CFR 1633, BS 7177, and EN 597 explained for mattress buyers — how natural-fibre builds meet compliance without chemical flame retardants. Download the free standard comparison guide.

Mattress fire-safety standards are the legally mandated tests a finished mattress must pass before it can be sold in a given market. For luxury mattresses, the three most frequently cited are: 16 CFR Part 1633 — the U.S. federal open-flame standard that requires a mattress to withstand a 30-minute open-flame exposure without exceeding heat-release limits; BS 7177 — the UK standard that grades resistance by ignition-source hazard level (Source 0–5); and EN 597-1 / EN 597-2 — the EU pair covering cigarette-smoulder (597-1) and match-flame (597-2) resistance. Each is a mandatory, market-specific regulation, not a voluntary certification.

Key Takeaway

Every market you sell into has its own mattress fire-safety rule, and none of them are optional. The United States uses 16 CFR Part 1633 (open-flame, 30-minute test). The United Kingdom uses BS 7177 with ignition-source hazard levels. The European Union uses EN 597-1 and EN 597-2. The trap for luxury buyers is assuming compliance requires chemical flame retardants. It does not. A dense natural-fibre build (wool over horsehair, properly tufted) can pass on material behaviour alone. The factory must still hold current, verifiable test reports from a named lab for the exact model you are buying.

Market Standard Core Test What It Proves
United States 16 CFR Part 1633 Open-flame, 30-min Mattress resists ignition and limits heat release
United Kingdom BS 7177 Cigarette + flame, by Source level Hazard class from Source 0 (low) to Source 5 (very high)
European Union EN 597-1 / EN 597-2 Cigarette (597-1) + match-flame equivalent (597-2) Smoulder and flame resistance of the mattress

If you ship to more than one region, the factory needs a report for each. A US report does not cover the UK or EU.

CFR 1633 (United States)

16 CFR Part 1633 is the federal open-flame standard. A full mattress-plus-foundation assembly is exposed to a specified flame for 30 minutes, and the test measures heat release and char area.

Data Point: CFR 1633 Test Parameters

Parameter Requirement Notes
Test assembly Mattress + foundation (where applicable) Must be the actual product sold
Flame source Open flame, specified intensity Not a smoulder test
Duration 30 minutes Full test duration
Heat release rate Must stay under limit for full 30 minutes Primary pass/fail criterion
Char area Must not exceed limits at 12-minute mark Secondary criterion
Report must name Exact model, cover, filling build Generic "series" coverage is insufficient
Source: bonjourluxe Content Team, based on China's mattress belt analysis, 2025–2026
  • Applies to mattresses sold in the US (including imports)
  • Tested as a complete set where possible, or with a specified foundation
  • Pass = heat-release rate stays under the limit for the full 30 minutes
  • Report must name the model, the cover, and the filling build

A mattress that passes CFR 1633 on wool-and-horsehair construction is passing on fibre behaviour, not on a chemical soak.

For your CFR 1633 certificate China mattress requirement, always request a model-specific report and verify the report number on the issuing lab's website. Do not accept a generic family-coverage letter.

BS 7177 (United Kingdom)

BS 7177 grades mattresses by ignition-source severity, from Source 0 (cigarette only, low hazard) up to Source 5 (high hazard, e.g. care homes). Most retail and hospitality requires at least Source 5 for contract use.

Data Point: BS 7177 Source Levels and Application

Source Level Ignition Source Application Typical Buyer Requirement
Source 0 Cigarette only Domestic low-hazard Domestic retail (minimum)
Source 1 Cigarette + match Low domestic Not sufficient for hospitality
Source 2 Cigarette + lighter flame Medium domestic Some contract use
Source 3 Elevated flame source Higher risk domestic Growing requirement
Source 4 High-intensity flame High-risk domestic/contract Many retailers require
Source 5 Severe hazard Care homes, hotels, high-risk Most UK retail and hospitality
Source: bonjourluxe Content Team, based on China's mattress belt analysis, 2025–2026
  • Source 0–1: cigarette and match (domestic low hazard)
  • Source 5: highest, for high-risk environments
  • Report states the Source level achieved, not just "passed BS 7177"
  • Higher Source level usually means more resilient fibre layering near the surface

Ask for the Source level explicitly. "BS 7177 compliant" without a level is incomplete. A BS 7177 Source 5 mattress report must explicitly state "Source 5 achieved" — not just a pass notation.

