Buy SIHOO Doro S100 Parts From a Local Authorized Dealer or Repairman Near You

If you want guaranteed OEM parts and don’t feel like wrenching on the chair yourself, the safest move is to go through Sihoo’s official channels. Start by checking the Sihoo dealer locator to see if there’s an authorized retailer or service partner near you, then ask them about Doro S100–specific components, pricing, and lead times. If you do not see a nearby option, you can still reach out to Sihoo support directly for parts advice and warranty questions using the contact details linked from their locator page at this official dealer locator.

Tips for Ordering SIHOO Doro S100 Replacement Parts

  • Double-check that your chair is actually the SIHOO Doro S100 (not another Doro or V-series model) using the label under the seat.
  • Use the official manual or exploded diagram to match part names, codes, and mounting points before you click buy.
  • Measure key hardware like caster stem diameter, gas lift size, and base bore to avoid compatibility surprises.
  • Look for listings or dealers that explicitly mention “SIHOO” or “Doro S100” instead of only saying “universal office chair part.”
  • Keep all mounting screws and brackets from the original part; sometimes new parts ship without extra hardware.
  • If you are unsure between two similar parts, email Sihoo support with photos so they can confirm the correct option.

Tools Needed to Repair SIHOO Doro S100

  • Hex/Allen key set: Most S100 bolts use metric hex heads, so a basic Allen key set is your primary tool for loosening and tightening structural screws when swapping parts.
  • Phillips screwdriver: Handy for smaller screws on plastic covers, headrest brackets, and accessory components that must be removed to reach hidden fasteners.
  • Rubber mallet: Lets you gently knock the gas lift or casters out of the base without denting metal or cracking plastic hubs.
  • Needle-nose pliers: Useful for pulling stubborn caster stems, holding nuts in tight spaces, or removing small clips and cable ties around the mechanism.
  • Silicone spray lubricant: After reinstalling parts, a light spray on moving joints reduces squeaks and keeps the tilt and recline mechanisms moving smoothly.

SIHOO Doro S100 Diagram & Manual

For accurate part names, torque guidance, and assembly order, always rely on Sihoo’s official documentation. The company maintains setup videos and downloadable manuals on its setup-guide hub, including materials specific to the Doro series. Head to Sihoo’s official setup guide page and look for the Doro S100 instructions and diagrams. Using the latest official manual makes it much easier to identify parts and reinstall them correctly.

How to Prevent Damage to SIHOO Doro S100 Parts

  • Avoid rocking aggressively or dropping your full weight into the recline, which can stress the tilt and lumbar components.
  • Keep the chair within its recommended weight limit so the gas lift, base, and casters don’t wear out prematurely.
  • Roll the chair on clean, relatively smooth flooring or a quality chair mat instead of rough concrete or damaged tile.
  • Clean hair and lint from the casters regularly so debris does not jam the wheels or score hard floors.
  • Check and retighten armrest and backrest bolts a few times a year to prevent wobble from turning into cracked brackets.
  • Follow Sihoo’s cleaning guidance for mesh and plastic so harsh chemicals do not weaken frames or fade finishes.

Conclusion
Keeping a SIHOO Doro S100 in good shape is mostly about ordering the right parts and taking your time with repairs. With solid diagrams, a few basic tools, and quality replacements, you can keep this chair feeling premium and comfortable for a long, long time.
