Viscoelastic, also called viscoelastic mattresses, mattresses are manufactured with foam mattresses memory foam, also known as memory foam, a polyurethane foam which adapts to the shape of the body and dissipates the pressure, so it is used in mattresses, pillows, cushions, or helmets. Viscoelastic mattresses provide a healthy and pleasurable, rest on his firmness, adaptability to body, elimination of pressure points and sensation of weightlessness. Features foam viscoelastic is a synthetic material developed by NASA in the 1960s within the space program to decrease the pressure supported by the body on takeoff, having been applied to domestic uses, such as viscoelastic mattresses, since early 1990s. It adapts to the shape of the body, dissipating the pressure so uniform, returning to its original shape once the pressure is removed. Let’s look at the main features of the viscoelastic mattresses: Adaptable by the weight and body heat, provides a pressure stable and uniform throughout the body with sensation of weightlessness. Given that are ergonomically adapted to the body, reducing pressure points, viscoelastic mattresses allow keep longer working position avoiding postural changes during sleep, favouring relaxation. Thanks to the open cell structure, viscoelastic mattresses have aeration and ventilation, avoiding the accumulation of heat and humidity.
Heatproof material, do not transmit heat or cold. Viscoelastic mattresses just need maintenance, simply rotate head to feet, without flipping them since they only have a suitable sleeping face. Viscoelastic mattresses can go on all types of mattresses, bedsteads or upholstered bases. You can place any type of protective cover. Viscoelastic mattresses parts have two layers: padding: is the top layer, upon which rests the body, is the layer viscoelastic. Core: is the bottom layer, which is in charge of firm, consists of foams of high density (HR, Eliocel). Types of foam viscoelastic in viscoelastic mattresses are used different types of foam visco-elastic: Visco-Elastic foam: is made by depositing the viscoelastic in an open area so that when you add the reagent grows without limitation. Then cut the block to the desired extent.
Cell or pore is larger than that in molding, so the airflow through the viscoelastic is faster and reduces the memory foam sensation. Moulded viscoelastic: manufactured by introducing the viscoelastic along with the reagent material in a closed mould, so to find stops does not increase freely size. Therefore the pore is smaller and the airflow is slower, achieving greater sensation memory foam. Natural viscoelastic: in this material are replaced components from petroleum by others of vegetal origin, thus obtaining a more natural mattress hygienic, ecological and healthy.
