A mattress is disclosed. The mattress includes a support layer, a comfort layer arranged supported on the support layer and a support structure sandwiched between the support layer and the comfort layer. The support structure includes a plurality of first bars extending in a longitudinal direction and arrayed in a lateral direction and at least one second bar coupled to the plurality of first bars and supported on the plurality of first bars. The at least one second bar extends in the lateral direction and is configured to facilitate a flexing of the plurality of first bars in convex shapes when a person lies on the mattress to support a lumbar region of the person.
1 . A mattress, comprising:
a support layer;
a comfort layer arranged supported on the support layer; and
a support structure sandwiched between the support layer and the comfort layer, the support structure being configured to support a lumbar region of a person when the person lies on the mattress, the support structure including:
a plurality of first bars extending in a longitudinal direction and arrayed in a lateral direction; and
at least one second bar extending in the lateral direction, the at least one second bar coupled to and supported on middle portions of the plurality of first bars and absent from oppositely defined ends of the plurality of first bars such that connections of the at least one second bar with the plurality of first bars act as fulcrums for the plurality of first bars causing said ends of the plurality of first bars to flex or bend relative to the fulcrums to facilitate a flexing of the plurality of first bars in convex shapes.
2 . The mattress of claim 1 , wherein the middle portions are arranged to flex upwardly relative to ends of the plurality of first bars to support the lumbar region of the person.
3 . The mattress of claim 1 , wherein the plurality of first bars is arranged such that first longitudinal ends of the plurality of first bars are adapted to be arranged underneath a shoulder region of the person when the person lies on the mattress, and second longitudinal ends of the plurality of first bars are adapted to be arranged underneath a hip region of the person.
4 . The mattress of claim 1 , wherein the support structure further includes a cover to enclose the plurality of first bars and the plurality of second bars.
5 . The mattress of claim 4 , wherein the cover includes a plurality of first sleeves configured to receive and enclose the plurality of first bars.
6 . The mattress of claim 4 , wherein the cover includes at least one second sleeve extending substantially perpendicular to the plurality of first sleeves and configured to receive and enclose the one or more of the second bars.
7 . The mattress of claim 6 , wherein the at least one second sleeve includes a plurality of second sleeves arrayed in the longitudinal direction and adapted to removably receive the at least one second bar.
8 . The mattress of claim 1 , wherein one or more of plurality of first bars includes two carbon fiber strips laminated together.
9 . The mattress of claim 1 , wherein a cross-sectional area of one or more of the plurality of first bars varies from a central/middle portion of the first bars towards ends of the first bar.
10 . The mattress of claim 1 further including:
a plurality of first sleeves configured to correspondingly receive and enclose the plurality of first bars; and
a plurality of second sleeves coupled to the plurality of first sleeves, the plurality of second sleeves configured to selectively receive and enclose the at least one second bar such that the at least one second bar is positionable at a desired location with respect to the plurality of first bars to achieve variation in a shape of the support structure, facilitating desired support to the lumbar region of the person when the person lies on the mattress.
