Mattresses with different side stiffness

Different firmness of sides

— mattresses that have different firmness characteristics on different sides, such as soft/medium or soft/hard. One of the options for using such models is sleeping places for people with chronic back problems: during periods of exacerbation, it is sometimes recommended to sleep on a harder surface. But even in the absence of health problems, such mattresses can be useful – for example, if you would like to periodically change the sleeping conditions, or if the same bed sometimes has to be used by different people who differ in weight and/or preferences. Also note that products of different firmness partly provide the “winter/summer” effect, even if this function is not directly stated in the specifications: it is believed that the sleeping surface for the cold season should be softer than for the warm one.

In any case, by purchasing such a mattress, in one product you will actually receive two sleeping places with different characteristics – which is often more convenient (and definitely cheaper) than purchasing two separate mattresses.
