Fire safety is not glamorous, but it is one of the non-negotiable parts. Every piece of upholstered furniture sold, supplied, or reupholstered in the UK must comply with fire safety regulations. Getting it wrong is not just risky: it is illegal.

Whether you are buying new furniture, having something reupholstered, or running a commercial premises.

The Regulations: A Quick Summary

The key legislation is the Furniture and Furnishings (Fire Safety) Regulations 1988 (as amended in 1989, 1993, and 2010). These regulations apply to all upholstered furniture intended for use in a private dwelling in the UK, including:

Sofas, armchairs, and dining chairs
Beds, headboards, and mattresses
Cushions, pillows, and seat pads
Garden furniture suitable for indoor use
Nursery and children's furniture

The regulations require that the filling materials and the cover fabric (or an interliner between them) pass specific ignition tests. The goal is to slow the spread of fire in upholstered furniture, giving people more time to escape.

What the Tests Actually Measure

Cigarette Test (Ignitability Source 0)

A simulated smouldering cigarette is placed on the fabric and filling combination. The assembly must not ignite progressively. This tests resistance to smouldering ignition, which accounts for a significant proportion of furniture fires.

Match Test (Ignitability Source 1)

A simulated match flame (a butane flame applied for 20 seconds) is held against the fabric. The cover fabric must resist ignition from this small open flame. If the fabric itself does not pass, a compliant interliner must be used between the fabric and filling.

Filling Tests

All filling materials (foam, polyester wadding, feathers, fibre) must meet specific ignitability standards. Polyurethane foam, for example, must pass the ‘Crib 5 equivalent’ test for combustibility modified foam (CMHR foam). Traditional fillings like horsehair and cotton have their own test requirements.

What Is Crib 5?

You will often hear “Crib 5” mentioned in commercial upholstery. Crib 5 (BS 5852) is a more stringent fire test that uses a larger ignition source: a wooden crib (small stack of wooden sticks), to test how the complete fabric and filling assembly performs under sustained flame.

Crib 5 compliance is required for:

Hotels, B&Bs, and serviced accommodation
Restaurants, pubs, and bars
Care homes and hospitals
Offices and commercial waiting areas
Student accommodation
Any furniture in a public or commercial building

If you are having commercial upholstery work done, Crib 5 compliance is not optional. We always use Crib 5 rated fabrics and fillings for commercial projects and can provide compliance certificates for your records.

Domestic vs Commercial: The Key Difference

For domestic (home) furniture, the standard tests (Source 0 and Source 1) are the legal minimum. Most domestic-grade fabrics from reputable suppliers pass these tests or can be used with a compliant interliner.

For commercial premises, Crib 5 is the standard. This limits fabric choice somewhat, as not all fabrics are available in Crib 5 rated versions, but the range has improved in recent years. Most major fabric suppliers now offer Crib 5 options in their popular ranges.

Filling Material Fire Ratings Compared

Not all filling materials behave the same way in a fire. Here is how the common upholstery fillings compare:

Filling Material	Fire Performance	Passes Domestic Regs?	Notes
CMHR foam	High resistance	Yes (standard)	Industry default for compliant upholstery. Self-extinguishes when flame source is removed.
Standard polyurethane foam	Poor	No	Burns fast, produces thick toxic smoke. Banned in UK upholstery since the 1988 regulations.
Polyester wadding	Moderate	Varies by grade	FR-treated polyester passes. Untreated polyester melts and drips, spreading flame.
Feather/down	Good natural resistance	Yes (with casing)	Feathers resist ignition well. Must be enclosed in a downproof casing that also passes testing.
Horsehair	Good natural resistance	Yes	Chars rather than burns. Traditional filling with good fire properties, used in period restorations.

CMHR foam is the workhorse of modern compliant upholstery. We use it as standard on all domestic and commercial work. For traditional restorations where horsehair or feather fillings are appropriate, those materials have their own test requirements, and we ensure every combination passes before the piece leaves the workshop.

The Interliner: What It Is and When We Use It

An interliner (also called FR barrier cloth) is a layer of fire-retardant fabric fitted between the cover fabric and the filling. It is a tightly woven material, usually white or grey, treated with fire-retardant compounds. The interliner acts as a shield: if the cover fabric ignites from a match or cigarette, the barrier cloth prevents the flame from reaching the filling underneath.

