Key Features:
- 6D Coordinated Armrests: Pioneering armrests that adapt to any posture, providing support in six directions to alleviate arm and shoulder burden.
- Coordinated Support System: Utilizes a four-axis linkage to evenly distribute pressure from hips and back onto the seat during reclining, promoting healthy spinal support.
- Precise Elastic Adjustment System: Features aerospace-grade material elastic plates with a tension adjustment handle for customized smoothness, offering a zero-gravity experience.
- Bionic Dynamic Lumbar Support System: Replicates the human body's lumbar curve with an innovative dynamic adaptive mechanism, supporting 6D automatic deformation for all-encompassing lumbar support.
- Shock-Absorbing Suspension System: Provides a sensation akin to sitting on soft ground, automatically balancing flexible sitting posture support based on body movement.
2. Setup and Assembly
The SIHOO Doro S300 chair requires assembly upon arrival. Please ensure all components are present before beginning. Refer to the detailed assembly instructions included within your product packaging for step-by-step guidance. All necessary tools are typically provided.

It is recommended to assemble the chair on a soft, clean surface to prevent scratches. While assembly is designed to be straightforward, having a second person assist with heavier components like the seat and backrest can be beneficial.
3. Operating and Adjustments
The SIHOO Doro S300 offers extensive adjustability to customize your seating experience for optimal comfort and ergonomic support. Familiarize yourself with the various controls to fine-tune the chair to your body and preferences.
3.1. Seat Height Adjustment
- Locate the lever on the right side, typically beneath the seat.
- To raise the seat, lift the lever while taking your weight off the seat.
- To lower the seat, lift the lever while remaining seated. Adjust until your feet are flat on the floor and your knees are at a 90-degree angle.
3.2. Seat Depth Adjustment
- Find the lever on the left side, beneath the seat.
- Pull the lever to unlock the seat, then slide the seat forward or backward to achieve the desired depth. Ensure there is a small gap (about two fingers' width) between the edge of the seat and the back of your knees.
- Release the lever to lock the seat in position.
3.3. Recline and Tilt Tension
- The main knob in the middle, beneath the seat, controls the recline lock and tension.
- To lock the chair in an upright position, turn the knob to the appropriate setting.
- To allow for full recline, adjust the knob to the unlocked position.
- To adjust the tension of the recline movement (how much force is needed to recline), turn the knob below the main recline knob. Turn clockwise for more tension, counter-clockwise for less.

3.4. Lumbar Support Adjustment
The Bionic Dynamic Lumbar Support System features dual dynamic lumbar pads that automatically adapt to your body. Additionally, the top part of the backrest can be slid up and down independently to fine-tune the lumbar support position to your specific needs.

3.5. 6D Coordinated Armrests
The groundbreaking 6D armrests offer unparalleled adjustability. They can be moved in virtually any direction (up/down, forward/backward, pivot in/out, and angle rotation) to provide optimal support for your arms and shoulders in any sitting or reclining position. Explore the full range of motion to find your most comfortable setup.
4. Maintenance
Regular maintenance will help prolong the life and performance of your SIHOO Doro S300 chair.
- Cleaning Mesh Fabric: For general cleaning, use a soft brush or vacuum cleaner to remove dust and debris. For spills, gently blot with a clean cloth dampened with mild soap and water. Avoid harsh chemicals or abrasive cleaners.
- Cleaning Frame and Base: Wipe down the metal and plastic components with a soft, damp cloth. Dry immediately to prevent water spots.
- Caster Care: Periodically check the casters (wheels) for tangled hair or debris. Clean them as needed to ensure smooth rolling.
- Check Connections: Every few months, inspect all screws and bolts to ensure they are tight. Re-tighten if necessary to maintain stability and prevent squeaks.

If you encounter any issues with your SIHOO Doro S300 chair, refer to the common solutions below. If the problem persists, please contact customer support.
5.1. Chair Squeaks or Wobbles
