Memory Foam provides for a great sleep experience by moulding itself to your body. Through this action it relieves key pressure points along your entire body allowing for a much more comfortable sleep.
Sleeping on a natural curve is the best position for your spine alignment and lumbar support. It consists primarily of polyurethane foam and an additional chemical mixture to make it “viscoelastic” or a low-resilience polyfoam. This type of foam has an open cell structure which allows its matrix of air bubbles to move and recover to the original shape it was cast into more quickly.
This property is also what allows it to mould to a warm-body in just a few minutes, giving its great support properties for mattresses and pillows.
