You want to work with trustworthy factories, but the fear of scams, delays, and poor quality holds you back.
To find reliable mattress manufacturers in China, verify licenses and ISO/CertiPUR-US certifications, conduct video audits, check factory ownership, and validate production capacity through Qichacha or third-party auditors.
I’ve worked with many importers who came to me after having issues with fake suppliers or delayed orders. I’m going to walk you through exactly how I help clients verify and audit mattress factories in China—so you avoid mistakes and protect your brand.
How to verify a factory in China?
Many suppliers claim to be factories, but are just trading companies without real production capabilities.
To verify a Chinese factory, check their business license scope via Qichacha, confirm factory certifications like ISO 9001, and request a live video tour showing machines, staff, and raw materials.
Start with the business license. The supplier should provide a Chinese license. Cross-check the registration number on Qichacha1. Make sure the scope includes manufacturing, not just sales.
Next, validate their certifications. ISO 9001 proves quality systems, CertiPUR-US for foam safety, and OEKO-TEX for fabric safety. These should have valid dates and certification bodies listed.
Ask for a live video tour. Request to see the foam cutting line, sewing area, compression packing process, and finished goods warehouse. Many real factories are happy to show their processes.
If the factory refuses a video tour or delays document sharing, treat that as a red flag.
How to audit a factory?
Seeing a clean showroom is not enough. You need a structured way to check production quality and working conditions.
You audit a factory by using a detailed checklist or hiring third-party agencies like SGS or TÜV to evaluate capacity, safety, materials, labor, and quality systems.
An audit can be done on-site or remotely. For on-site audits, third-party companies like TÜV, SGS, or Intertek send certified inspectors. They evaluate:
| Audit Component | What’s Checked |
|---|---|
| Capacity & Equipment | Machine types, staff, daily/weekly output |
| Safety & Labor | Fire exits, PPE, insurance, contracts |
| Material Records | Foam and spring specs, purchase invoices |
| QC Process | Incoming/outgoing checks, defect logs |
| Compliance | ISO, CertiPUR-US, social audits (BSCI) |
A well-executed audit reveals operational health, not just cosmetic impressions.
What does audited mean on Made in China?
You often see “audited supplier” badges on sourcing sites. But what does it really prove?
“Audited” means the factory has undergone a structured inspection by a third-party firm, confirming business legitimacy, production, quality control, and legal compliance.
On Made-in-China.com, “Audited Supplier” indicates an agency like SGS or TÜV has physically visited the factory.
These agencies check:
- Legal registration and license validity
- Facility ownership (not just rented space)
- Photos and videos of real equipment
- Quality system documents
- Employee count and wage slips
- Product samples and material records
An audited factory is not always perfect—but it shows they’re open to being checked.
How to search factories in China?
The internet shows thousands of options. But how do you find real ones, not just agents?
Search mattress factories on platforms like Alibaba (with "verified manufacturer" filter), Made-in-China, or Global Sources, and cross-check with legal platforms like Qichacha.
"Search Mattress Factories in China")
Start with Alibaba and apply the “Verified Manufacturer” and “Onsite Checked” filters. Don’t rely on response rate or transaction level alone.
Visit Made-in-China and check factory audit reports under each profile.
Search the factory name in Chinese on Qichacha. This reveals ownership, registered capital, business scope, and license expiry.
If you're attending trade shows2 like Canton Fair or CIFF, scan their exhibitor list in the bedding category. These brands often have actual production capacity3.
How do I find reliable mattress manufacturers in China?
You may find dozens of suppliers online—but who’s real, and who’s just a middleman?
To find reliable mattress manufacturers, validate their license, check ownership via Qichacha, request certifications like ISO and CertiPUR-US, and audit their workshop either in person or via video.
Reliable factories don’t hide details. They openly share documents, past client references, and welcome third-party inspections.
Start by confirming their legal status. Ask for a Chinese business license and use Qichacha to check ownership, business scope, and age.
Next, request ISO 9001 for quality systems and CertiPUR-US for foam safety. These are essential for exporting to the US, EU, or Australia.
Then, assess if they own or rent their facility. A real factory has full control over production—traders don’t.
