  • Patent number: 6292965
    Abstract: A mattress with two bands running across its faces to increase firmness and body weight distribution. These bands are composed of panels of a highly resilient material fastened to panels of non-resilient material. The resilient panels are positioned where the greatest load concentrations are likely to be when the mattress is in use. The resilient panels are oriented to stretch in a direction parallel to the major dimension of the band and, as they are stretched, increase in tension in proportion to the load. The greater the load, the greater the tension on the resilient panels and the firmer the mattress becomes in response to the load.