We use an interliner in two situations. First, when the customer's chosen cover fabric does not independently pass the Source 1 match test. Many natural fabrics (cotton, linen, silk) fall into this category. Second, when the fabric supplier has not tested the specific fabric to the required standard and cannot provide a test certificate.

The interliner sits flat against the filling, beneath the cover fabric. It does not affect the feel or appearance of the finished piece. You would not know it was there. On a typical armchair, adding an interliner adds around £30–£50 to the job, a small cost for legal compliance and genuine safety.

For Crib 5 commercial work, an interliner alone is usually not sufficient. The cover fabric itself must be Crib 5 rated, or a Crib 5 barrier must be used in combination with tested fillings. We always specify the correct combination for commercial projects.

What About Reupholstery?

When we reupholster a piece of furniture, the finished result must comply with current fire safety regulations. This means:

We use CMHR (Combustion Modified High Resilience) foam as standard, which meets the required ignitability tests.
If the cover fabric does not independently pass the match test, we add a fire-retardant interliner between the fabric and filling.
For commercial work, we source Crib 5 rated fabrics and fillings.
We can provide compliance labels for the finished piece, confirming it meets the relevant regulations.

This is one area where using a professional upholsterer rather than attempting DIY matters. A non-compliant piece of furniture is not just a personal risk. If you were to sell it or if it were involved in a house fire, there are serious legal implications.

Penalties for Non-Compliance

The fire safety regulations are enforced by local Trading Standards officers. They have the power to inspect furniture retailers, upholsterers, and manufacturers, and to test products for compliance. The consequences of selling or supplying non-compliant furniture are serious:

Fines up to £5,000 per itemunder the Consumer Protection Act. That is per piece of furniture, not per batch. Ten non-compliant dining chairs means up to £50,000 in potential fines.
Criminal prosecution. Supplying non-compliant furniture is a criminal offence, not a civil matter. Directors and sole traders can be held personally liable.
Product recall and seizure. Trading Standards can seize non-compliant stock and require you to recall items already sold.
Insurance implications. If a fire involves non-compliant furniture that you manufactured, supplied, or reupholstered, your insurance may not cover the claim. The same applies to landlords furnishing rental properties with non-compliant items.

For landlords, this is a particular concern. All upholstered furniture in a rental property must comply with the regulations. If you are furnishing a buy-to-let or an HMO, every sofa, armchair, and mattress you provide must carry a compliance label. Local authorities check for this during inspections, and non-compliance can affect your licence.

Common Questions

Do antique or vintage pieces need to comply?

Furniture manufactured before 1950 is exempt from the regulations in its original state. However, if you reupholster an antique, the finished piece must comply with current regulations. The exemption only applies to the original upholstery.

What about fabric I supply myself?

If you source your own fabric, we will check its fire rating before proceeding. If it does not pass the Source 1 match test, we will add an interliner. We will always advise you before starting work if there are compliance considerations with your chosen fabric.

Are there labels I should look for?

All compliant furniture sold in the UK should carry a permanent label (sewn in or stapled to the base) stating that it meets the requirements of the Furniture and Furnishings (Fire Safety) Regulations. When we complete a reupholstery job, we attach an updated compliance label.

What about outdoor furniture?

Furniture designed exclusively for outdoor use is exempt. However, if it is “suitable for use in a dwelling” (for example, conservatory furniture that could reasonably be used indoors), it must comply.

Why This Matters

Around 200 people die in fires in England each year, according to Home Office statistics. Upholstered furniture is involved in roughly 45% of accidental dwelling fires where the source of ignition can be identified. That makes sofas, armchairs, and mattresses the single largest category of items involved in fatal house fires.

The reason is straightforward: standard polyurethane foam burns fast, produces thick black smoke containing hydrogen cyanide and carbon monoxide, and can turn a small ignition source into a room fire in under three minutes. CMHR foam and compliant interliners slow that process down, buying occupants the extra minutes needed to escape or for smoke alarms to sound before conditions become unsurvivable.

Before the 1988 regulations, furniture fire deaths in the UK were far higher. The regulations have prevented an estimated 1,400 deaths and 7,000 injuries over the decades since introduction. That is the practical reason these rules exist: they save lives, in measurable numbers, every year.
