What is Cold Foam Mattress

Cold foam is the high-tech foam of the moment that, especially for mattresses, offers great properties. The open cell structure that has cold foam naturally ensures that the material ventilates well and allows moisture to pass through well. The open cell structure also ensures that a cold foam remains relatively cool.

Silage formation is rare with good cold foam mattresses. However, a print of the sleeper may occur, but this does not hurt support or comfort. The material offers a lot of comforts and has a very long service life. Cold foam mattresses are generally good mattresses with high-quality properties. However, the price and quality differences are substantial, making it difficult to find a perfect cold foam mattress. Below I will tell you what you can pay attention to and where to go.

Good cold foam mattresses last a long time and offer a lot of support and comfort. High-quality Cold Foam is elastic and therefore has a high corrective capacity. That is the mattress’s ability to adapt to the body in such a way that the body receives sufficient support everywhere. The cold foam also offers good progressive back pressure (the more you press the foam, the more back pressure it gives). Progressive backpressure is essential for a good mattress. Only then can a mattress really offer support.

What’s good cold foam? Perfect cold foam has a good Polyol ratio, a relatively high HR value, good density, and comes from an excellent foam manufacturer. The best HR value for cold foam mattresses is HR 50, 55, 60 or 65 (HR = High Resilience). Lower than HR 50 is better avoided, as this makes the foam slacker and weeper. A perfect cold foam mattress is, without a doubt, the Comfort Premium Air. This is even an HR65 cold foam mattress with an all-natural Tencel mattress tack (textile)!

 

Quality differences between cold foam

cold foam mattress

Cold foam is a great material that offers a lot of resilience, ventilation and comfort. However, there are huge quality differences and, therefore, also price differences. But where do the price differences and quality differences come from? How do you see or notice the quality differences when purchasing? Usually, you can see it in the prices that are requested for cold foam mattresses. You can already buy a cold foam mattress for €200,- but also a similar cold foam mattress in the same thickness etc., that costs €800-. How do you know if you are buying a really good or bad cold foam (mattress)? Usually, you can assume that a price fighter mattress or a supplier who wants to supply, particularly cheaply, will also offer cheap quality foam. I have never seen a perfect and cheap cold foam myself…

Polyol should be in cold foam, but this is a costly substance. The more Polyol, the more elastic the foam becomes and the more support and comfort the cold foam will provide. Also, the Polyol ratio directly affects service life. In short, the amount of Polyol determines the quality but also most of the comfort. In addition to the Polyol ratio, the density (HR value) also indicates whether you are buying a good resilient cold foam (mattress). Still, the Polyol ratio is even more important.

HR value the same as SG value?

The HR value determines the foam’s weight and is completely comparable to the SG value (specific weight). This value has a bit of an effect on quality but more because a low HR value (below HR 30) makes the foam soft, soft and less resilient. The HR value, therefore, says nothing about the quality. If it says HR 50, it means that the cold foam weighs 50 kg per cubic meter. HR stands for High Resilience and 50 for 50 kg/m3. On various (colleague) websites, I read that the HR value indicates the quality. This is really absolutely not the case. The HR value indicates only the weight of the foam. The Polyol ratio and your supplier say much more about the cold foam’s quality than the HR value.

 

The importance of Polyol in cold foam

Polyol provides elasticity and resilience. Elasticity directly affects comfort because it ensures point elasticity. The more elastic the cold foam is, the easier it can follow the body’s contours and the more support it can provide. Besides, elasticity also offers comfort and ensures a longer service life.

Ingredients cold foam

The process of making cold foam and what substances you need for it is only interesting for a chemist or physicists (who could look at www.koudschuim.info). Polyol and MDI are, in any case, the most important ingredients. The polyol can be divided into; Conventional Polyol, Polymeric Polyol, Base Polyol, Modified Polyol for Cold cure. Besides, foaming Agents, MDI and dyes must be added. The MDI can be divided into; Olymeric MDI, Monomeric MDI, Prepolymeric MDI, Modified MDI for cold Cure. The proportions of the ingredients used by the foam manufacturers are secret. As a result, the different types of cold foam and their qualities are vastly different per manufacturer.

