The reference thresholds exist, and here they are: from 25,000 Martindale cycles upwards for seating in guest rooms, from 40,000 for the lobby and lounge, from 50,000 to 60,000 for the restaurant and breakfast room, plus Class 1 IM fire reaction certification on all upholstered pieces, required in hospitality premises by Ministerial Decree (DM) 9 April 1994. These are useful numbers for writing a specification, and indeed everyone asks for them. The question that remains unanswered, though, and the one that actually decides the budget, is a different one: where it’s worth spending and where a higher number achieves nothing. We get to that at the end, after setting out what those figures actually measure.

What the Martindale test measures (and what it doesn’t)
The test rubs a sample against a standard abradant following a Lissajous figure, a figure-of-eight motion that reproduces rubbing in every direction. The result is the number of cycles the fabric withstands before two threads break or visible wear appears.
Two points that matter a great deal in practice. First: the test measures abrasion and nothing else. It says nothing about tear strength, seam strength or colour fastness. A fabric rated at 100,000 cycles can fade within six months in front of a south-facing window and still remain compliant with its technical data sheet.
Second: beyond a certain threshold, the figure saturates. Between 50,000 and 100,000 cycles, on a bedroom armchair, the practical difference tends towards zero, because that armchair will be replaced for aesthetic reasons long before the covering wears out. On a breakfast-room chair used four sittings a day, by contrast, the same difference is visible to the eye after two seasons.
Recommended Martindale cycles by area
| Area | Recommended Martindale | What drives the choice |
|---|---|---|
| Headboards and vertical upholstery | 20,000-25,000 | Minimal rubbing, cleanability matters |
| Armchair or chair in the room | 25,000-35,000 | Intermittent use, one guest at a time |
| Sofa bed in room or suite | 35,000-45,000 | Mechanical stress from folding out |
| Lobby and lounge | 40,000-50,000 | Waiting, luggage, continuous use |
| Breakfast room | 50,000 | Food and drink, stain resistance is the priority |
| Restaurant and bar | 50,000-60,000 | More sittings, rubbing between chair and table |
| Meeting rooms | 40,000-50,000 | Concentrated use over few days |
These remain general indications. A 40,000-cycle fabric with a tight weave and a robust yarn can hold up better than a 60,000-cycle fabric with an open structure, because the construction counts for as much as the figure on the data sheet.
Class 1 IM: why it covers the whole assembly, not just the fabric
Armchairs, sofas, seating with upholstered backrests and headboards in hospitality premises must be certified as Class 1 IM. The letters IM stand for imbottito (upholstered), and the classification covers the combination of covering and padding tested together.
This is the most costly misunderstanding around. A hotelier buys a certified fabric, takes it to an upholsterer who applies it to whatever padding is at hand, and believes the result is certified upholstery. It isn’t: the certification is valid for the specific assembly that was tested. Changing the padding, the supporting frame or the type of stitching invalidates it.
The obligation for hotel and tourist accommodation premises stems from Ministerial Decree (DM) 9 April 1994. Premises with more than 25 beds also fall among the activities subject to Fire Brigade inspection under Presidential Decree (DPR) 151/2011, activity no. 66, and must keep the documentation available.
Flame-retardant fabric: inherent in the fibre or treated afterwards
Two routes lead to the required fire-reaction class, and they differ chiefly in how they hold up over time.
In an intrinsically flame-retardant fabric, the property lies in the fibre itself: FR polyester, Trevira CS, wool with a low flame-spread structure. It isn’t lost through washing and doesn’t decline with age.
With a fabric treated afterwards, an ordinary fabric is impregnated with a flame retardant. It works, and it costs roughly 20 to 35% less to buy, but the treatment wears off: typically after a certain number of washes, or in any case within a few years. It then needs renewing and recertifying, with recurring costs and a real documentation risk, because a treatment that has expired at the time of an inspection leaves the property non-compliant. Over a ten-year horizon, the economic comparison almost always flips.
Fibres for contract fabrics: FR polyester, chenille, faux leather and wool
FR polyester is the workhorse of contract fabrics: permanently flame-retardant, excellent colour fastness, good abrasion resistance, cleanable with water-based detergents, and reasonably priced. Its limitation lies in the handle, because the cheaper versions have a plasticky feel that’s obvious the moment you touch them.
Chenille has a short pile woven into the weft, a warm handle and a rich appearance, but it tends to flatten at seating points and show shine, so it works better on headboards and vertical upholstery than on high-turnover seating.
Polyurethane faux leather in the lobby, breakfast room and restaurant is often the most rational choice: it wipes clean with a cloth, resists food stains, and is available with high Martindale ratings and proper certification. Two characteristics need to be requested in writing, though. Hydrolysis resistance, because the cheaper versions crumble in hot or humid environments within three to five years. And compatibility with alcohol-based disinfectants: many standard faux leathers turn dull or crack on armrests if cleaned repeatedly with alcohol.
Wool and wool blends have a naturally favourable fire reaction and a handle that no synthetic fibre matches. They cost roughly two to three times as much as FR polyester, stain more easily and don’t tolerate aggressive cleaning: they make sense in suites and in the hotel lobby of an upmarket property, much less where breakfast is served.
Colour fastness to light and rubbing
Colour fastness to light is measured on a scale of 1 to 8. For contract use, the reasonable minimum is 5, rising to 6 or more for anything within three metres of a window, on a veranda or under a pergola. Colour fastness to rubbing, both dry and wet, uses a scale of 1 to 5 instead: below a rating of 4, the colour transfers onto guests’ clothing, which generates immediate complaints. It should be requested in particular for dark, saturated fabrics, with intense blues and reds top of the list.
