The SIHOO Doro C300 is designed for professionals and home-office users seeking superior ergonomic support during extended work hours. Its primary benefit is a self-adaptive lumbar system and intelligent weight-sensitive recline that eliminates the need for manual tension adjustments, providing consistent spinal alignment throughout the day. While it offers premium comfort features like 3D armrests and breathable mesh, the caveat is its specific assembly requirements which demand attention to detail to ensure all mechanical components function optimally.

The chair is certified to support users up to 150kg.
No, the Doro C300 uses an intelligent weight-sensitive mechanism that automatically adjusts recline tension based on the user's weight.
It meets international safety and performance standards including EN1335, TÜV, and BIFMA.
The chair allows for locking at three specific tilt angles: 110°, 120°, and 130°.
The lumbar support is self-adaptive, meaning it moves dynamically with your body rather than requiring fixed manual height settings.
Check all bolts and screws to ensure they are fully tightened; apply a small amount of silicone-based lubricant to the recline mechanism if necessary.
Ensure you are sitting fully back in the chair so the weight-sensitive mechanism can properly engage with your posture.
Verify the mounting bolts underneath the seat pan are secure and check that the 3D movement locking mechanisms are fully engaged.
Assembly of the Doro C300 should be performed on a soft surface like a rug to avoid scratching the finish. Ensure all screws are tightened in a cross-pattern to maintain frame alignment. For care, use a vacuum with a soft brush attachment to clear dust from the mesh backrest weekly. If the frame experiences light soiling, wipe down with a microfiber cloth dampened with mild soapy water. Avoid using harsh chemical cleaners, as these can degrade the integrity of the mesh fibers or the surface finish of the frame components. Ensure the gas lift remains lubricated if you notice any squeaking over prolonged periods of use.
