If you are about to buy a foam mattress, know that density is an important factor in choosing. Combined with other criteria (ventilation of the mattress, durability…), it can offer you optimal comfort. Indeed, the density determines the degree of firmness of your mattress and gives you indications as to its durability. In detail, density indicates how many kilograms of gross mass of a substance are contained in one m3 of foam. Overall, the higher the density, the more qualitative the mattress. It also affects the life expectancy of the mattress, because if the density is high, the foam is heavier and so is the elasticity of the mattress. Here is all thatyou need to know about the density of foam mattresses as well as some advice on choosing the model best suited to your needs and your body type.

What is the density of a mattress?
Before helping you choose the density of your future mattress, you must first define this concept. This is the amount of components present in the mattress. The density of a mattress is measured in kg / m3. It therefore indicates the weight of raw material contained in a cubic meter of foam. For example, a mattress of 40 kg / m3 means that out of 1 m3, there are 40 kg of foam. While consumers tend to focus on thickness, fill, dimensions, price and technologies used when choosing a mattress, density matters just as much. Indeed, this criterion influences the comfort of the mattress and its lifespan. The greater the density of the components, the better the body is maintained. Likewise, the higher the density, the longer the mattress is expected to last.
What density to choose for a foam mattress?
There is no ideal density for a foam mattress, simply because there are different types of foam (cold foam, viscoelastic memory foam, and polyurethane foam). To have flexible support, it is advisable to choose a mattress with a density between 50 and 70 kg / m3. If you prefer to enjoy a firm or even very firm support, you should respectively opt for mattress densities between 70 and 85 kg / m3, or more than 85 kg / m3. This is called a high density foam mattress. Besides that, the selection of the right mattress density is made according to the weight of the users. People under 70 kg can turn to mattresses with a density of 30 to 45 kg / m3. In contrast,people between 80 and 95 kg have every interest in opting for a mattress density between 65 and 75 kg / m3. As for people over 100 kg, who require perfect maintenance of their body to preserve their health, they are invited to opt for more high-end mattresses, with a density greater than 75 kg / m3. Note that today's mattresses are generally made of several layers of foam. It is therefore complex to assess their overall density. It is necessary to take into consideration the density of each layer in order to get an idea of the firmness of the mattress as a whole.with a density greater than 75 kg / m3.
