Operating Instructions
Adjusting the Backrest
The backrest of the SIHOO L3D chair can be adjusted to three different height levels, providing up to 1.5 inches (approximately 4 cm) of vertical adjustment. To adjust, simply lift the backrest upwards. It will click into place at each level. To lower, lift it past the highest setting, and it will reset to the lowest position.
Adjusting the Seat Depth
Customize your seating experience with the adjustable seat depth, allowing for a maximum adjustment of 1.97 inches (approximately 5 cm). This feature helps you find the perfect fit for your hips and thighs, enhancing comfort and ergonomic support.
Adjusting the Seat Height
The seat height can be adjusted to suit various desk heights and user preferences. The seat height ranges from approximately 16.75 inches (42.5 cm) to 19.75 inches (50 cm) at the center front. Use the lever located under the seat to raise or lower the chair. To raise, lift the lever while taking your weight off the seat. To lower, lift the lever while seated.
Recline Function
The chair features a recline function where the backrest can tilt backward. Please note that the recline position is not lockable and will return to an upright position when pressure is released. The recline mechanism offers minimal tension or resistance.
Mobility
The chair is equipped with a five-wheel base for easy movement. The casters are designed to roll smoothly on various floor surfaces, including hardwood floors. Avoid lifting the chair by the seat or arms without supporting the base, as the wheeled base may separate.

Maintenance and Care
- Cleaning Faux Leather: The premium faux leather surface is designed to be easy to clean and resists stains, scratches, and peeling. For general cleaning, wipe with a soft, damp cloth. For tougher stains, use a mild soap solution and wipe dry immediately. Avoid harsh chemicals or abrasive cleaners.
- Frame Care: Wipe the metal frame with a soft, dry cloth to remove dust.
- Caster Maintenance: Periodically check the casters for hair or debris that may hinder smooth movement. Clean as needed.
- Hardware Check: Regularly inspect all screws and bolts to ensure they remain tight. Re-tighten any loose hardware to maintain stability and safety.
- Avoid Direct Sunlight: Prolonged exposure to direct sunlight can cause the faux leather to fade or crack. Position the chair away from direct sunlight when possible.
