Memory Foam is a type of polyurethane foam that is known for its ability to conform to the shape of the body. It was originally developed by NASA in the 1960s to improve the safety of aircraft seats. This material responds to heat and pressure, allowing it to mold to the contours of a person’s body, providing support and comfort. Memory foam is commonly used in mattresses, pillows, and cushions. Its unique properties help to distribute body weight evenly, reducing pressure points and promoting better sleep. Additionally, it is often hypoallergenic and resistant to dust mites, making it a popular choice for those with allergies.
