Known Allergies Related to Foam

October 22, 2011

Even in its greatest form, I cannot say that a foam mattress is a perfect product, for this is an imperfect world. Sure, polyfoam mattresses provide excellent neck and back support. And sure, they are comfortable and affordable, but it’s good to remain conscious and know that there will always be some things that you have to deal with for your own good.

In this case, they are allergies related to foam mattresses. Here at Uratex, we care for your health. That’s why we take the extra mile to ensure you that you’re always comfortable and rested through a good night’s sleep. These are all necessary for the well-being of your health. But, and this is very RARE, if you are one of a small number of people who are allergic to polyurethane products, such as polyfoam and memory foam, this article will serve as somewhat of a guide to known allergies related to foam. Now most of these are general, and this is not a list of medical terms for your reference. Rather, this is to help you know (if you don’t know yet) whether you are allergic to foam. I’ll also help you do something about it.

The very common heat rash.Foam-Related Allergies

I’ll remind you that polyfoam mattresses are cool to the skin because of the bubbles of air packets which allow air to flow. This makes the heat rash more common with people who own memory foam. Memory foam is a little denser than the normal polyfoam; the compactness of the material absorbs your body heat but very slowly releases it – slower than the rate by which your body deposits heat.

This kind of “stuck heat”, along with your skin’s contact with the material for extended periods of time (i.e. as you sleep), will cause a heat rash. Honestly, plenty of things can give you heat rashes. Clothes, cushioned seats, and even your own skin! Have you ever had rashes at the folds behind your knee? That’s also a heat rash. Therefore, this type of “allergy” can also be considered as an indirect reaction. If you are having trouble with the heat rashes caused by your memory foam bed, try putting a mattress topper made of a different material. In that way, you won’t be bothered by the task of having to look for a new mattess. It’s more practical, you know.

Direct allergic reactions.

Some people are simply allergic to one or most of the chemical ingredients used to make foam mattresses. The chemical found in beds that is most likely to set off an allergic reaction is called isocyanate. This largely causes asthma, but it can sometimes also cause headaches and nausea. Reactions to this chemical vary upon the amount of isocyanate used and the person’s immune system. Remember that in foam mattresses, it’s just one of the ingredients, and therefore the reaction will not be as harmful. But again, there are those people with ultra-sensitive immune systems that violently react to even just trace amounts of allergens. This may trigger eye, nose, and throat irritations.


This can be caused by being in contact with the materials of the polyurethane itself. Dermatitis is another term for rashes, but an allergic manifestation of dermatitis is something serious. No one wants to have itchy, annoying rashes. There is really one obvious way to deal with dermatitis caused by polyfoam beds, and that is to simply avoid contact with the foam itself. Maybe a thick bed sheet would help.

Uratex foam mattresses are great and comfortable, but if you are unfortunately allergic to foam mattress, a mattress topper is the best solution. But remember, though your immune system may not allow you to sleep on a foam mattress there can always be a way. Also keep in mind that nothing should stop you from having a good night’s rest. Not even your allergies.
