Memory foam mattresses are designed to provide support and comfort by conforming to the shape of the body. Made from viscoelastic foam, they respond to heat and pressure, allowing the mattress to mold to the sleeper's contours. This feature helps to distribute body weight evenly, reducing pressure points and promoting better sleep. These mattresses are popular for their ability to absorb motion, making them a good choice for couples. When one person moves, the other is less likely to feel the disturbance. Additionally, memory foam is often hypoallergenic, making it suitable for those with allergies or sensitivities.
