👉 Mattress fluid, also known as memory foam or innerspring mattress foam, is a specialized material designed to enhance comfort and support in mattresses. Composed of polyurethane and other polymers, it conforms to the body's shape, distributing weight evenly and reducing pressure points. This fluid continuously adjusts to the sleeper's movements, providing a snug fit that adapts over time as the mattress compresses and relaxes. It also helps to maintain proper spinal alignment, offering both support and comfort, while its moisture-wicking properties keep the mattress dry and reduce odors.
