Dropshipping Sofas and Upholstered Furniture on eBay: Fabric vs Leather, Properly Explained

Why the test is on the whole sofa, not just the fabric

It is easy to assume a "fire-resistant fabric" is the whole story, but the regulations and the British Standard behind them - BS 5852 - test the assembled combination: the cover fabric, the foam or other filling beneath it, and any interliner between them, exactly as they sit together in the finished piece. A fabric that passes a test on its own, laid flat in a lab, tells you nothing certain about how it behaves once it is stitched over a specific foam inside a specific sofa. This is precisely why a genuine test certificate references a specific combination of materials, not a fabric in isolation - and it is why asking a supplier "is the fabric fire-resistant" is the wrong question. The right one is whether the whole upholstered assembly, as actually built, has been tested and passed together.

The testing itself uses two ignition sources with genuinely different severity: a smouldering source representing a dropped cigarette, and a small flaming source representing a match or lighter. Passing both is the baseline. A further, more demanding rating - commonly referred to as Crib 5, from a small stacked-timber ignition source weighing around 17 grams used to simulate something closer to a burning pile of paper - is required for contract and commercial furniture, and is often used as a marker of genuinely robust construction even on domestic pieces, though it is not the baseline domestic requirement itself. A supplier quoting a Crib 5 rating on a domestic sofa is not overstating anything - it genuinely exceeds the minimum - but it is worth recognising as a step beyond what the law actually requires for a home sale, not confusing it with the baseline every compliant sofa already has to clear regardless.

CMHR foam: what it actually is, not just a label

CMHR stands for Combustion Modified High Resilience - a polyurethane foam chemically treated during manufacture to resist ignition and slow combustion, rather than a standard foam with a compliant label applied afterwards. Genuine CMHR foam sits in a real, checkable density range, commonly quoted around 25-60kg/m³ depending on the specific grade and application. This matters for a dropshipper because "foam" on its own tells you nothing - a supplier using genuine CMHR foam throughout is making a real manufacturing choice with a real cost attached, where a supplier using an untreated standard foam and relying entirely on the cover fabric or a thin interliner to carry the whole compliance burden is taking a shortcut that may or may not have actually been tested as a real combination.

The foam inside a sofa is invisible to a buyer, and easy for a seller to never ask about at all. It is also one of the two or three things that actually determines whether the fire safety label means anything.

When an interliner is not optional

An interliner is a fire-resistant fabric barrier sewn between the cover fabric and the filling, and it is not a universal requirement - it is a specific fix for a specific gap. If a cover fabric passes the match test on its own, in combination with the foam beneath it, no interliner is needed. If it does not, a compliant interliner has to be fitted between the fabric and the filling to make the assembly pass as a whole. This is exactly the kind of detail that gets lost between a supplier's own marketing copy and what a dropshipper actually lists: two visually similar fabrics can have completely different interliner requirements underneath, and "it has the CARELESSNESS CAUSES FIRE label" does not tell you which situation you are actually looking at - only whether whatever combination was used passed its own test, interliner included or not.

Fabric versus leather: what actually differs, and what does not

Both fabric and leather-covered upholstery are tested the same way, as an assembly, against the same standard - there is no separate, lighter rule for leather. What genuinely differs in practice is the construction that tends to sit behind each. Leather itself does not ignite as readily as many fabrics under a smouldering source, which is sometimes read as leather being automatically "safer" - but the assembly as a whole, including the foam and any interliner, is still what gets tested and what the label is actually vouching for, not the top cover material in isolation. A cheaply-made leather sofa with poor foam and no interliner where one was needed is not made safe by the leather alone, any more than a well-built fabric sofa with genuine CMHR foam and a proper interliner is made unsafe by being fabric. The practical takeaway is the same for both: ask about the whole assembly, not just the surface material, because the surface material was never the whole test. This is worth remembering specifically because fabric-versus-leather is one of the most common ways a listing gets written from assumption rather than fact - it is easy to assume leather is "automatically fine" precisely because it burns less readily on its own, which is true and also beside the point the regulation actually tests for.

