The mattress is the one piece of furniture a guest judges with their body, and it ends up in the review in precise words. Nobody writes that the bedside table was uncomfortable. We supply mattresses for hotel use in certified fire class 1 IM and with foam density no lower than 35 kg/m³, with floor-by-floor delivery, collection of the old mattresses and disposal to standard. On a 50-room property, a full replacement is carried out in two days without stopping sales.
Density and load rating: the two numbers that matter
Foam density is what separates a hotel mattress from a mass-market one, and almost no commercial data sheet highlights it. A polyurethane below 30 kg/m³ loses height and support within eighteen months of continuous use: a hollow forms in the centre, the guest sleeps in a dip, and the review about the sunken bed follows.
For hotel use, the reasonable minimum is 35 kg/m³ on the supporting layer. On memory foam, which sits above the core, the threshold rises to 50 kg/m³, because below that value the viscoelastic foam collapses and doesn’t spring back into shape. A 4 cm layer of memory foam at 50 kg/m³ costs the same as a 7 cm layer at 40, and lasts twice as long.
On pocket springs, the number to look at isn’t the total but the density per square metre. A 160×200 double with 800 springs works out to around 500 per square metre, a good contract figure. Versions with 500 springs on a double have too wide a mesh and give that “old mattress” feel guests describe even when the mattress is brand new.
The declared load rating should reach at least 120 kg per sleeping position, not because every guest weighs 120 kg but because a mattress sized right at the limit is always working under maximum flex and gives out sooner. Usable height sits between 22 and 26 cm on polyurethane mattresses and between 24 and 30 on sprung ones, beyond which making the bed becomes hard work.
Fire class 1 IM isn’t optional
A hotel mattress is an upholstered item and falls under the obligation for fire class 1 IM. It isn’t a recommendation: it’s a condition for operating, checked during fire brigade inspections alongside armchairs, upholstered headboards and sofas.
What the fire safety file needs is the product’s approval paired with the supplier’s declaration that that batch matches that certificate, reference numbers included. A “fire-resistant” mattress with no approval number is worthless at inspection. The logic behind how fire class 1 IM is proven on upholstered furniture applies just the same to a mattress as to the armchair in the room.
One point that generates disputes: if the mattress is approved but covered with a mattress protector that isn’t certified, the whole system can be considered compromised at inspection. We therefore supply mattress protectors with matching certification.
Types of mattress for hotel use
Pocket springs with a comfort layer
The most solid choice for four-star properties. Independent spring core, 500 springs per square metre or more, with a layer of polyurethane or memory foam on top. It breathes well, a real advantage in rooms closed up for days, and distributes weight independently across both sides of a double bed. Useful hotel life of eight to ten years.
High-density waterfoam
Water-blown polyurethane foam core, density 35 to 40 kg/m³, height 22 or 24 cm. Costs less, weighs less, and is easier for housekeeping staff to turn. It’s the right solution for seasonal properties and three-star hotels. The drawback is breathability, which needs to be offset with a technical fabric cover and a ventilated slatted base.
Zoned support mattress
Seven support zones, with firmer support at the lumbar band and softer give at the shoulders. Makes sense in superior rooms and in properties that treat sleep as part of their positioning. It does need one precaution: the zones only work if the mattress is oriented correctly, so rotation has to be head to foot, never flipped over, and staff need to be trained on it.
Mattress for extra beds and sofa beds
Reduced height between 14 and 18 cm, density still no lower than 30 kg/m³. It’s the mattress people always try to save money on, and the one that gets the worst reviews, because it’s almost always a child sleeping on it, accompanied by a parent who then writes the review.
Topper
An additional layer 4 to 6 cm thick, in memory foam or fibre, laid on top of the mattress and held in place with elasticated corners. It serves two purposes: it raises perceived comfort without touching the core, and it’s replaced every two or three years, taking on the wear instead of the mattress. In a well-run property it’s the disposable component of the bed system.
Rotation, protection, replacement
A hotel mattress should be rotated head to foot every three months. On double-sided models, flipping is added twice a year, whereas on single-sided models, now the majority, flipping crushes the comfort layer on the wrong side. A rotation schedule pinned up in the housekeeping room costs nothing and adds two or three years to the life of the mattress stock.
A waterproof, breathable mattress protector, polyurethane bonded to cotton jersey, is the room’s best-value spend. It costs between 15 and 30 euros, washes at 60 degrees, and stops a night-time accident from sending a 250-euro mattress to the skip. With high guest turnover, we use the zip-around encasement version, which also protects the sides and shuts the door on bed bugs.
Replacement should be planned on cycles, not on failure. Eight years for sprung mattresses, six for waterfoam, three for toppers, with an annual check on a sample of rooms. Replacing on failure means always having a share of rooms with mattresses that are already unacceptable, and it’s the reason certain properties can’t shift their bed comfort score: on the thresholds for when to change a hotel’s mattresses, it’s worth building a table and sticking to it.
A mattress alone doesn’t make the bed
An excellent mattress on a tired base performs like a mediocre one. The base has to be rigid and flat, and in hotels the most reliable solution remains a hotel divan base with a timber frame and sprung deck, which supports the whole surface rather than resting on twenty contact points.
Measurements matter too. A hotel single is 90×200, no longer 80×190, a double sits at 160×200 with a trend towards 180×200 in higher categories, and two singles pushed together need a bridging connector if the room is also sold as a double. Getting this wrong costs you in new linen, so standard hotel bed sizes should be fixed before ordering.
The combination of a rigid base, the right mattress, a topper and freshly pressed linen is what makes hotel beds comfortable, more than any technology quoted on a spec sheet. For a quote we need the number of rooms by type, current measurements and an approximate delivery date: you can request one here, collection and disposal of the old mattresses are included.
Frequently asked questions
How often should a hotel’s mattresses be changed?
Eight years for pocket-sprung models, six for high-density polyurethane ones, two or three for toppers. The practical test is checking elastic recovery on a sample of rooms every year: if a mattress keeps a body impression or shows a visible central dip once the bed is stripped, it should be replaced without waiting for the theoretical deadline.
Is a fire-resistant mattress less comfortable?
No. Fire class 1 IM is achieved with internal fire barriers and treated fibres in the cover, not by stiffening the core, so comfort stays intact. The surcharge for certification is around 10%.
Is it worth putting a topper on every bed?
In four-star properties and above, yes, because it raises perceived comfort and absorbs wear instead of the mattress, which costs ten times as much. In seasonal three-star properties it makes less sense, because it adds another item to manage in the laundry and lengthens the time it takes to make the bed.
Do you collect and dispose of the old mattresses?
Yes, and it’s organised alongside delivery, with a disposal form for the property. On a 50-room job we work floor by floor: in the morning the rooms on that floor are cleared, in the afternoon the new mattresses are delivered, by evening the rooms are back on sale.