Rejected foam, what happens to that?

Usually, well-known foam factories such as Eupen always deliver the same quality and disapprove of mass-produced foams. The disapproved foams are then offered in shredded form for cushion etc. These excellent foam factories always work with a good Polyol ratio but are therefore always considerably more expensive. The price of a cold foam mattress is, therefore, almost always an indication of the quality. There are now (2020) a few German suppliers of cold foam mattresses on the Dutch market and these work with nasty cold foam. You can immediately see this in the price. But also well-known large chains usually work with cold foam that is not good quality. It’s a real shame because cold foam can offer so much comfort and so great lying down, but then it has to be excellent quality.

 

What affects cold foam comfort and longevity

What really creates the comfort of a cold foam mattress? It starts with the HR value and how good the quality of the cold foam is. After that, the thickness (height), the profiling (incisions for zones) and the tick play a major role. The thicker the cold foam mattress, the longer it lasts, and the more comfortable the mattress offers. In my opinion, a good cold foam mattress for an adult should be at least 20 cm thick (but preferably 25 cm thick). Only at 20 cm or more can you take a fairly smooth cold foam without risking being “through” over time. Lying “through” is called “bottoming out” in the mattress industry and is very bad for a correct posture and comfort.

The tack (the textile, the cover that surrounds the mattress) and any profiling in the foam also affect the comfort. It is always best if the tack is knitted instead of woven. A knitted tack stretches along with it, and therefore, the mattress can better follow the body’s contours. It is also advisable not to opt for a synthetic mattress calibration but a natural material (e.g. Tencel). Also, the tick must be washable (at least at 60 degrees because this kills dust mites).

 

Bad cold foam

Especially in the last few years, I see nasty cold foam passing by. Often this cold foam comes from China, so it is also dubious what is in the foam. There is no control over foam producers in China at all, so they can put in whatever they want. But now also from Germany, real bad cold foams are coming to the Netherlands. I think all this has to do with the crisis, among other things. After all, every euro has now been taken into account. I’m worried about this development. Soon, consumers may no longer have confidence in the cold foam product because negative stories about cold foam will be circulating.

Of course, these cold foam types are beautiful from a price point of view, say cheap. But exactly what’s in it isn’t clear. This is, of course, a bad development, and there are already known cases of people with tearful eyes, headaches and itching complaints after purchasing a new mattress. You can overcome this when purchasing a mattress by asking for certificates and asking which foam factory produced the foam. If this is not entirely clear, I would never buy it myself. Realize that you will spend one-third of your time on this product.

 

Medical quality cold foam mattresses

Medical quality cold foam is the best quality mattress available. It has tested all possible certifications such as LGA, Certipur, HygCen and Medisch.

Medically qualified cold foam has a guaranteed good ventilation capacity and offers absolutely even backpressure. This foam remains cool (even with 24-hour use in a hospital) and has a long service life. The foam is hygienic and can be cleaned at a high temperature. For hospitals, medically qualified cold foam must be autoclave-cleanable (car wash in a hospital where mattresses above 100 degrees are cleaned); this is not relevant for a consumer. Medically qualified cold foam is rarely offered to the private (consumers) but is usually delivered directly to hospitals.

 

Cold foam and hospitals

Pretty much every hospital uses cold foam mattresses. Why? Firstly, cold foam can handle large weight differences, and besides, it lasts a long time, with little chance of silage formation.

Cold foam mattresses are completely hypo-allergenic, and probably this is the main reason that cold foam mattresses are used in almost all hospitals nowadays.

 

How do you recognize a high-quality cold foam mattress?

