What is Memory Foam?
Memory foam consists mainly of polyurethane as well as additional chemicals increasing its viscosity and density. It is often referred to as “viscoelastic” polyurethane foam, or low-resilience polyurethane foam (LRPu). Higher-density foam softens in reaction to body heat, allowing it to mold to a warm body in a few minutes. Newer foams may recover more quickly to their original shape.
Why choose a memory foam product?
A memory foam mattress is usually denser than other foam mattresses, making it both more supportive and heavier. Memory foam mattresses are often sold for higher prices than traditional mattresses.
The property of firmness (hard to soft) of memory foam is used in determining comfort. Firmness is measured by a foam’s indentation force deflection (IFD) rating. However, it is not a complete measurement of a “soft” or “firm” feel. A foam of higher IFD but lower density can feel soft when compressed.
Pillows are key to a good night’s sleep, and foam pillows are very popular.
Sleeping on a good pillow can be the difference between waking up with a sore neck or back. Furthermore they can leave you waking up refreshed and rejuvenated.
Of course, there are plenty of pillows to choose from. We’ve already highlighted the best pillows overall, but these days, many people prefer to go for a foam pillow over any other kind of pillow — and for good reason. foam pillows are better at contouring to your specific needs and keeping your spine aligned, which is much better for your neck in the long run.
