BS 7177 explained: what a mattress importer actually has to prove
The short answer: to sell a mattress in the UK you must satisfy two separate legal instruments — the fillings must comply with the Furniture and Furnishings (Fire) (Safety) Regulations 1988, and the finished mattress must be safe under the General Product Safety Regulations 2005, which is demonstrated by the complete construction passing the appropriate hazard category of BS 7177:2008+A1:2011. For a hotel, that means the medium hazard category, which adds the Crib 5 wooden-crib test on top of the cigarette and match tests.
That paragraph is the whole regime. Everything below is the detail you need to buy against it without getting caught.
Why this matters more than it looks
Britain regulates mattress flammability harder than any other market, and the reason is historical: bedroom fires started by smokers' materials drove the legislation in the 1980s, and the framework has been tightened rather than relaxed ever since.
The gap between the law and reality is wide. In the Project Phoenix testing programme run by the National Bed Federation and the European Bedding Industries' Association, 101 mattresses on sale in the UK were tested against the fire regulations. Among products imported from outside the UK and EU, 65% failed — with non-compliant fillings and missing labels alongside the failures.
Read that number the right way. Two out of three imported mattresses on the UK market would not survive a serious test. If you are importing, that is your risk. If you are a supplier who genuinely complies, that is your margin.
The two instruments, and why both apply
| Instrument | What it governs |
|---|---|
| Furniture and Furnishings (Fire) (Safety) Regulations 1988 amended 1989, 1993, 2010 and again in October 2025 | The filling materials. This is where the schedules live: polyurethane foam block to Schedule 1 Part I, foam crumb to Schedule 1 Part II, rubber latex foam to Schedule 1 Part III. Non-foam fillings — wool, horsehair, cotton, jute, silk — must also satisfy the ignitability requirements that apply to fillings. |
| General Product Safety Regulations 2005 | The finished product. The mattress must be safe, and the established way to demonstrate that for mattresses and bed bases is a complete construction that passes the relevant BS 7177 hazard rating. |
Note the word complete in the second row. The tests are carried out on a section of mattress that replicates the actual make-up of the unit — including the surface features: tufting, quilt lines and the tape edge. You are not testing a filling in isolation; you are testing what a customer would actually own.
BS 7177: the four hazard categories
BS 7177:2008+A1:2011, "Specification for resistance to ignition of mattresses, mattress pads, divans and bed bases", does not apply one test to everything. It sorts premises by fire risk and demands more ignition sources as the risk rises. The two base tests apply at every level; the crib tests are added on top.
| Hazard category | Ignition sources that must be resisted | Typical premises |
|---|---|---|
| Low hazard | Smouldering cigarette (EN 597-1:1994) and match flame equivalent (EN 597-2:1994) | Domestic dwellings, including non-motorised caravans |
| Medium hazard | The two base tests plus ignition source 5 to BS 6807:2006, Clause 9 — the wooden crib, applied to the top and the edge of the bed | Hotels, guest houses, hostels, halls of residence at universities and colleges, boarding schools, residential schools, hospitals, care homes, holiday camp chalets, day centres, services' messes |
| High hazard | The two base tests plus ignition source 7 to BS 6807:2006 | Certain hospital wards, hostels, hotels, offshore installations, care homes |
| Very high hazard | Source 7, plus any additional requirements the specifier sets | Locked psychiatric accommodation, prison cells |
Two things follow from this table, and both catch importers out.
First: "hotel quality" and "medium hazard" are not the same claim. Only one of them comes with a certificate your fire assessor and your insurer will accept. A mattress that has passed only the domestic tier — a cigarette and a match — has not been near a wooden crib test, and a hotel specification will not be satisfied by it.
Second: the category is set by the building's fire risk assessment, not by the supplier. For a hotel, serviced apartment block, student accommodation or care home, confirm the required category with the assessor or the consultant before you order, because the barrier construction that gets a bed to Crib 5 is not something you can retrofit once the beds are on the floors.
The two base tests, in plain English
EN 597-1:1994 — smouldering cigarette. A standard smouldering cigarette is placed on the sleeping surface and left. The construction must resist smouldering ignition. This is the test that catches slow, smoky ignition from dropped smoking materials.
EN 597-2:1994 — match flame equivalent. A simulated match flame is applied. The construction must resist flaming ignition.
BS 7177:2008+A1:2011 cites the 1994 versions of EN 597 specifically, even though later versions exist. If a supplier's report quotes a different edition, ask why.
Also worth knowing: both faces of a mattress must be tested unless the two faces are identical. If you are buying a two-sided build, or a mattress with a different surface on each face, budget for both surfaces being in scope.
The filling schedules
The Regulations deal with fillings separately from the finished build, and the route depends on what the filling is.
- Single fillings must pass the relevant ignition resistance tests set out in the Regulations.
- Polyurethane foam block must meet Schedule 1 Part I.
- Polyurethane foam crumb must meet Schedule 1 Part II.
- Rubber latex foam must meet Schedule 1 Part III.
- Composite fillings have two permitted routes: either every layer of the composite passes the requirement for a single filling, or the total composite passes Schedule 2 Part IV. In either case, any foam inside the composite must also meet the single foam filling requirement.
