Things To Know About Buying A Memory Foam Mattress In

Home-Appliances Memory foam is polyurethane with additional chemicals increasing its viscosity and density. It is often referred to as visco-elastic polyurethane foam. In some formulations, it is firmer when cooler. Higher density memory foam reacts to body heat, allowing it to mould to a warm human body in a few minutes. A lower density memory foam is pressure-sensitive and moulds quickly to the shape of the body. Memory foam was initially too expensive for widespread use,but in recent years it has be.e cheaper. Its most .mon domestic uses are mattresses, pillows, and mattress toppers. It has medical uses, such as wheelchair seat cushions, hospital bed pillows and padding for persons suffering long-term pain or postural problems; for example, a memory foam cervical pillow may alleviate chronic neck pain. Its heat-retaining properties may help some pain sufferers who find the added warmth helps to decrease the pain. Memory foam has an open cell structure that reacts to body heat and weight by ‘moulding’ to your body, helping relieve pressure points, preventing pressure sores, etc. Most memory foam has the same basic chemical .position, however the density and layer thickness of the foam means different mattresses feel very different. A high density mattress will mean it returns to position more slowly and will be firmer; a lower density will feel more like a normal foam mattress. The amount of memory foam also has an effect on the capabilities of the mattress or topper. Anything less than 2 inches will not have much of an effect, whereas a 6 inch block would be too soft and dense to sleep on .fortably. Therefore pocket sprung mattresses with a memory foam pillow top are probably the best! Each mattress, therefore, is a .bination of its height, density, and type, each of which will have different properties. With memory foam mattresses, Mildew and house dust mites may not occur as frequently so asthma attacks may be less frequent and severe. Memory foam, like other polyurethane products, can be .bustible. Irish Laws have been enacted in the Ireland to require all bedding, including memory foam items, be resistant to ignition from an open flame such as a candle or cigarette lighter.
