Memory foam was developed by NASA in the 1970's, but it was made famous in the consumer market as topper pads. Later on in the 1990's, the memory foam mattress was established. From then till today, it has occupied a very prominent space in the mattress industry.

Sleeping on a memory foam mattress is considered good for people with back problems, arthritis, bone and joint problems. Memory foam mattresses are available in a number of sizes such as single, double, queen, king, California queen, California king and super king sizes. Some double memory foam mattresses have both a softer and harder side to meet the requirements of sleeping partners. Mostly, the density of a memory foam mattress is about five inches.

It is not necessary that all the mattresses available in the market are sensitive towards temperature. However, this feature of the mattress must not be underestimated as it is very important. This is the feature that makes a memory foam mattress unique, and absolutely comfortable.