In seafront properties, strong light and salt air accelerate degradation more than expected: two seasons are enough to shift the colour of a fabric rated 4.
Stain-resistant treatments and internal barrier membranes
Water- and oil-repellent treatments create a surface barrier that buys time to act before a liquid soaks in, roughly a few minutes to half an hour, not full waterproofing. On restaurant and breakfast room seating, they pay for themselves at a typical surcharge of 10-20%, a cost the first spilled cappuccino recovers.
Often more effective than the treatment is an internal barrier membrane, fitted between the covering and the padding, which stops liquids before they reach the polyurethane. It’s what saves a sofa bed once a liquid has already got through the fabric, and on sofa beds for hotels it needs to be requested explicitly, because it’s almost never included as standard.
Removable or fixed covers: what changes in day-to-day management
On hotel armchairs and communal-area seating, removable cushion covers change routine management: a cover with a zip can be washed or replaced without taking the piece out of service, while a fixed covering requires an upholsterer and days out of use.
There is, however, a constraint worth keeping in mind: washing a cover can alter its fire-reaction properties if the fabric is treated rather than intrinsically flame-retardant. Anyone choosing removable covers has one more reason to stick with permanent FR fabric.
One last practical recommendation: keep at least one spare set of covers in stock for every ten pieces of each seating model. Items go out of production and dye lots change, so reordering three years later almost always means finding a different shade, with the consequences described in the guide on spare parts and finishes.
Which certificates and documents to keep on site
Four documents, plus one conditional one. The certification document with its number, for each upholstered piece. The manufacturer’s declaration of conformity. The fabric’s technical data sheet, with Martindale rating, composition, colour fastness and weight per square metre. The batch reference together with the commercial name, essential for reordering. If the fabric is treated, also the treatment date and expiry.
A practical tip: photograph everything and keep a digital copy in the cloud. When management changes hands, paper files disappear with surprising frequency, and reconstructing a certification after the fact is expensive.
Where it’s worth spending the fabric budget
Back to the opening question. The answer doesn’t lie in a single number but in a distribution, and the criterion is seating turnover, meaning how many different people use that piece in a day.
In guest rooms, turnover is very low: one guest at a time, few hours of actual sitting. There, the budget should go on the fabric’s handle and cleanability, with Martindale ratings at the lower end of the table. In the breakfast room and restaurant, turnover is at its highest and the risk is food-related: that’s where the high cycle counts, stain treatment and mid-tone colours are needed, because very pale solid colours and black are the two hardest extremes to maintain, while melanges and close two-tone weaves mask stains and wear for years. In the lobby, the risk is mixed and the fabric is also part of the image, so it’s the only area where it makes sense to pay for appearance, provided you don’t drop below the thresholds.
The quickest way to waste budget is the opposite approach: 100,000 cycles in the bedroom because it looks good on the specification, and savings on the breakfast chair, which will wear out first.
Frequently asked questions about contract fabrics for hotels
How many Martindale cycles are needed for hotel seating?
Roughly 25,000-35,000 for bedroom armchairs and chairs, 40,000-50,000 for the lobby and lounge, 50,000-60,000 for the restaurant and breakfast room. Above these thresholds, the practical benefit shrinks considerably, because furnishings are replaced for aesthetic or restyling reasons long before the covering wears out.
What’s the difference between an inherently flame-retardant fabric and a treated one?
In the first, the property lies in the fibre itself and doesn’t decline over time or through washing. In the second, the fire reaction comes from a product applied to the surface, which wears off and requires periodic renewal and recertification. For contract use, the intrinsic version costs more to buy and less over the whole life cycle.
Is Class 1 IM certification mandatory in hotels?
Yes, for upholstered furniture in hotel and tourist accommodation premises, under Ministerial Decree (DM) 9 April 1994. The certification covers the combination of covering and padding, not the fabric on its own. Premises with more than 25 beds also fall among the activities subject to Fire Brigade inspection under Presidential Decree (DPR) 151/2011, activity no. 66.
Can I buy the fabric myself and have it fitted?
It’s possible, but it needs to be handled formally. Applying a certified fabric to whatever padding is available doesn’t produce certified upholstery, because the test covers the specific combination. The seating manufacturer needs to accept the customer’s fabric and have the assembly certified, otherwise the property ends up with a certificate that doesn’t cover the furniture actually installed.
Is faux leather suitable for a hotel?
Yes, and in the breakfast room and restaurant it’s often the best choice for ease of cleaning. Two characteristics need to be explicitly stated on the data sheet: declared hydrolysis resistance, to avoid crumbling in hot, humid environments after three to five years, and compatibility with alcohol-based detergents, which many standard versions lack.
What happens if I wash the covers on upholstered furniture?
If the fabric is intrinsically flame-retardant, washing doesn’t alter its fire reaction, provided the care instructions are followed. If it’s treated afterwards, however, washing can reduce or eliminate the treatment’s effectiveness, meaning the upholstery no longer complies with what was certified. For removable-cover furniture, permanent FR fabric is always the better choice.
How much fabric stock is it worth ordering?
As a rule of thumb, one set of covers for every ten pieces of each seating model, plus one or two metres of fabric for every item used on fixed upholstery. These should be kept together with the batch reference and the certification documentation: without the batch number, even finding the same article again risks a visible shade difference.
