Abstract
Compressible mattress assemblies for bed in a box applications generally include a first foam layer and a second foam layer, wherein the first foam layer has a thickness less than the second foam layer and has a property and/or a foam material that is different from the second foam layer. In other embodiments, the compressible mattress assemblies consist of a pocketed microcoil array intermediate the first and second polymeric foam layers.
Claims18
A compressible mattress assembly for a bed in a box application, the compressible mattress assembly including a length and a width dimension, wherein the length is greater than the width, comprises:
- a first foam layer;
- a second foam layer underlying the first foam layer;
- and
- a topper layer overlying the first foam layer;
- wherein the first foam layer has a thickness greater than the second foam layer, a higher indention load deflection, and further comprises side rails extending only along a length on each side thereof,
- wherein the side rails comprise a compressible foam having an indention force deflection greater than the indention load deflection of the first foam layer, and wherein the first foam layer and the side rails have a length and a width dimension substantially equal to a length and a width dimension of the second foam layer, and wherein the side rails are adhesively affixed to a top surface of the second foam layer and to a bottom surface of the topper layer such that vertical surfaces intermediate the side rail and the first foam layer are free from adhesive, wherein the compressible mattress is configured to be folded and rolled for packaging in a box and wherein the side rails do not bind when removed from the box and decompressed.
A compressible mattress assembly for a bed in a box application, the compressible mattress assembly comprising:
- a foam topper layer;
- a first foam layer underlying the foam topper layer,
- a second foam layer underlying the first foam layer, and
- a fabric covering encapsulating the first and second foam layers, wherein a selected one of the first and second foam layers comprises a thermally conductive material and/or a phase change material in and proximate to at least a surface thereof,
- wherein the first foam layer comprises compressible foam side rails extending only along a length on each side thereof, wherein the first foam layer and the side rails have a length and a width dimension substantially equal to a length and a width dimension of the second foam layer and the foam topper layer, wherein the side rails are adhesively affixed only to a top surface of the second foam layer and to a bottom surface of the topper layer such that vertical surfaces intermediate the side rail and the first foam layer are free from adhesive, and
- wherein the first foam layer has a thickness greater than the second foam layer and an indention load deflection less than the second layer, and wherein the side rails have an indention force deflection greater than the indention load deflection of the first foam layer, wherein the compressible mattress is configured to be folded and rolled for packaging in a box and wherein the side rails do not bind when removed from the box and.