Finally, verify operational capacity: daily output, staff numbers, machines, and warehouse space. If they claim to ship 40HQs weekly, their team and space should reflect that.
If all checks are clear, schedule a trial order and monitor communication quality, sample consistency, and delivery reliability.
| Verification Area | Method |
|---|---|
| Legal Check | Qichacha, license in Chinese |
| Certification | ISO, CertiPUR-US, OEKO-TEX |
| Factory Ownership | Ask for lease or title proof |
| Output & Equipment | Live video tour, photos |
| Previous Clients | Request 2–3 contact references |
What should be included in a factory audit checklist?
Without a structured checklist, you might miss key issues like expired materials or fire safety risks.
A mattress factory audit checklist should include business license, production output, quality systems, labor conditions, material sourcing, and warehouse practices.
A complete audit checklist4 has the following key items:
| Checklist Section | What to Inspect |
|---|---|
| Legal Status | Business license, export permit |
| Production | Machines, monthly capacity, factory layout |
| Materials | Foam specs, fire-retardant labels, COAs |
| QC Process | Incoming checks, mid-line inspection, testing |
| Labor & Safety | Fire exits, insurance, contracts, PPE |
| Warehouse | Humidity control, compression storage |
| Documentation | ISO, CertiPUR-US, maintenance records |
This checklist ensures nothing critical gets overlooked.
How do I ensure mattress quality from a Chinese supplier?
Mattress quality is hard to judge just by pictures. You need objective methods to verify.
Ensure quality by asking for SGS or TÜV test reports5, checking foam density, doing recovery tests, and requiring flame-retardant and VOC certifications.
Start with lab tests. Check foam density6—28D or higher for comfort layers, 35D+ for support foam.
Confirm the supplier holds CertiPUR-US and OEKO-TEX for materials. If shipping to the US or EU, ask for CFR 1633 or BS 7177 fire-resistance test reports.
Ask for compression and recovery tests. If a mattress is vacuum-packed for too long, foam may not bounce back.
Finally, inspect finished goods for stitching quality, edge alignment, and label accuracy. Always confirm that bulk production matches the approved sample.
What are common challenges in auditing7 Chinese factories?
Audits are valuable—but they’re not perfect. Some problems still go unnoticed.
Challenges include staged production setups, language barriers, document manipulation, and difficulty observing real daily operations during short visits.
Many factories "stage" their best floor for audits—showing only trained staff, unused machines, and perfect products.
Language gaps also lead to misunderstandings. Audit staff may be bilingual, but workers may not understand instructions, affecting observations.
Some factories provide edited documents or show expired certificates that look valid. You must check the source, issue date, and validity.
To minimize risk:
- Conduct unannounced re-visits
- Use third-party video inspections
- Ask for raw photo sets with metadata
What is the cost of auditing8 a mattress factory in China?
Audits are not free. But how much should you really pay?
Factory audits typically cost $150–$398 per day depending on the depth, location, and whether the audit is remote or in-person.
Here’s a simple breakdown:
| Audit Type | Provider | Typical Cost | Scope |
|---|---|---|---|
| Remote Audit | Freelancers, small QA firms | $150–$250 | Video walk-through + docs |
| In-Person Audit | TÜV, SGS, Intertek | $298–$398 | Full-day visit + formal report |
If you're auditing 2–3 factories at once, some agencies offer volume discounts.
Audits are a small investment compared to a failed 40HQ shipment.
How to assess if a mattress factory follows industry standards?
You want more than a factory that “looks good.” You want one that meets global safety and performance rules.
Check if the factory holds valid certifications (ISO, CertiPUR-US), passes emission and fire safety tests, and has documented QC systems that align with EU/US standards.
Request their ISO 9001 and 14001 certificates. These show process control and environmental management.
Check if foam carries CertiPUR-US, ensuring low VOC emissions and safe chemicals. For exports to Europe, confirm REACH compliance.
Ask for fire-resistance reports like CFR 1633 (US) or BS 7177 (UK). These should be lab-certified.
Confirm their in-house QC logs—do they conduct inspections at each stage? Are test results filed and archived?
This shows if they truly follow standards, not just claim to.
