The mattress is a soft, thick bedding for lying, as well as a part of a bed or a sofa with a wooden frame and inside springs that can be removed . There are mattresses filled with air or water.
Types of modern orthopedic mattresses
Modern orthopedic mattresses can be of two types: spring and springless.
Structure of a springless mattress
Springless olee sleep ventilated mattress is formed by layers of monolith of latex or polyurethane foam, and also other fillers (coconut plate, cotton fabric, wool, etc.). To create rigid models of springless mattresses, a combination of latex and coconut plates is used, more subtle than monolithic block.
Spring mattress structure
Spring block, fillers, auxiliary layer, cover — these are the main components of such a mattress. Spring blocks, in turn, are divided into dependent and independent.
Dependent spring block
The dependent spring block (block-dependent weave, Bonnel, LFK) is so named because it uses spiral-shaped springs that are joined together. Influence on one spring causes movement of others. Mattresses with dependent springs appeared more than 150 years ago. Modern manufacturers who use the dependent spring blocks presenting them today, combined with high-quality materials of layers and covers.
Mattresses in dependent spring blocks combine traditions of comfort with an affordable price.
Independent spring block
Independent spring unit (pocket spring unit, independent springs, Pocket Springs, TFK, Multipocket, Vernestet, Interactive and others) are the result of more recent technological developments. The springs that make up such a block are not interconnected and operate autonomously, providing maximum convenience. Pressing on one spring does not affect others. Each spring is placed in a separate cover, and the covers are interconnected. The larger the number of springs per unit area, the higher the orthopedic effect of the mattress.
Fillers of mattresses
The main function of the mattress filler is to distribute the load and to provide a mattress of greater or less rigidity / softness. There is a large variety of types of fillers, manufacturers constantly experiment with materials and their processing. All fillers can be divided into two types: natural and artificial. The latter can be of two types: created from natural raw materials and specially processed, as well as completely synthetic. Special treatment of natural materials helps to emphasize and improve some of their properties. Both natural and artificial materials have several advantages and specific properties. Often in modern orthopedic mattresses, natural and artificial fillers are used in combination with each other. The choice of the filler and its combinations depends on the rigidity of the mattress, as well as its hypoallergenic properties.
- Coconut coir is a natural material with a high degree of rigidity.
- Natural latex (juve gvei) is a hypoallergenic filler that can withstand a significant weight, durable, but does not moisture.
- Horse hair — an environmental material of moderate rigidity, but can cause allergies.
- Seaweed is a hypoallergenic natural material with an antistress effect of moderate stiffness.
- Artificial latex belongs to materials of high rigidity and has excellent moisture exchange.
- Polyurethane foam is a budget option, a high level of rigidity.
