Furniture strength and durability standards map

At a glance

Editions as listed on 5 November 2026 (BSI Knowledge, or a standards seller where marked in the editions table). 'Named, to confirm' means a test house names the standard but its role and edition were not checked. Every edition changes: check before you specify.

How the standards are organised

Three kinds of document sit in the map, and mixing them up is the commonest mistake in a specification.

• Requirements standards say what a product must pass, for one type of furniture in one kind of use. BS EN 16139 for non-domestic seating and BS EN 12520 for domestic seating are the pair for chairs; BS EN 15372 and BS EN 12521 are the pair for tables; BS EN 16121 and BS EN 14749 for storage. Several give a user-weight basis in their scope: the BSI and seller listings for BS EN 16139, BS EN 12520, BS EN 1725 and BS EN 1335-2 all state adults up to 110 kg.
• Test-method standards say how to test. BS EN 1728 (seating) and BS EN 1730 (tables) are listed by BSI as test methods only: BS EN 1728 “does not include any requirements”, and BS EN 1730 sets no requirements either. Specify the requirements standard, which calls up the method, not the method alone.
• What sits outside. Fire, upholstery and fabric wear, finishes, mechanisms, electrical safety and comfort are covered, if at all, by other documents. See the section on what the standards leave out.

Some standards run on severity. BS EN 16139 tests at Level 1 (general use) or Level 2 (extreme use), explained on our BS EN 16139 sheet. Where a standard has levels, a specification has to name the level: a standard number alone is not enough. Whether other standards in the map vary requirements by severity or application is not covered by anything we read.

The map, and how to choose between domestic and non-domestic

Read across for a furniture type. Where one box spans both columns, a single standard covers domestic and non-domestic use: adult beds in BS EN 1725:2023, outdoor seating and tables in BS EN 581, and office furniture (chairs in BS EN 1335, desks in BS EN 527), which sits in its own family and is excluded from the general seating and table standards.

• Choose by use, not by who buys it. A private home is domestic. A hotel, restaurant, bar or office is non-domestic. For mixed premises, such as a serviced apartment or a members' club with residential rooms, ask the client and the test house which applies. None of the listings read defines ‘non-domestic’ for you.
• Office is separate. The BSI listing for BS EN 16139 excludes office work chairs, ranked seating, chairs for educational institutions and outdoor seating; the BSI listing for the 2016 edition of BS EN 15372 excludes office work tables and desks and outdoor tables with their own EN standards. Each has its own standard.
• A bespoke piece needs its own evidence. A test report applies to the item tested. If a bespoke design has no report, agree with the partner workshop how it will be evidenced, for example a representative sample tested at an accredited laboratory before production, and who pays and when.
• Built-in items are not settled. Nothing read says how these standards treat a built-in banquette, window seat or fitted storage. Ask the test house before claiming compliance for them.

Editions seen on 5 November 2026

Each line is dated. Where BSI Knowledge shows the standard we say so; where only a standards seller does, the line says that too. Test-house and seller pages go out of date: one test house's service pages we read still listed BS EN 16139:2013, BS EN 15372:2016, BS EN 12520:2015 and BS EN 16121:2013+A1:2017, which BSI shows as withdrawn or replaced, and BS EN 1725:1998 as the domestic bed standard. That is a list of what a laboratory can test, not a claim that it cannot test to the new editions, but it shows how easily an edition goes stale. Quote the number and the year, and check BSI Knowledge on the day.

FIRA publishes quarterly standards and regulatory updates for members, which would be the right source for refreshing this table; the March and May 2026 pages are members-only and were not read. Update this table at every review and at least quarterly.

What these standards leave out

The scope text on the listings read is consistent about what falls outside. Treat each of these as a separate line in the specification, with its own evidence.

• Fire. Most of the listings read say the standard does not cover flammability. Fire performance of upholstery is handled by the 1988 Regulations for domestic furniture and by the fire risk assessment and BS 7176 for non-domestic premises: see the BS 7176 and fire documentation sheets.
• Upholstery, castors and mechanisms. The listings for BS EN 16139, BS EN 12520 and BS EN 581-1 exclude the durability of upholstery materials, castors, reclining and tilting mechanisms and seat height adjusters.
• Ageing and degradation, and electrical safety. Excluded in most of the listings read for the seating, table, storage and bed standards.
• Comfort and ergonomics. A standards-seller listing for BS EN 12520:2024 says ergonomics is not covered, and BS EN 1728 is test methods only. Comfort is agreed on a prototype: see the sit-test protocol.
• The building. A seller listing for BS EN 15372:2023, whose scope text appears garbled, says strength requirements do not extend to building structures, with a wall-hung unit covered for the unit and its attachment parts, not the wall. Whatever the standard says, who checks the wall and the fixing is a separate decision.
• Surface finish and fabric wear. Surface-resistance methods for furniture (EN 12720, 12721, 12722, 15186) and Martindale abrasion for fabrics (EN ISO 12947-2) are separate documents. See the contract versus domestic checklist.
• Accessibility. Dimensions and clear space for disabled users come from Approved Document M and BS 8300, not from these standards: see Approved Document M for furniture and joinery.

