Abstract

A bed has a mattress with a mattress top, a mattress bottom, and a mattress perimeter. The mattress includes a mattress cover surrounding the mattress. The mattress cover includes a first stretch fabric around the mattress perimeter of the mattress. The first stretch fabric has a first predominant stretch direction that is stretchable in a direction parallel to the mattress top. A multidirectional stretch fabric is positioned on the mattress top.

First claim

What is claimed is:

1. A system comprising:
a bed having a mattress with a mattress top, a mattress bottom, and a mattress perimeter, wherein the mattress comprises:
a mattress cover that is part of the mattress and that surrounds each of the mattress top, the mattress bottom, and the mattress perimeter of the mattress, the mattress cover comprising:
a first 2-way stretch fabric around the mattress perimeter of the mattress, the first 2-way stretch fabric having a stretch direction that is stretchable in a direction parallel to the mattress top and having limited or no stretch in a direction perpendicular to the mattress top;
a 4-way stretch fabric positioned on the mattress top; and
a second 2-way stretch fabric positioned between the first 2-way stretch fabric and the 4-way stretch fabric, the second 2-way stretch fabric having a second stretch direction that is stretchable in a direction between an edge of the 4-way stretch fabric and an edge of the first 2-way stretch fabric, the second 2-way stretch fabric having limited or no stretch in a perpendicular direction that is perpendicular to the second stretch direction.

2. The system of claim 1 , wherein the first 2-way stretch fabric and the 4-way stretch fabric each comprise knit materials having different properties from one another.

3. The system of claim 1 , wherein the first 2-way stretch fabric is a woven laminated fabric.

4. The system of claim 1 , wherein the second 2-way stretch fabric is at least partially on the mattress top and at least partially on the mattress perimeter.

5. The system of claim 1 , wherein the mattress includes a left side and a right side, the first 2-way stretch fabric comprising a first portion along the left side that is narrower than a height of the mattress and a second portion along the right side that is narrower than the height of the mattress.

6. The system of claim 5 , wherein the first portion and the second portion are the same height.

7. The system of claim 5 , wherein the first portion and the second portion include a bottom portion that is in-line with a bottom side of the mattress, the second 2-way stretch fabric extending between the 4-way stretch fabric to the edge of the first 2-way stretch fabric, the second 2-way stretch fabric being both on the mattress top and at least partially along the left side and the right side.

8. The system of claim 5 , wherein the first portion and the second portion each comprise a head section nearer a head of the bed and a foot section nearer a foot of the bed, each of the head sections and the foot sections having a height substantially similar to a height of the mattress.

9. A mattress cover configured to entirely surround a mattress, the mattress cover comprising:
a first two-way stretch fabric configured to be positioned around a perimeter of the mattress, the first two-way stretch fabric configured to stretch in a direction parallel to a mattress top of the mattress and that does not stretch in a direction perpendicular to the mattress top;
a four-way stretch fabric configured to be positioned on the mattress top; and
a second two-way stretch fabric positioned between the first two-way stretch fabric and the four-way stretch fabric, the second two-way stretch fabric having a second stretch direction that is stretchable in a direction between an edge of the four-way stretch fabric and an edge of the first two-way stretch fabric, the second two-way stretch fabric having limited or no stretch in a perpendicular direction that is perpendicular to the second stretch direction.

10. The mattress cover of claim 9 , wherein the second two-way stretch fabric is configured to be positioned at least partially on the mattress top.

11. The mattress cover of claim 9 , wherein the second two-way stretch fabric is configured to stretch more than the first two-way stretch fabric and the four-way stretch fabric.

12. The mattress cover of claim 9 , wherein the second two-way stretch fabric has a thicker weight knit than the first two-way stretch fabric and the four-way stretch fabric.

13. The mattress cover of claim 9 , the first two-way stretch fabric comprising a first portion configured to be positioned along a left mattress side, the first portion being narrower than a height of the mattress, the first two-way stretch fabric comprising a second portion configured to be positioned along a right mattress side, the second portion being less than the height of the mattress.

14. The mattress cover of claim 13 , wherein the first portion and the second portion each comprise a head section configured to be nearer a head of the mattress and a foot section configured to be nearer a foot of the mattress, each of the head sections and the foot sections having a height substantially similar to a height of the mattress.

15. The mattress cover of claim 9 , wherein the mattress cover further comprises:
a bottom fabric connected to the first two-way stretch fabric and extending from a bottom edge of the perimeter to cover a mattress bottom.

16. The mattress cover of claim 15 , wherein the bottom fabric comprises a non-stretch woven material.

17. The mattress cover of claim 1 , wherein the first 2-way stretch fabric has the stretch direction that is stretchable in the direction parallel to the mattress top around the entire perimeter of the mattress.

18. The mattress cover of claim 1 , wherein the first 2-way stretch fabric extends between the mattress top and the mattress bottom across at least a portion of the mattress perimeter.

19. A mattress defining a mattress bottom, a mattress top, and mattress sides extending perpendicularly between the mattress bottom and the mattress top, the mattress comprising:
a fabric assembly completely surrounding the mattress, the fabric assembly comprising:
a top panel positioned on the mattress top, the top panel comprising a four-way stretch fabric, the four-way stretch fabric configured to stretch only in a plane defined by the mattress top;
a bottom panel positioned on the mattress bottom, the bottom panel comprising a non-stretch fabric;
a plurality of side panels coupled to the top panel and the bottom panel, the plurality of side panels positioned on the mattress sides, the plurality of side panels each comprising a two-way stretch fabric, the two-way stretch fabric configured to stretch in a direction only between the plurality of side panels in a plane defined by the mattress sides and parallel to the mattress top and the mattress bottom, the two-way stretch fabric being non-stretchable between the mattress top and the mattress bottom; and
a two-way stretch fabric positioned between the plurality of side panels and the top panel, the two-way stretch fabric having a second stretch direction that is stretchable in a direction between an edge of the top panel and an edge of the plurality of side panels, the two-way stretch fabric having limited or no stretch in a perpendicular direction that is perpendicular to the second stretch direction.

20. A fabric assembly configured to completely surround a mattress, the fabric assembly comprising:
a four-way stretch fabric, the four-way stretch fabric configured to stretch predominately in a plane corresponding to a top surface of the mattress, the four-way stretch fabric at least partially covering the top surface of the mattress;
a bottom fabric extending entirely across a bottom surface of the mattress parallel to the top surface;
a first two-way stretch fabric, the first two-way stretch fabric configured to stretc
