This type of mattress is constructed from Posturepedic springs. This means that the springs are connected in rows via a coil, and can move independently of each other, resulting in a mattress that sculpts itself to your body, providing excellent support. This mattress differs greatly from the traditional open coil mattress as these springs are not as supportive. The Posturepedic mattress is also recommended for those who are restless sleepers as the mattress helps you to maintain a comfortable sleeping position. The Posturepedic is Sealy's most popular mattress.
