Classical polyurethane foam mattresses: the most affordable models in this range, these mattresses are made of low density polyurethane foam (between 20 and 50 kg / m3). They generally provide medium to medium-strength firmness, making it suitable for those sleeping on one side or on the back. Many of the foam mattresses are made of at least two layers of material, sometimes compact, sometimes with a honeycomb internal structure, and may include special upper layers.
Among the advantages are lower weights, good resistance over time and hypoallergenic properties. But classic foam mattresses are slightly overheated, a particularly disturbing feature especially in the summer, and are also heavier.
It should also be noted that polyurethane mattresses can be divided into several categories. Those who have low weight or want a mattress for casual use can opt for lower density foam (20-35 kg / m3) and a lower price. For daily use or if the weight to be supported by the mattress is considerable (over 100 kg), mattresses with a higher density (35-50 kg / m3) will prove more comfortable and more resistant over time.

Mattress foam mattresses
A variety of the above, memory mattresses use foam with a high density that molds to the shape of the body. Normally comfortable, these mattresses tend to have a higher tendency to overheat the body, and sometimes they can definitely pull off if the body weight is high and their density too low. In addition, their firmness varies with temperature, a cold mattress being tougher than a heated one. For people who suffer from chronic fatigue and need softer mattresses, memory foam is probably the best choice. If you do not sleep alone, these mattresses also offer a very good localized deformation that will not disturb your partner.
Foam mattresses are mostly made of a support layer (or more) of polyurethane foam and a top layer of memory foam (foam with memory). In order to be able to feel the benefits of memory foam, our advice is to choose mattresses with a stronger coat (high density and minimum thickness of 12-15 cm) and a layer of memory foam of at least 7 cm (density over 80 kg / m3, preferably, otherwise it will melt in time). Ample and helpful information in choosing the choice of these types of mattresses are available here.
