Are foam mattresses healthy?

Yes, foam mattresses are the safest choice. Polyurethane foam itself is hypoallergenic. Foam is also a material that is not liked by dust mites and other allergens, as well as insects. This helps to maintain high hygiene in the bed. However, it is worth checking the type, density, and hardness of the foam in question.

Are there natural foams for mattresses?

No, every polyurethane foam is synthetic. Sometimes they contain a small amount of plant oils, which probably do not translate into more favorable properties. At the same time, there is no reason to be afraid of polyurethane foams. They are a completely safe and hypoallergenic material, currently the best for building mattresses.

How to determine the hardness of sleeping foam?

The hardness of sleeping foam must be based on a numerical value specified in kilopascals (kPa) or newtons (N). Every manufacturer of polyurethane foams marks them in the same way. First, there is a letter designation for traditional foam (T), high resilience foam (HR), or memory foam (V). Then, the first two digits indicate its density in kg/m3, and the next two indicate the hardness in kilopascals (kPa). Sometimes, the hardness is specified with three digits in newtons (N). The hardness scale used by sellers based on designations H1, H2, H3, or H4 is not standardized in any way, and there are no standards for it.

Is polyurethane foam flexible?

Flexibility and dynamics are the basic properties of high resilience foams (HR), which also have an open cell structure. Memory foam (V) is also very flexible but almost completely non-dynamic, depending on its temperature and parameters. Traditional foam (T), on the other hand, has very little flexibility, which is due to the closed cell structure of the foam. Therefore, it is always worth verifying the parameters of foams in the mattress.

What does an orthopedic pillow look like?

Most often, an orthopedic pillow looks like a wave or a bar of soap, which, according to the majority of manufacturers, is supposed to correspond to the curves of the spine. In reality, such a shape has little to do with the anatomy of the body. It can simply be easily cut from a foam block. A truly orthopedic pillow should be tailored to the physiological curves of the spine, so it should have special contours for the neck, as well as the shoulders and head. Only maintaining the ergonomics of the pillow's shape can make it truly orthopedic.
