What regulations require of a convertible sofa

Two pieces of furniture in one, two sets of requirements.

For seating, the NF EN 12520 standard sets the safety, strength, and durability requirements applicable to seating for domestic use. The corresponding test methods are defined by the NF EN 1728 standard , which describes the stresses applied to the seat, backrest, armrests, and legs. For bedding, the NF EN 1957 standard applies: it defines the test methods for determining the functional and durability characteristics of beds and mattresses, including loss of height and firmness after stress.

Between the two lies the mechanism, which neither text treats as a key component. Yet it is this mechanism that experiences the most wear and tear: the repeated operation puts stress on the joints, the structure, and the connection between the seat and the base. A sofa bed intended for daily use and one intended for a few nights a year are not the same product, and the difference is not apparent in the upholstery or the seating comfort.

In establishments open to the public, the seat changes status

As soon as furniture is moved from the dwelling to a managed residence, hotel, or reception area, fire safety regulations apply. Article AM ​​16 of the decree of June 25, 1980, mandates that large furniture be classified as M3 and prohibits it from obstructing or narrowing passageways. Article AM ​​18 , specific to upholstered seating, requires an M3-rated structure, with wood at least 9 mm thick being permitted.

The same article governs seating arranged in rows: for venues accommodating more than 200 people , seats must be fixed to the floor or linked together, with a maximum of 16 seats between two aisles, or 8 when served by a single aisle. These provisions apply to halls, not individual room furnishings, but they serve as a reminder that upholstered seating is treated by the regulations as a fully-fledged element of the space.

One point deserves clarification because it is frequently confused. The test required in France is NF D 60-013 , which simulates a 20-gram burning cushion and evaluates the behavior of the entire assembly, including the cover, foam, and structure; its certification is valid for five years . The NF EN 1021-1 and 1021-2 standards , concerning cigarettes and flames, are international test methods and not a regulatory classification for public access buildings. Submitting an EN 1021 report while believing it meets the public access building (ERP) requirement is a common mistake during the acceptance phase, just like applying fire safety requirements to other types of work.

What the decree of February 19, 2026 will move

The safety regulations are undergoing a revision. The decree of February 19, 2026, amends the decree of June 25, 1980, and significantly revises the chapter on building materials, with the creation of articles AM 1-1 to AM 1-4 , as well as the provisions relating to structures and facade systems. A new article, GN 16, introduces key definitions.

The timeline allows for some time: the text enters into force on June 1 ^, 2027 , and applies to building permit applications submitted from that date onward. Articles AM 15 to AM 18, those concerning large furniture and upholstered seating, are not among the articles cited in the analyses published to date. A project owner preparing an accommodation program would therefore be well advised to check the consolidated version before submitting the application, rather than after.

The EPR scheme, an obligation for those placing on the market

Since December 2012 , furniture products have been subject to an extended producer responsibility scheme. Every producer placing furniture on the market joins an eco-organization, pays an eco-contribution that varies according to the product, and finances the collection, sorting, reuse, and recycling at the end of its life. Three eco-organizations are approved for the period 2024-2029 : Ecomaison , Valdelia , and Valobat , with a coordinating body for local authorities.

The sheer scale of the project highlights the importance of this sector. In 2024 , the industry recorded 2,8 million tons placed on the market, a collection rate of 45% , a recovery rate of 90% , and 40,000 tons reused or repurposed. For a floor-level demolition or renovation project, this means that the outgoing furniture has a clearly defined channel and a funded outlet, just as the reuse of joinery is beginning to structure the interior finishing sector.

The footprint is calculated twice

The last constraint is the simplest and most often overlooked. A convertible sofa has two footprints: closed, it occupies the space of a sofa; open, that of a bed, plus the space required for the opening mechanism. It is the second footprint that dictates the layout, since it is this footprint that must allow for movement within the space. The piece of furniture transforms a living room into a spare bedroom, and this transformation cannot be reflected in a floor plan that only shows the sofa in its folded state.

Access is another consideration. A sofa bed is delivered in one piece, and its size must allow it to fit through the front door, the stairwell, and any pocket doors . This is an interior design issue before it's a purchasing decision.

Furniture remains the neglected element in building design. It arrives after the initial setup, on an equipment line, despite carrying safety requirements, end-of-life responsibilities, and a geometry that constrains the overall plan. The same observation applies to integrated artwork : what enters the building after construction is best decided upon during the planning phase.
