What is Visco Foam
Visco Foam was originally developed by NASA to decrease the pressure caused by the extreme g-force during take-off of the space shuttles. It was never used in the space program but has been adopted in many medical fields as well as retail mattress manufacturers to elevate pressure points while sleeping. Visco foam was initially too expensive for the general public, but in recent years it has become less expensive to produce and is now widely available in almost every price.
The most common used for visco foam is in mattresses, pillows, and mattress toppers. Its heat-retaining properties may help some pain sufferers who find the added warmth helps to decrease pain. A visco foam mattress tends to be denser than ordinary foam mattresses. This denser foam makes it more supportive but also quite a bit heavier. Mattresses with visco foam usually sell for more money than traditional mattresses but may last longer due to their resistance dust mites.
Visco foam is made from polyurethane with additional chemicals that increases its density and viscosity level. The foam is often referred to as visco-elastic foam. Depending on its density, the foam is typically firmer in cool temperatures and softer in warm. Due to the chemicals added to the foam, some new visco foams give off a distinct chemical odor, but will decrease with airing. Some people remain sensitive to it. Resistance to dust mites and mildew in the visco foam can be an important point for someone with asthma and allergies.