EN 597 (European Union)

The EU uses two coupled tests: EN 597-1 (cigarette smoulder) and EN 597-2 (match-flame equivalent). Together they cover the smoulder and flame resistance of the mattress surface and filling.

  • EN 597-1: lit cigarette left on the surface, no progressive smouldering
  • EN 597-2: controlled gas flame applied, no sustained ignition
  • Applies across EU member states for mattresses placed on the market
  • Wool-rich surfaces perform well because wool is inherently flame-resistant

Chemical FR Treatments vs Natural Compliance

The legacy route to compliance is dousing foam and fabric in chemical flame retardants. That solves the test and creates two problems: VOC off-gassing and a health/restriction headache under EU REACH and US state rules.

  • Chemical FR: cheap, effective on the test, poor for indoor air
  • Natural compliance: wool and horsehair resist ignition on their own
  • A dense, tufted natural build can meet CFR 1633 / BS 7177 / EN 597 with no added FR chemicals

You should not have to choose between passing fire safety and keeping chemicals out of the bed. A correctly built natural-fibre mattress does both. Tufted vs Glued Construction

How Natural Fibres Pass

Wool is the key. It is naturally flame-resistant. It chars rather than melts, and it self-extinguishes. Layered over horsehair and compressed by hand-tufting, the surface resists both smoulder (cigarette) and flame (match/open-flame) without additive treatments.

Data Point: Natural Fibre Fire Resistance Mechanism

Fibre Flame Behaviour Self-Extinguishing FR Mechanism
Wool Chars, does not melt Yes Natural lanolin; low heat release
Horsehair Resilient; high ignition point Yes Mineral content; structural integrity
Cotton Burns readily No Requires treatment or layering
Foam (polyurethane) Melts, drips, burns No Always requires chemical FR treatment
Polyester Melts, burns No Always requires chemical FR treatment
Source: bonjourluxe Content Team, based on China's mattress belt analysis, 2025–2026
  • Wool: chars, does not melt, self-extinguishes
  • Horsehair: resilient, holds loft, supports the wool layer
  • Tufting: compresses the build so air gaps (where flame travels) are minimised
  • Result: compliance from construction, not from a chemical bath

Test Report Verification

A report you cannot verify is not a report. Before you rely on any fire-safety claim:

  • Confirm the report names a recognised lab (SGS, Intertek, Bureau Veritas, TUV)
  • Verify the report number on the lab's own website
  • Check the model name matches the SKU you are buying, not a "series"
  • Confirm the date is current. Standards and builds change.
  • Request per-model reports, not a single family-coverage letter

Ask for the model-specific fire-safety report and verify the number on the lab's site. If the factory can only show a cover-letter for the whole range, you do not yet have proof. Verify Factory

Bonjour Luxe Fire-Safety Standard

: Bonjour Luxe achieves CFR 1633, BS 7177 Source 5, and EN 597 compliance on its natural-fibre builds with no chemical flame-retardant treatments, and provides model-specific SGS/Intertek test reports before every shipment.


Five Steps to Verify a Fire-Safety Test Report

  1. Identify the target market first —— The US requires CFR 1633, the UK BS 7177 (graded by premises type), the EU EN 597. A report against the wrong standard is worthless.
  2. Check the report number and lab accreditation —— The report must come from an ISO/IEC 17025 accredited lab, and the number must be searchable on the lab's or the scheme's site.
  3. Match the tested sample description —— The layer order, grammage and thickness in the report must match what actually ships. Testing a simplified sample invalidates the report.
  4. Check the issue date and validity —— Fire-safety reports typically run 1–3 years, and must be re-issued after any change of material or supplier.
  5. Confirm the compliance route —— Ask whether the bed passes on natural fibres alone or relies on flame-retardant chemicals. The latter requires an additional chemical safety declaration.

Frequently Asked Questions

Q: Do I need different fire-safety reports for the US, UK, and EU? Yes. CFR 1633, BS 7177, and EN 597 are separate standards with separate tests. A report for one market does not cover the others. Hold a current, model-specific report for every market you ship to.

Q: Can a natural-fibre mattress really pass without chemical retardants? Yes, if the build is right. Wool-rich, tufted construction resists ignition on its own. Many heritage European luxury mattresses have always passed this way. The factory must still prove it with a named-lab report for your exact model.

