How to Use a SIHOO M18 Series Chair Properly
How do I adjust the SIHOO M18 for the best ergonomic support?
To get the most ergonomic benefit from your SIHOO M18:
- Adjust so your feet are flat on the floor and your knees are at a 90° angle.
- Align the built-in lumbar support with the curve of your lower back to reduce pressure.
- Position the 3D armrests so your elbows rest naturally at desk level, preventing shoulder strain.
What’s the best way to use the recline and tilt features?
The SIHOO M18 offers a smooth reclining mechanism with tilt tension control:
- Use the tilt lock to set your preferred recline angle (ideal for reading or relaxing).
- Adjust the tilt tension knob underneath the seat to control how easily the chair leans back—loosen for a relaxed recline, tighten for firm support.
- Reclining for a few minutes during breaks can help relieve pressure on your spine and keep you energised.
Can I sit for long hours in the M18?
Yes, the SIHOO M18 is built for extended use—but proper setup and posture are key:
- Sit with your back fully supported by the mesh backrest and lumbar support.
- Avoid slouching or leaning forward for long periods—rely on the chair’s ergonomic design to support your posture.
- Take short standing breaks every 60–90 minutes to improve circulation and reduce fatigue.
