There is not a perfect mattress that fits everyone. The best mattress is the one that offers you best comfort and a good price-performance ratio. Therefore the first question when buying a mattress is what are your sleeping habits, your requirements and what extras do you need. Be aware that the different technologies offer you different kinds of comfort and that there is a broad variety of qualities. Mattresses that look alike at first sight may be different.
PE
As polyether PU foam has a semi-closed cell structure and does not enhance comfort it is seldom used for the manufacture of mattresses. So-called polyether PU foam with its open cell structure is used in mattresses in the medium/low quality range. It is also commonly known ass “standard PU foam” or “polyether foam”.
High Resilient
High resilient foam, or shorter HR foam, is characterized by an irregular cell structure showing high flexibility and elasticity. HR foam is one of the most commonly used mattress core materials, especially in mattresses of the medium/medium and medium/high range. High resilient foam has anti-microbial properties, which offer additional protection to people suffering from allergies. It is also flame retardant. High resilient foam is recyclable and its production technology eliminates CFCs, methylene chloride and other blowing agents that can destroy the ozone and contribute to global warming.
Visco-Elastic
Visco-elastic or memory foam is made from polyurethane with additional chemicals that add to its viscosity level, thereby increasing the density of the foam and providing a cell structure different from other foams, which makes it less ‘springy’ and slower to recover.

Natural
Latex is a resin obtained by cutting the bark of a tree. About 99% of all natural rubber comes from the latex of the Hevea-brasilienis tree, commonly known the rubber tree. Narrow grooves are cut into the tree’s bark. The latex oozes out of the cut in the tree, goes through the spout and into the cup. Each tree gives about a teacupful of latex per day. The rubber tree is cultivated on plantations in South Asia, South America, Africa, Indonesia and Sri Lanka.
Synthetic
The synthetic rubber industry was developed due to lack of availability of natural rubber during World Wars I and II. Petrochemical synthetic latex is claimed to have the same properties as natural latex, and nowadays, most latex mattresses tend to be either made of synthetic latex or more typically a combination of synthetic and natural latex. The combination latex core is more resilient. Synthetic latex is cheaper and as such more cost effective for the production of mattresses.
Spring shape
There are several shapes of spring, and it may be a good idea for a consumer to try lying on the different
kinds to see which type suits best.