Q: What BS 7177 Source level should I require? For retail and most hospitality, Source 5 is the practical target. Source 0–1 is domestic low-hazard only. Specify the level in your purchase order, not just "BS 7177 compliant."

Q: How do I verify a fire-safety report is genuine? Look up the report number on the issuing lab's website (SGS, Intertek, Bureau Veritas, TUV). The model name must match your SKU and the date must be current. A family-coverage letter is not proof for a specific product.

Q: Does avoiding chemical FR treatments help with other compliance? It helps directly with EU REACH and US indoor-air rules (California 01350), because you are removing a major chemical and VOC source at the source. It also simplifies your materials disclosure to downstream retailers.

Frequently Asked Questions

What are the mattress flammability standards for the US, UK and EU?
The US uses 16 CFR Part 1633 (open flame, 30-minute test). The UK uses BS 7177, graded by ignition-source hazard level Source 0–5. The EU uses EN 597-1 (smouldering cigarette) plus EN 597-2 (match flame). Australia adds AS/NZS 2220, similar to EN 597. All are mandatory market-specific regulations, not voluntary certifications.
Are these flammability standards optional?
No. Each is a legally required test before sale in that market, and none can be waived. The common mistake is assuming one report covers everything — a US report does not cover the UK or the EU. If you ship to several regions, the factory needs a separate report for each market.
How does the CFR 1633 test actually work, and what is the pass criterion?
The complete mattress with its foundation is exposed to an open flame of specified intensity for 30 minutes while heat release and char area are measured. To pass, the heat release rate must stay below the limit across the full 30 minutes (the primary criterion), and the char area at 12 minutes must not exceed the limit (the secondary criterion). It applies to all mattresses sold in the US, imports included.
What must a CFR 1633 report state?
It must name the exact model, the ticking and the filling construction. A generic "series" coverage letter is not acceptable, because changing the filling construction directly changes burn behaviour. Demand a model-specific report and verify the report number on the issuing lab's website rather than accepting a scan.
What do BS 7177 Source 0–5 levels mean?
They are flammability grades set by ignition-source hazard, from Source 0 (low hazard) to Source 5 (very high hazard); the higher the level, the stricter the test. Which level you need depends on the setting — residential, hotel, hospital and marine each carry different requirements. Confirm your premises type first, then ask the factory for a report at that level.
What do EN 597-1 and EN 597-2 each test?
EN 597-1 tests resistance to a smouldering cigarette; EN 597-2 tests resistance to a match-flame equivalent. The pass criteria are no sustained smouldering and no sustained flaming respectively. Together they cover smoulder and flame resistance across the mattress surface and fillings, and entering the EU requires passing both.
Can natural-fibre mattresses pass without chemical flame retardants?
Yes. This is the most common misconception among luxury buyers — assuming compliance requires chemical retardants. In practice a dense natural-fibre build (wool over horsehair, properly tufted) can pass on material performance alone. Wool has a high ignition point and self-extinguishes, so it acts as a natural fire barrier.
How do I tell whether a bed passes on materials or on chemical soaking?
Ask the factory directly whether a chemical flame retardant is added. If it is, require an additional chemical safety declaration and check whether any restricted substance is involved (EU REACH maintains a clear control list). If they claim a materials-only pass, verify that the filling construction described in the test report matches what you are actually ordering.
How long is a flammability report valid, and when must you retest?
Validity is typically 1–3 years depending on the certification body. More importantly, any change of material, supplier or filling structure requires fresh testing even if the report is still in date. Covering a new construction with an old report is the most common compliance gap.
How do I verify a flammability report is genuine?
Three steps: confirm the issuing lab holds ISO/IEC 17025 accreditation; enter the report number on the lab's or the scheme's official site; and check that the model, ticking and filling construction in the report match what will actually ship. A simplified test sample, or a report that does not match the shipped build, is invalid.
Why does the sample description on the report matter so much?
Because burn behaviour depends heavily on the specific material combination. The same silhouette can go from pass to fail by changing one filling layer. When reviewing, compare the layer order, grammage and thickness in the report line by line against your purchase specification. Any mismatch makes the report invalid and puts both clearance and shelf placement at risk.
How should flammability responsibility be written into the contract?
State three things: the specific standard for your target market (for example 16 CFR Part 1633 or BS 7177 Source X); require a model-specific, in-date report whose number is verifiable on the issuing lab's site; and assign to the factory any loss from customs detention or delisting caused by a compliance failure.
