  • Patent number: 6223370
    Abstract: A mattress having an anti-roll off feature is disclosed. The mattress has an innerspring unit having an array of coiled compression springs separating opposed parallel surfaces, wherein the surfaces are covered by a webbing made of a nonwoven polypropylene, and wherein the outer periphery of the webbing has horizontally disposed rigid foam planks wrapped and held in place by the webbing. The foam planks are formed from polyethylene foam. Additionally, vertically disposed rigid polyethylene foam planks with cross members are situated within the innerspring unit between the compressions springs at the periphery of the innerspring unit. The foam planks with cross members provide the support needed to achieve the anti-roll off feature. In an alternative embodiment, rigid polyethylene foam cylinders are placed within the rows of compression springs at the periphery of the innerspring unit to provide support at those locations.