Asking for the actual test documentation, not just a verbal answer

A genuine manufacturer or importer supplying compliant upholstery to UK retailers should be able to produce a real test report referencing the specific fabric, foam and interliner combination used - not just a verbal assurance that "it's all fire safe." That documentation exists precisely because the regulations require the combination to have actually been tested, and a supplier who has never been asked for it before is not necessarily doing anything wrong, but a supplier who cannot produce anything at all when asked directly is a materially different situation to one who sends a specific test reference within a day. This is the same due-diligence principle covered in the general fire safety post - keeping a record of what was asked and what came back is what actually protects a seller if a compliance question is ever raised later, not the asking alone. A supplier's willingness to actually produce this paperwork, rather than deflect the question or repeat a general assurance, is itself a genuinely useful signal about how seriously they take compliance across their whole range, not just the one product being asked about.

A worked example: two fabrics, two outcomes

Take two visually similar linen-look fabrics offered by the same upholstery supplier for the same sofa frame. Fabric A passes both the cigarette and match tests in combination with the supplier's standard CMHR foam on its own - no interliner needed, and the finished sofa is compliant as built. Fabric B, chemically similar but from a different mill, fails the match test in the same combination - meaning the exact same sofa frame and foam, covered in Fabric B instead, is only compliant if a fire-resistant interliner is fitted between the fabric and the foam. A supplier who does not track this distinction, and simply ships whichever fabric a customer orders without adjusting the interliner accordingly, can produce two sofas that look identical on an eBay listing photo, one of them genuinely compliant and one of them not - which is exactly why the specific combination, not a generic assurance about the range as a whole, is what is actually worth asking about. Two products from the same supplier, sharing a frame and a foam grade, can genuinely sit on opposite sides of compliant purely because of which cover fabric ended up on each one - a detail a supplier's own catalogue rarely spells out unprompted.

What to actually ask a sofa or upholstery supplier

• Has this specific fabric-and-foam combination been tested together, and to what standard? Not "is the fabric fire-resistant" on its own.
• Is the foam genuine CMHR, and at what density? A supplier who cannot answer this specifically is a real warning sign, not a minor gap.
• Does this cover fabric require an interliner, and is one fitted? A direct yes-or-no a genuine manufacturer should be able to answer without hesitation.
• Where is the permanent label, and what does it actually list as the filling and cover materials? Covered in full in the general fire safety post, and worth checking specifically against what the supplier just told you, not taken as a separate box to tick.
• Does this apply the same way across every colourway of the same sofa? A range sold in six fabric options is not automatically one compliance answer - each cover fabric genuinely needs its own answer to the interliner question above, not one blanket assurance covering the whole range.

Why this matters for the listing itself, not just compliance

Beyond the direct safety and legal question, getting this right protects the listing in a more immediate, practical way too. A buyer who later discovers a sofa was not genuinely tested the way its label implied has a real "not as described" complaint, which - as covered in how returns and refunds actually affect your standards - counts against a seller's account specifically when eBay has to step in to resolve it. Overselling a compliance claim in a listing description - "fully fire-safety certified" written more confidently than the actual paperwork supports - is a genuinely avoidable way to turn a straightforward sale into exactly that kind of dispute, for a claim that was never necessary to make in the first place beyond stating what the permanent label itself already says. The safest wording in a listing is almost always the plainest: describing what the label states, rather than adding a confident-sounding claim on top of it that the seller has no actual way to independently verify.

Where Sellhelm fits, and where this stays yours to check

Sellhelm reads a sofa's specification, category and the supplier's own description from their page, the same as any other product - useful for keeping the material, dimensions and supplier's own claims in one place when deciding whether to list it. It does not, and should not claim to, verify whether a specific fabric-and-foam combination has genuinely been tested to BS 5852 - that is a real, physical fact about a real product, checkable only by asking the supplier directly and keeping their answer, exactly the discipline this post is about. That single check, done once per supplier's own upholstery range rather than guessed at product by product, is worth more than any amount of software polish applied around it.