Are these standards the law, and what to write in a specification

We found no law that names any of these standards as mandatory for furniture. Three things sit around them.

• Articles for use at work. Section 6(1) of the Health and Safety at Work etc. Act 1974 puts a duty on anyone who designs, manufactures, imports or supplies an article for use at work to ensure, so far as is reasonably practicable, that it is safe, to carry out or arrange such testing and examination as may be necessary, and to give adequate information about its use. The Act names no standard; testing to the relevant standard is a common way of evidencing the duty.
• General product safety. Regulation 5 of the General Product Safety Regulations 2005 says no producer shall place a product on the market unless it is a safe product. Regulation 6 gives a presumption of safety to a product that conforms to a standard the Secretary of State has considered appropriate and published for the purpose. We have not checked whether any furniture strength standard is on that list.
• Fire. A FIRA summary says that only the tests required by the Furniture and Furnishings (Fire) (Safety) Regulations are legally mandatory, that all furniture must meet the General Product Safety Regulations, and that testing to the most relevant standards is the best way to show compliance.

So a standard is evidence, not a licence. In a specification, name five things: the standard and year, the level or severity where one exists, the exact model and variants, a full signed report from a laboratory accredited to ISO/IEC 17025 (in the UK, accredited by UKAS), and the date of the report. Reports to a withdrawn edition, or for another model, do not count. The wording below is a starting point.

[Product type] is to be supplied with the full signed test report from a laboratory accredited to ISO/IEC 17025 for the tests named, showing compliance with [standard number and edition] [at Level / severity ] for the exact model and variants supplied, dated within [ ] months of order. Reports to a withdrawn edition, or for a different model, are not accepted. The designer will confirm the current edition on the BSI website before order and the supplier is to be told of any change.

Seating to BS EN 16139:2025, Level [1 general use / 2 extreme use]. Tables to BS EN 15372:2023 [at the test severity agreed with the client]. Storage to BS EN 16121:2023. Beds to BS EN 1725:2023. [Edition and status to be re-checked on BSI Knowledge before order.] Each is evidenced as in the evidence clause. Fire, upholstery wear, finishes and mechanisms are specified separately.

Office work chairs to BS EN 1335-2 [edition], office desks to BS EN 527-2 [edition], outdoor seating and tables to BS EN 581-1 with BS EN 581-2 (seating) and BS EN 581-3 (tables) [editions to be confirmed], domestic seating to BS EN 12520 [edition], domestic tables to BS EN 12521 [edition]. Each is evidenced as in the evidence clause.

Where an item is bespoke and no report exists, the supplier shall [have a representative sample tested to [standard and edition] [Level / severity ] at an accredited laboratory before production / provide [ ] as agreed with the client] and submit the report before the production order is released. Cost and programme for the test are to be agreed before order.

Questions we are asked

Which standard applies to a restaurant chair?

BS EN 16139:2025, the standard for non-domestic seating, at Level 1 (general use) or Level 2 (extreme use) as agreed with the client. An office work chair has its own standard, BS EN 1335-2, and BS EN 12520 is the domestic seating standard.

What is the difference between BS EN 12520 and BS EN 16139?

BS EN 12520 is for domestic seating and BS EN 16139 for non-domestic seating. Both are listed for adults up to 110 kg and both leave out upholstery durability, castors, mechanisms, ageing and flammability. A report to one is not a report to the other.

Do I specify BS EN 1728 or BS EN 1730?

Not alone. They are test-method standards and, on their BSI listings, set no requirements. Specify the requirements standard for the furniture type, which calls up the method, and ask for the report.

Is there a standard for hotel beds?

BS EN 1725:2023, as listed by BSI, covers fully assembled adult beds in domestic and non-domestic environments, for users up to 110 kg. Bunk, high and medical beds are excluded from its scope. Older test-house pages still name the 1998 edition and a FIRA standard for contract beds, so confirm which applies.

Does testing to a standard make a product legal or safe?

A standard is evidence, not a licence. We found no law that names these standards as mandatory for furniture; general safety duties apply to articles for use at work and to consumer products, and the standards are a common way to show them. Fire is separate.

Which standard covers a banquette or built-in seat?

Nothing read settles it. BS EN 16139 covers non-domestic seating; how it treats a fixed, built-in seat is for the test house and the partner to advise. Do not claim compliance for built-in items without that advice.

How do I keep the edition up to date?

Check BSI Knowledge on the day you specify, quote the standard number and the year, and ask the supplier for a report to the edition in force. FIRA publishes quarterly updates for members.
