Polyurethane Foam Mattress
What is a polyurethane foam mattress?
Polyurethane foam mattress: Definition PUR foam
A polyurethane foam mattress consists of PUR foam and is also referred to as a PU mattress or PUR foam mattress. It is a comfort foam mattress made of polyurethane, which is abbreviated as PUR or PU. The term PUR foam mattress is mostly used colloquially and refers only to the DIN abbreviation (PUR). Polyurethane is used in various applications due to its material properties, so it is used, for example, as polyurethane foam mattress materials. The PUR foam made from polyurethane (polyurethane foam) is foamed both as a soft and firm material. In the production of mattresses, such as a polyurethane foam mattress, the advantages of the soft foam are needed, as it is more open-pored and has several hardness levels. For the production of a foam mattress, the PUR foam is foamed from polyurethane foam. The density of a polyurethane foam mattress is, for example, lower than that of a cold foam mattress.
Polyurethane foam mattress: Material polyurethane
(PUR foam mattress)
Polyurethane is a plastic that is created through a chemical reaction. As early as the mid-1950s, polyester foam was first produced as a material. From then on, polyurethane gained a high demand and is used not only for mattresses but also in construction and the furniture industry. Foam mattresses made of PUR foam are, however, the main area for the use of polyurethane. PUR foam mattresses or comfort foam mattresses are manufactured to be particularly breathable and air-permeable.
Polyurethane foam mattresses: density
Due to the low density and low compression hardness, foam mattresses, such as the polyurethane foam mattress, are lightweight and suitable for easy transport. Unlike other mattresses, such as latex mattresses, cold foam mattresses or gel mattresses, they weigh fewer kilograms and have advantages in the open-pore cell structure. Density and compression hardness are lower, making these mattresses suitable for people in bed who have less body weight in kilograms. People with low body weight include children who sleep on children's mattresses or a person, e.g., a baby on a baby mattress. The quality of a foam mattress increases when extra zones are milled in, such as in a cold foam mattress made of cold foam with 5-zone or 7-zone structure. These lying zones in the mattress promote a better body adaptation and body weight adjustment.
Polyurethane foam mattress: Difference between cold foam mattresses made of cold foam and comfort foam mattresses
Comfort foam mattresses or PUR foam mattresses have many advantages due to their properties. The open-pore structure of the foamed material allows the foam mattress to ventilate and breathe well. A PUR foam mattress made of polyurethane foam is foamed with heat. However, the point elasticity is by no means as good as that of a cold foam mattress , e.g., for box spring beds. However, mattresses made of polyurethane are very well suited for all slatted frames and are easy to turn due to their light weight . Unlike a cold foam mattress, which is foamed with cold and has a different cell structure. The open-pore structure is created by additionally crushing the mattress. Comfort foam mattresses are in the price segment below cold foam mattresses made of cold foam, as they have a lower weight and the cell structure is different. Furthermore, cold foam mattresses made of cold foam offer various sleep zones for the human body that can be comfortably felt while sleeping. The sleep zones are designed for the body to sink in more at the more heavily stressed areas (head, shoulders, pelvis). The weight and compression hardness are higher in cold foam mattresses made of cold foam compared to a polyurethane foam mattress made of PUR foam. Combined with the appropriate bedding and slatted frames, it becomes much cozier in bed.
Lying zones of the comfort foam mattresses
Comfort foam mattresses are available, for example, in the following hardness grades, which can be chosen according to the lying feeling:
- Hardness grade H1
- Hardness grade H2
- Hardness grade H3
- Hardness grade H4
Polyurethane foam mattress: Polyurethane foam as a reversible foam material
All foams that are deformable are considered PU foam. Foam material is foamed here using carbon dioxide, which is harmless to the environment. Depending on how high-quality a PUR foam material is, this is measured by the compression hardness and the density. The difference is therefore quickly noticeable when purchasing such a product, whether it is a high-quality mattress made of polyurethane foam or not. A good density for foam should be over 40 kg/m³. Compression hardness indicates how high the strength measure of the mattress is when sleeping. A comfort foam mattress made of polyurethane foam usually has a lower compression hardness than, for example, latex mattresses or visco mattresses. In mattress production, there is a distinction between products made from standard foam, such as comfort foam mattresses made from comfort foam or molded foam mattresses. The so-called second category includes cold foam mattresses, which are made from cold foam.
Polyurethane foam mattress: Cold foam mattresses made of cold foam
In the production of cold foams, no blowing agent is needed, unlike with standard foam. Cold foams are of higher quality compared to normal standard foams, as they have better material. Thus, people who sweat faster and lose water need foams that have high open porosity. The open cell structure supports this property. Latex mattresses are also suitable for this. The elasticity of cold foam mattresses is very good and is also suitable for allergy sufferers. For allergy sufferers who have, for example, a house dust mite allergy, foam mattresses are very suitable, as these mattresses do not provide a breeding ground for mites. They allow moisture in the form of water (night sweating) to evaporate and ensure a fresh room climate.
