Abstract

A mattress comprises a cover defining an interior region, a first foam section located in the interior region of the cover, and a second foam section located in the interior region of the cover adjacent the first foam section. The first foam section includes a first angled surface and the second foam section includes a second angled surface configured to abut the first angled surface.

Claims

1. A mattress comprising:

a cover defining an interior region;

a first foam section located in the interior region of the cover, the first foam section including a bottom surface, a first end wall extending generally perpendicular to the bottom surface of the first foam section, and a first angled surface extending transverse to the first end wall; and

a second foam section located in the interior region of the cover adjacent the first foam section, the second foam section including a bottom surface, a second end wall extending generally perpendicular to the bottom surface of the second foam section, and a second angled surface extending transverse to the second end wall, the first angled surface being configured to abut the second angled surface.

2. The mattress of claim 1, wherein the mattress has a head end and a spaced apart foot end defining a length dimension and spaced apart first and second sides defining a width dimension, the first foam section having a width dimension substantially equal to the width dimension of the mattress, and the second foam section having a width dimension substantially equal to the width dimension of the mattress.

3. The mattress of claim 1, further comprising a foam base located in the interior region of the cover below the first and second foam sections.

4. The mattress of claim 3, further comprising a plurality of fasteners configured to couple the first and second foam sections to the foam base.

5. The mattress of claim 1, further comprising a shear cover configured to be located over the first and second foam sections, the shear cover having a low coefficient of friction.

6. The mattress of claim 1, wherein the second foam section includes a third end wall extending generally perpendicular to the bottom surface of the second foam section, and a third angled surface extending transverse to the third end wall, and further comprising a third foam section located in the interior region of the cover adjacent the second foam section, the third foam section including a bottom surface, a fourth end wall extending generally perpendicular to the bottom surface of the third foam section, and a fourth angled surface extending transverse to the fourth end wall, the third angled surface being configured to abut the fourth angled surface.

7. The mattress of claim 1, wherein at least one of the first and second foam sections includes a central foam portion and side foam portions extending along opposite sides of the central foam portion, the side foam portions having a density greater than the central foam portion.

8. The mattress of claim 1, wherein at least one of the first and second foam sections includes a top surface formed to include a plurality of transversely extending notches.

9. The mattress of claim 1, wherein the mattress has a head end and a spaced apart foot end defining a length dimension and spaced apart first and second sides defining a width dimension, the first and second foam sections each having a central foam portion and first and second side foam portions coupled to and extending along opposite sides of the central foam portion, the first and second side foam portions each having a firmness greater than a firmness of the central foam portion so that the first and second side foam portions of the first and second foam sections cooperate to define first and second borders extending along the first and second sides of the mattress, respectively, between the head end and the foot end of the mattress.

10. The mattress of claim 1, wherein the first angled surface is configured to overlap the second end wall.

11. The mattress of claim 1, wherein at least one of the foot, head and seat foam sections includes a central foam portion and side foam portions extending along opposite sides of the central foam portion, the side foam portions having a density greater than the central foam portion.

12. The mattress of claim 1, wherein the mattress has a head end and a spaced apart foot end defining a length dimension and spaced apart first and second sides defining a width dimension, the foot, head and seat foam sections each having a central foam portion and first and second side foam portions coupled to and extending along opposite sides of the central foam portion, the first and second side foam portions each having a firmness greater than a firmness of the central foam portion so that the first and second side foam portions of the foot, head and seat foam sections cooperate to define first and second borders extending along the first and second sides of the mattress, respectively, between the head end and the foot end of the mattress.

13. The mattress of claim 1, wherein the second and third angled surfaces are configured to overlap the first and fourth end walls, respectively.

14. A mattress comprising:

a cover having an interior region, a head end, and a foot end;

a foot foam section located adjacent the foot end of the cover, the foot foam section having a bottom surface and a head end formed to include a first angled edge surface configured to extend at a non-perpendicular angle relative to the bottom surface of the foot foam section;

a head foam section located adjacent the head end of the cover, the head foam section having a bottom surface and a foot end formed to include a second angled edge surface configured to extend at a non-perpendicular angle relative to the bottom surface of the head foam section; and

a seat foam section located between the foot and head foam sections, the seat foam section having a bottom surface, a foot end formed to include a third angled edge surface, and a head end formed to include a fourth angled edge surface, the third and fourth angled edge surfaces each being configured to extend at a non-perpendicular angle relative to the bottom surface of the seat foam section, the first angled edge surface being configured to abut the third angled edge surface and the second angled edge surface being configured to abut the fourth angled edge surface.

15. The mattress of claim 14, further comprising a foam base located in the interior region of the cover below the foot, head and seat foam sections.

16. The mattress of claim 15, further comprising a plurality of fasteners configured to couple the foot, head and seat foam sections to the base.

17. The mattress of claim 14, further comprising a shear cover configured to be located over the foot, head and seat foam sections, the shear cover having a low coefficient of friction.

18. The mattress of claim 14, wherein at least one of the foot, head and seat foam sections includes a central foam portion having a top surface formed to include a plurality of transversely extending notches.

19. A mattress apparatus comprising:

a cover having an interior region and a bottom surface;

a mattress core located in the interior region of the cover;

at least one pocket formed on the bottom surface of the cover; and

a magnet located in each of the at least one pockets.

20. The apparatus of claim 19, wherein the mattress core includes foam base having a head end and a foot end, a foot foam section located adjacent to the foot end of the base, a head foam section located adjacent to the head end of the base, a seat foam section located between the foot and head foam sections, and a plurality of fasteners configured to couple the foot, head and seat foam sections to the base.
