Zoned Spring Mattress That Can Be Compactly Compressed, Folded and Rolled

A mattress comprising:

• a first lateral region of a spring layer, wherein the first lateral region comprises coils that are connected to one another by helical-shaped wires;
• a second lateral region of the spring layer, wherein the second lateral region comprises individual coils each enclosed in a fabric pocket, wherein a central axis of the mattress passes through the second lateral region, wherein the mattress has a top, a bottom, an upper side and a lower side;
• a third lateral region of the spring layer, wherein the third lateral region comprises coils that are connected to one another by helical-shaped wires, wherein the helical-shaped wires are oriented within the first lateral region and the third lateral region longitudinally from the top to the bottom of the mattress, wherein the third lateral region is disposed between the second lateral region and the bottom of the mattress, wherein the first lateral region is disposed between the second lateral region and the top of the mattress;
• and
• a mattress cover that entirely encloses the first lateral region, the second lateral region and the third lateral region.

A method comprising:

• compressing a mattress that has a zoned spring layer, wherein air is removed from an airtight wrapper surrounding the mattress as the mattress is compressed, wherein the zoned spring layer has a central axis, a top, a bottom, a first lateral region, a second lateral region and a third lateral region, wherein the central axis passes through the second lateral region, wherein the first lateral region is disposed between the second lateral region and the top of the mattress, wherein the third lateral region is disposed between the second lateral region and the bottom of the mattress, wherein the second lateral region includes pocket springs comprised of individual metal coils each encased in fabric, wherein each of the first and third lateral regions includes coils that are connected to one another by helical-shaped wires, and wherein the helical-shaped wires are oriented within the first and third lateral regions longitudinally from the top to the bottom of the mattress;
• folding the compressed mattress over itself at the central axis;
• and
• rolling the compressed and folded mattress about a rolling axis that is perpendicular to the central axis, wherein the helical-shaped wires are oriented parallel to the rolling axis.
