The maximum weight for which one bed of the mattress is designed is, in fact, the maximum weight of a person who can regularly sleep on a mattress for a long period of time without the risk of "overloading" and spoiling the product. Of course, this parameter cannot be exceeded; however, when purchasing a mattress, you should also make sure that the selected model has a certain weight reserve — at least 10 kg. This is due not only to the fact that the mattress can be used by different people (and the weight of permanent owners can also change), but also to the uneven load that occurs during use. The fact is that manufacturers can specify this parameter per sleeper, i.e. practically immobile person. In fact, the matter is not limited only to sleep — as a result, the mattress may experience a load greater than the calculated one, even in cases where the weight of the person on it does not exceed the claimed characteristics.
Overall height (thickness) of the mattress.
This parameter is selected by the manufacturer, taking into account the general purpose and design features of the product, so in most cases it is not fundamental when choosing. We only note that traditional type mattresses have a thickness of
10 – 15 cm to
30 cm or more. And products with a thickness of less than 10 cm belong to the category of so-called
futons, or toppers. Most often, such models are not used separately, but as additional overlays on another sleeping surface. For example, you can add a topper to an existing classic mattress — if it is not soft or hard enough, or if its properties have deteriorated due to wear — or lay the topper on a sofa, making the sleeping place on it more comfortable. Due to their thinness, futons are relatively inexpensive, and buying such a product is often more profitable than replacing an existing mattress.
