In 10 Minutes, I'll Give You the Truth about Mattress


The degree of hardness of a mattress is not a fixed standard size. The manufacturers of mattresses specify the designation for the degree of hardness of the mattresses themselves. The most common are the degrees of hardness 1 to 4. Also H1 to H5, F1 to F5 or designations such as "soft", "extra solid" and "medium solid" are not uncommon. However, across all manufacturer differences, the following applies: The mattress hardness grade H1 (or F1 or "soft") stands for the softest mattress core of the respective manufacturer. Perfect for people who like to lie soft, one would think. But the opposite can be the case.

Who should avoid mattresses grade 1

Grade 1 mattresses allow a deep sinking of the body and can therefore be very uncomfortable. With a body weight of 80 or even 100 kilograms, the sleeper practically sinks to the slatted frame. This significantly affects the comfort of lying. In addition, the spine is not properly supported when sleeping. Especially with side-sleepers that makes an unpleasant impression. As a result, the spine hangs unhealthily. The body weight also rests on shoulders and pelvic bones. However, ideally it should spread evenly over the bed. Mattresses grade 1 are therefore recommended especially for a body weight of less than 60 kilograms, heavier people need a higher degree of hardness. "Soft" does not always mean "comfortable". You have to find the thebest-mattressthen.

How do the different degrees of hardness come about?

As an alternative to the term "hardness" often "strength" is used. The strength of a mattress arises depending on the mattress in different ways. In cold foam - latex - or viscos mattress that is density a critical size. It is determined how much a cubic meter of the core material used weighs. Very coarse-pored foam with lots of trapped air is much lighter and softer than more compact foam. In this one cubic centimeter contains significantly more material and less air. Here, the body weight is distributed to more supporting structures, whereby the increased strength is achieved.

An exception is foam mattresses such as cold foam mattresses. Here is not the volume weight, but the compression hardness relevant for the degree of hardness. Not the density, but the stiffness of the foam structure influences in this case hardness and lying feeling. So there are cold foam mattresses with low density, which can still have a high degree of hardness.

The degree of hardness in latex and pocket spring mattresses

Latex and natural latex mattresses are also occasionally reinforced with layers of firmer materials in the load-bearing zones. In this way, softer mattresses, especially in the shoulder and hip area more strength!

The situation is different with spring core and pocket spring mattresses. Here it is the springs inside the mattress that make up the carrying capacity. Their thickness and number determine the degree of hardness: mattresses grade 1 have springs of about 2 mm thick wire. The degree of hardness H2 would correspond to 2.2 millimeters of wire, H3 2.4 millimeters. In addition to the wire size and the number of springs also determines the number of turns per spring about their strength.

In case of doubt, only test beds and consultation help to find out if a mattress is suitable for a particular sleeper. Hardness and body weight alone are not enough in deciding for or against a mattress enough.

Why the height is important

For choosing the right degree of hardness, it makes a noticeable difference, for example, if 80 kilograms of body weight come to a body length of 160 centimeters or 190 centimeters. The weight of comparatively small sleepers is distributed over a much smaller support surface and thus to less load-bearing elements. A small but heavy person sinks deeper into the same mattress than a tall person of the same weight. It requires a higher degree of hardness for optimal body support.

What role does the slatted frame play in mattress hardness?

The feeling of lying ultimately results from the combination of mattress and slatted frame. Modern, high-quality slatted frames offer the possibility to regulate the hardness of individual bars via plastic sliders. They allow an individual adaptation. Here a consultation in the specialty store with regard to the zones to be adjusted further helps.
