

Flip-up Armrests
The armrests can be flipped up by rotating them upwards 90 degrees. This feature allows the chair to be pushed closer to a desk or to save space when not in use.
Adjustable Footrest Ring
The footrest ring can be adjusted along the gas lift cylinder to accommodate different user heights and desk configurations. Loosen the knob on the footrest ring, slide it to your preferred height, and then tighten the knob securely. This helps maintain a comfortable leg position and reduces pressure on the back of your thighs.

360° Swivel and Mobility
The chair features a 360-degree swivel function for easy rotation and smooth-rolling casters for effortless movement across hard floor surfaces. The five-claw base ensures stability during movement and use.

Maintenance
Regular maintenance will help prolong the life and performance of your Primy Drafting Chair.
- Cleaning: For general cleaning, wipe surfaces with a damp cloth. For more thorough cleaning, the manufacturer recommends to "scrub" the chair. Use a mild soap solution if necessary, and dry immediately. Avoid harsh chemicals or abrasive cleaners.
- Mesh Back: The breathable mesh back can be gently wiped down with a damp cloth. For deeper cleaning, a soft brush can be used with a mild detergent solution, then wiped clean.
- Cushion: The seat cushion, filled with high-density foam, can be spot cleaned.
- Casters: Periodically check casters for hair or debris and clean as needed to ensure smooth rolling.
- Hardware: Occasionally check all screws and bolts to ensure they are tight. Retighten if necessary to maintain stability.
Troubleshooting
If you encounter any issues with your Primy Drafting Chair, please refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Chair does not stay at desired height / Sinks down | Gas lift cylinder malfunction or improper installation. | Ensure the gas lift cylinder is correctly seated in the base and seat mechanism. If the issue persists, the gas lift may need replacement. Contact customer service. |
| Squeaking or creaking noises | Loose hardware or friction between components. | Check and tighten all screws and bolts, especially those connecting the seat plate to the seat and backrest. A small amount of silicone lubricant can be applied to moving parts if needed. |
| Casters not rolling smoothly | Debris (hair, lint) caught in casters or damaged casters. | Turn the chair over and carefully remove any debris from the caster wheels. If casters are damaged, they may need to be replaced. |
| Lumbar support not adjusting | Mechanism jammed or broken. | Gently try to move the lumbar support. Do not force it. If it remains stuck, contact customer service. |
