These toppers are made of quality memory foam, which conform to the body's shape, distributing weight evenly and reducing pressure points. The convoluted design of the foam topper features a series of hills and valleys that create a more breathable surface for improved airflow and temperature regulation. The addition of gel into the foam layer provides further temperature regulation by absorbing excess heat and dissipating it away from the body. The toppers come in various thicknesses, usually ranging from 2-4 inches, which can be selected based on individual preferences and needs. They are also available in various sizes, including twin, full, queen, and king, making them suitable for most bed sizes. They also offer additional benefits such as motion isolation and durability, making them a popular choice for people who suffer from body aches, discomfort, or who simply want to enhance their sleep quality.
