Abstract

A mattress includes a first spring unit having a first degree of firmness, a second spring unit having a second degree of firmness different from the first degree of firmness, and a transition zone that is disposed between the first and second spring units. A foam perimeter surrounds the first and second spring units and the transition zone. The transition zone has a first row of springs adjacent to the first spring unit and has a degree of firmness between the first and second degrees of firmness that is closer to the first degree of firmness than the second degree of firmness. The transition zone also has a second row of springs adjacent to the second spring unit and has a degree of firmness between the first and second degrees of firmness that is closer to the second degree of firmness than the first degree of firmness.
