AI Summary
- "Open box", "refurbished" and private second-hand have different meanings unless the seller defines them in writing.
- Count missing parts, mesh wear, return freight and warranty limitations alongside the advertised discount. Source 2
- Do not describe a unit as manufacturer-refurbished without the manufacturer’s documentation.
Decision table
| Situation | Practical choice |
|---|---|
| Seller supplies serial number, repair record and returns | Compare its complete cost with the same-version new chair. |
| Only vague condition language is offered | Request detailed photographs and records or walk away. |
What to do
Request photographs of the seat mesh, mechanism, cylinder, castors, serial number and packaging. Ask who refurbished it, what was replaced, and whether the purchase has a written warranty. Sihoo’s after-sales terms mention that an eligible quality claim may be satisfied with an equivalent factory-refurbished replacement. That does not establish the status or warranty of every open-box listing on the market. Source 1 Source 2
Compare the whole cost of the actual unit
| Evidence | Open-box or refurbished seller | Same-version new chair |
|---|---|---|
| Condition | Photos, use history and repair record | New-product listing |
| Package contents | Every fitting and missing part | Full included-parts list |
| Cover | Written unit-specific warranty | Current new-order terms |
| Delivered cost | Price, freight and required replacements | Price and freight |
| Return risk | Address, collection and deductions | Equivalent return questions |
Example inputs only: an open-box chair at £150 plus £20 delivery and £35 for missing parts totals £205. If a complete new version delivered costs £220, the difference is £15, not the £70 implied by comparing headline prices. Do not count a missing-part repair as feasible until the correct component is available and authorised.
The Sihoo after-sales page mentions equivalent factory-refurbished replacements in a claim process. That wording does not authenticate a third-party retail unit. Ask who inspected the chair, what was replaced and which serial number the paperwork covers. Walk away if an essential load-bearing fault is unresolved or the seller will not identify the unit and its return route.
Frequently asked questions
Is open-box the same as new?
No. Verify use history and condition.
Does every factory-refurbished chair carry three years?
Do not assume; get the terms for that individual unit.
Can I claim warranty without a receipt?
Sihoo asks for valid proof of purchase. Source 2
How much discount makes it worthwhile?
There is no universal percentage; compare total cost and documented risks.