High-quality cold foam mattresses can (usually) be recognized by the price. A perfect cold foam mattress is usually quite expensive but also really durable. With poor cold foam, the resilience, lying comfort and service life is significantly less than with a good quality cold foam. Poor or rejected cold foam often offers disproportionate backpressure, and prices can only be 50% below normal sales prices. The quality differences are feelable and measurable and directly affect comfort, posture (ergonomics), and service life.

 

How much does a good cold foam mattress cost?

A good cold foam mattress (HR 50 or more) in size 90 x 200 with a luxurious mattress calibration and a thickness of 20 cm should cost at least € 400-. But a truly top-quality cold foam mattress with a thickness of 25 cm made up of several layers of cold foam with a high HR 65 value and with a luxurious thick padded natural tack could cost between €800- and €1200.

 

What is the best cold foam mattress?

This is a tough question that I am regularly asked. Actually, there is no such thing as the best mattress and therefore not the best cold foam mattress. The best cold foam mattress is the cold foam mattress that suits you best. As indicated in this article, there are substantial quality differences, and there are several points you could pay attention to. The best cold foam mattress should have: a thickness of at least 25 cm, an HR value preferably above HR50, at least 7 zones and made up of 2 or 3 layers (for stability). It can help if the mattress also has ventilation ducts for extra ventilation. The mattress’s tack must be detachable and washable at least 60 degrees and preferably of natural material (e.g. Bamboo or Tencel). A mattress with which I have great experiences is the Comfort Premium Air cold foam mattress, but of course, there are many more for sale.

 

The lifespan of cold foam

The lifespan of a cold foam mattress depends heavily on the quality and the foam manufacturer. A perfect cold foam mattress with a good Polyol ratio has a lifespan of at least 10 years. Please note that you turn the mattress over regularly as this significantly extends the service life.

 

Where can you find a perfect cold foam mattress?

There are several suppliers for high-quality cold foam mattresses. For example, you can contact debeen Slaapadviseurs, Ruwette beddenspeciaalzaak and of course me(Royal Health Foam mattresses) because I also go completely for quality!

 

Disadvantages of cold foam

There are actually hardly any disadvantages of cold foam to mention for the use of mattresses. If I had to name a few, the weight could be one of them. Good cold foam is fairly thick and, therefore, quite heavy. Another major disadvantage is the quality difference. The consumer is more or less in the dark about whether it is a high-quality cold foam or not.

So people who prefer to be hot in bed should opt for a combination of cold foam and memory foam as this reduces the cooling effect of cold foam. Also, the price of a good cold foam is quite high, especially if you compare it to a polyether or Bonell springs mattress. However, the high price of cold foam is made up of extra comfort and a longer service life without creating silage.

 

Poor quality cold foam

A major disadvantage of cold foam is that the quality differences are so large. Is it a top-quality cold foam or a rejected cold foam? The problem is that it is difficult to see and also difficult to feel. If you don’t have any comparison material, it’s also difficult for me to judge, let alone for a layperson. The lesser cold foams offer less resilience and (even worse) offer irregular backpressure.

 

Advantages of cold foam

The advantages of cold foam, especially when it comes to mattresses, are numerous. Cold foam offers good ventilation, lasts a long time and offers a lot of resilience (and therefore, support). Although comfort is a subjective (personal) thing, you can safely say that cold foam offers many comforts. This is because it is very smooth and actually has everything for making mattresses. A cold foam mattress does not become clammy despite someone sweating heavily on it because cold foam quickly evaporates moisture and because it sinks easily through it. It is also temperature neutral and offers a huge amount of resilience (at a high HR value), which ensures excellent support.

The long service life is definitely also an advantage. For example, if you compare the lifespan of cold foam with Latex, the difference is huge. A good latex mattress will last on average about 6 to 8 years, while a good quality cold foam mattress can easily last 8 to 10 years. And finally, cold foam is also easily recyclable, which of course, benefits the environment.

 

Conclusion

A cold foam mattress is cool, very resilient, absorbs moisture well and does not get silage. It has a long service life.