This is the part of the regime that most often goes wrong on a natural-filling bed. A mattress built from horsehair, wool, cotton and jute has no foam schedule to lean on, so the evidence has to come from the finished construction passing the hazard category you are selling it at — and, at medium hazard, from a fire-barrier or ticking decision made at the design stage.
Labelling: what a compliant label looks like
Mattresses and bed bases are not required to carry the "CARELESSNESS CAUSES FIRE" permanent label that applies to upholstered furniture. Instead, compliance is shown by a label stating conformity with BS 7177 at the relevant hazard category, and the format is prescribed:
- The word RESISTANT appears on the border in white lettering, with a minimum letter height of 5 mm
- A smouldering cigarette symbol and a flaming match symbol appear in black on the central white area
- The wording states the category — "Conforms to BS 7177 for domestic use (low hazard)", or medium, high or very high hazard as appropriate
- Labels must be positioned so they are easily seen
If a mattress carries no label at all, treat it as non-conforming until proven otherwise. Trading standards guidance is explicit that unlabelled items may not comply.
The cost nobody budgets for: repeat testing
BS 7177 is not a one-off certificate. It expects production to be re-tested on a rolling basis, so that the beds you make in month thirty are the beds you tested in month one.
| Units produced per month | Units to be tested |
|---|---|
| More than 2,400 | 1 per month |
| Between 400 and 2,400 | 1 per 2,400 units |
| Fewer than 400 | 1 every 6 months |
This is a recurring, real cost, and it is why some suppliers quietly stop testing after the initial certificate. Ask a prospective supplier how they handle repeat testing, and where it appears in the price they have quoted you. An answer that treats it as a one-time entry cost is an answer that tells you the programme will lapse.
Who is legally on the hook
This is the detail importers most often get wrong. The Regulations control goods supplied in the UK, and goods manufactured for export sit outside their scope. That means the duty does not follow the goods to the factory — it attaches to the UK supplier, importer or retailer placing the mattress on the market.
The practical consequence: your supplier cannot take your liability off you by saying they complied with Chinese standards. What they can do is give you the evidence you need — a test report for the exact construction, label artwork in the statutory format, filling documentation and batch records that trace a specific bed to a specific production run.
Decide before you order who is responsible for which part, and put it in the purchase contract. Responsibility for test evidence, label application and batch records should not be left implicit.
The five ways imports fail
- Domestic-grade evidence sold as contract-grade product. A cigarette-and-match report presented against a hotel specification that called for medium hazard.
- Fillings that were never scheduled. Foam bought on price, with no Schedule 1 Part I, II or III evidence behind it.
- Missing or non-conforming labels. Right bed, no compliant label — which is a failure on its own.
- Construction drift. The tested sample had one ticking; production shipped with a cheaper one. The evidence no longer describes the goods.
- Testing that stopped. An initial report from years ago, and no rolling programme behind it.
A procurement checklist for UK-bound mattresses
- Confirm the hazard category from the building's fire risk assessment, in writing, before ordering.
- Require a test report covering the exact construction you are buying — not the supplier's "range".
- Check the report cites BS 7177:2008+A1:2011 and EN 597-1:1994 / EN 597-2:1994, plus BS 6807:2006 if you need medium hazard or above.
- Check both faces of the mattress are covered, or that the faces are identical.
- Get filling documentation for every layer, with the schedule referenced where it applies.
- Approve label artwork in the statutory format before production, and check a sample of labels on the delivered goods.
- Agree who runs and pays for repeat testing, and at what frequency.
- Require batch traceability: model identification and batch number on every bed, and records retained.
- Freeze the construction sheet as part of the contract, so ticking and filling cannot drift.
- Require ISPM 15-treated wood packaging with IPPC marks, or your container can be stopped before it reaches the fire test.
Questions to ask any supplier quoting for the UK
Which hazard category does your report cover?
If the answer is vague, the report almost certainly covers the domestic tier only.
Can you send the report for the construction I am buying?
A report for a different build tells you nothing about yours. This one question separates real programmes from brochures.
What does reaching Crib 5 do to the feel of the bed?
An honest supplier will tell you it requires a fire barrier or compliant ticking, and what that costs you in comfort and price. A supplier who says it is free has not tested it.
How did the last three repeat tests go, and when was the last one?
This is the question that reveals whether the programme is alive.
Who applies the labels, and to what artwork?
Label failures are the cheapest kind of failure to prevent and the most common kind to find in an audit.
How we handle it
KÖPINGTOWN builds handcrafted mattresses — black horsehair, Australian wool, jute felt and calico pocket springs, closed with hand tufting and hand side-stitching. We are a manufacturer, not a testing laboratory and not a customs adviser, and we will not pretend otherwise.
What we do is scope the fire-performance construction to the hazard category you tell us you need, test the finished build through independent accredited laboratories, supply the report with the quotation, and keep the batch records that let you answer an assessor or an insurer years later. Because our beds are hand-built and never vacuum-compressed, we also give you the real pallet dimensions and loading plan, so the freight number in your business case is the number you actually pay.
