Memory foam was first developed by NASA to reduce the G-forces astronauts feel during liftoff and was later incorporated into contour memory foam pillows. The memory foam softens when heat comes into contact with it and moulds into your shape, giving even support to your body.
Later on, memory foam was used mainly in medical applications and hence the first memory foam available to consumers was quite expensive. Over the years they have come down in price giving everyone the chance to have a good night’s rest.
When the general population talk about memory foam pillows, they are talking about contour pillows. They are called this because the memory foam has been molded to a specific shape – usually thicker on the top and bottom and thinner in the middle of the pillow.
This unusual and special shape is designed to keep your spine properly aligned by allowing your head to rest in a neutral position. With this your head and neck will continue to have support throughout the night.
