A memory foam pillow is designed to provide support and comfort by conforming to the shape of your head and neck. Made from viscoelastic foam, it responds to body heat and pressure, allowing it to mold to your unique contours. This helps to alleviate pressure points and can improve sleep quality. These pillows are often recommended for people with neck or back pain, as they promote proper spinal alignment. Available in various shapes and sizes, memory foam pillows can cater to different sleeping positions, whether you sleep on your back, side, or stomach.
