SIHOO support FAQ

Common questions about manuals, registration, and support for this brand.

  • How do I fix a shaking armrest on my SIHOO chair?

    First, ensure that the screws connecting the armrest are tightened sufficiently. If the issue persists, check the stability of the armrest pad itself.

  • The backrest mesh is broken; what should I do?

    Please contact SIHOO customer support with your order details to arrange for a replacement backrest.

  • What should I do if the chair is too short for me?

    Adjust the chair to its maximum height using the lever. If it is still not suitable, the gas lift may need to be replaced. Contact support for assistance.

  • I hear noises when sitting on the chair.

    Check if all parts and screws are installed tightly. If the noise continues, there might be an issue with the mechanism. Recording a video of the issue can help support diagnose it.

  • There is an abnormal odor when I unpack the chair.

    It is recommended to leave the chair in a well-ventilated room for 2-3 days before use to allow any new-material odors to dissipate.

  • What if I receive a damaged or incorrect product?

    Contact SIHOO support immediately with your order number and photos of the product and packaging. Keep all packaging materials until the claim is resolved.
