What is Memory Foam?
Memory foam is made from polyurethane with additional chemicals that increase its viscosity level, thereby increasing its density. It is often referred to as visco-elastic polyurethane foam. Depending on the chemicals used and its overall density, it is firmer in cool temperatures and softer when warm. Higher density memory foam reacts to body heat which allows it to mould itself to the shape of a warm body within a few minutes. A lower density memory foam is pressure-sensitive and will mould more quickly to the shape of the body. The example often used to demonstrate its properties is that a hand pressed into the foam and then removed will leave a clear impression in the foam.
Memory foam behaves very differently to furniture foam. It reacts to bodyheat by getting softer. These ‘heat-sensitive’ characteristics of the mattress and toppers,make them ‘moulds’ to the contours of your body offering unsurpassed levels of support and comfort to give you what is proven to be one of the best sleep surfaces around.whilst ensuring your spinal column is aligned correctly.
By cradling you in this way memory foam distribute weight and surface pressure evenly, For this reason memory foam has been used in Hospital applications for years on burns units and prolonged stay patients being bed-bound after a paralyzing stroke who used to lie in bed on hard or very firm mattresses for long periods of time without regularly moving. The pressure over some of their bony regions decreased or stopped the blood flow to the region causing horrific pressure sores and/or gangrene. Memory foam mattresses helped hugely to decrease such events.
Memory foam mattresses and toppers are so effective at relieving pressure and dispersing your body’s weight over a wider area they have been both clinically and medically proven to reduce tossing and turning through the night by up to 85%.
