The Memory foam mattress is a compromise to both firm and soft mattresses. It is apt for all. The Memory Foam mattress is available in lots of sizes like, Twin, Twin XL for adjustable beds, Full, Full XL, Queen, King and California King.

The Memory Foam has shown excellent characteristics in responding to changes in temperature and its capacity to reduce pressure by spreading the weight evenly over a larger surface area. Thus the memory foam used in a mattress has enabled to solve many problems like arthritis, bone and joint problems, etc. The visco-elastic nature of Memory Foam mattress helps to disperse accumulated pressure points away from the vertebrae.

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 was originally developed in 1966 under a contract by NASA’s Ames Research Centre as a way to improve the safety of aircraft cushions. Ames scientist Chiharu Kubokawa and Charles A. Yost of the Stencel Aero Engineering Corporation were major contributors to this project. Yost named the temperature-sensitive memory foam ‘temper foam’.

Memory foam mattresses have several orthopaedic and other health benefits. Though this product was initially developed for astronauts to support and reduce the pressure on their bodies during take-off and landing, memory foam could be considered one of the biggest assets to the bedding, orthopaedic and healthcare markets. Initially the benefits of memory foam mattresses were limited to the field of medicine. Patients suffering from bed sores or severe burns showed great improvement and relief if they used the mattresses.Even today all over the world memory foam is used in hospitals for the prevention of pressure sores. The foam moulds itself according to the shape of the body and enables the body support to be optimized. In this way the body is not subjected to any pressure points. In fact it even reduces the need to toss and turn at night. Most people who have a restless and disturbed sleep and are tossing and turning at night are mainly suffering from the creation of pressure points.

How memory foam mattress toppers and mattresses works to release your back ache is worth considering. This visco elastic foam is a revolutionary sleeping technology that distributes body weight evenly and relieves pressure points that helps you sleep better at night with no back aches in the mornings, reducing pressure points up to 80% and giving you a sound sleep overall. Memory foam also has the capability to react with human body temperature and adjust accordingly.

Spring mattresses rely on springs that force upwards pressure against the body. This causes the body stress and results in a restless night. Memory foam works in a completely different way; it absorbs the weight of the body, whatever shape or size, and forms a cradle that moulds to the body contours without pressure or force.
