Abstract
A side rail assembly and a mattress assembly including the side rail assembly about at least a portion of a perimeter of the mattress assembly. The side rail assembly includes a laminate structure including one or more foam layers and one or more fiber layers in a stacked arrangement. The fiber layer can be a non-woven layer.
Claims20
A mattress assembly, comprising:
- an inner core having opposing major surfaces defining a height therebetween;
- and
- a side rail assembly disposed about at least a portion of a perimeter of the inner core for supporting an edge thereof, wherein the side rail assembly comprises a laminate structure consisting of one or more foam layers and one or more fiber layers in a vertically stacked arrangement such that the one or more foam layers and the one or more fiber layers overlay one another, the vertical stacking being along the height of the inner core,
- wherein the one or more foam layers have a hardness property of an indention load/force deflection (ILD/IFD) of about 35 pounds-force to about 100 pounds-force and a density of about 1 pound per cubic foot to about 3 pounds per cubic foot, and
- wherein the one or more fiber layers have a hardness property of about 10 pounds-force to about 60 pounds-force in a machine direction at 25% and a density of about 0.5 pounds per cubic foot to about 10 pounds per cubic foot.
A side rail assembly configured for supporting an edge of an inner core of a mattress, the inner core having opposing major surfaces defining a height therebetween, the side rail assembly comprising:
- a laminate structure consisting of one or more foam layers and one or more fiber layers in a vertically stacked arrangement such that the one or more foam layers and the one or more fiber layers overlay one another, the vertical stacking configured to be along the height of the inner core,
- wherein the one or more foam layers have a hardness property of an indention load/force deflection (ILD/IFD) of about 35 pounds-force to about 100 pounds-force and a density of about 1 pound per cubic foot to about 3 pounds per cubic foot, and
- wherein the one or more fiber layers have a hardness property of about 10 pounds-force to about 60 pounds-force in a machine direction at 25% and a density of about 0.5 pounds per cubic foot to about 10 pounds per cubic foot.
