  • Mattress having foam encasement and method of making the same
    Patent number: 7631381
    Abstract: A mattress core unit, such as an innerspring, is placed inside a foam envelope, which in turn is covered with fabric. The side and end rails of the envelope overlap the bottom panel, to provide good support for all edges of the mattress. The top panel of the envelope overlaps the side and end rails. To make a reversible mattress, an overlapping bottom foam panel is used. The method simplifies matress construction, reduces the number of required stock keeping units, and provides a comfortable, yet firm, feel at the edges of the mattress.

  • Method of making mattresses
    Patent number: 7484282
    Abstract: A pillow top mattress is made by first folding a mattress core border strip lengthwise to form at least one integral pillow top border, cutting diamond-shaped notches out of the folded edge, and sewing the free edges of the notches together to form mitered corners. The strip is cut to length, and after its ends are joined together to form a band, it is pulled over the mattress core. The border strip is then secured to the core material, and pillow top insulation is added before a pillow top panel is sewn to the free edge of the border strip.
