Abstract

A sleep system comprises an air posturizing module having a case, the case comprising a first case section extending medially along a length of the case to define a movable first section, a second case section adjacent to the first case section and extending along a length of the case to define a movable second section, a third case section defining a third posturing section, a fourth case section extending medially along a length of the case to define a movable third section, and a fifth case section extending medially along a length of the case to define a movable fourth section. One or more first air chambers are carried in the first, third and fourth case sections to provide a first sleep area, and one or more second air chambers are carried in the second, third, and fifth module sections to provide a second sleep area.

First claim

What is claimed is:

1 . A sleep system, comprising:
a mattress comprising:
a first sleep area for a first occupant, the first sleep area comprising:
a first movable upper section and a first movable lower section longitudinally aligned with the first movable upper section; and
a first portion of a common middle section positioned between the first movable upper section and the first movable lower section of the first sleep area;

a second sleep area for a second occupant, the second sleep area comprising:
a second movable upper section adjacent to the first movable upper section, and a second movable lower section adjacent to the first movable lower section and longitudinally aligned with the second movable upper section; and
a second portion of the common middle section positioned between the second movable upper section and the second movable lower section, the first portion and the second portion extending between the first sleep area and the second sleep area so as to join the first sleep area to the second sleep area at the common middle section to form a joined substantially unitary middle section;
a first medial split that extends as a first straight line between the first movable upper section and the second movable upper section;
a second medial split that extends as a second straight line between the first movable lower section and the second movable lower section; and
a mattress cover covering the mattress and comprising fabric to enclose each of the first and second movable upper sections, the first and second movable lower sections, and the first and second portions of the common middle section wherein portions of the fabric are positioned in the first and second medial splits to allow for independent articulation of each of the first and second movable upper sections and the first and second movable lower sections.

2 . The sleep system of claim 1 , wherein the first medial split and the second medial split are coplanar.

3 . The sleep system of claim 1 , wherein the mattress cover wraps around the first sleep area and the second sleep area.

4 . The sleep system of claim 1 , wherein the mattress cover encloses all of the first sleep area and all of the second sleep area.

5 . The sleep system of claim 1 , further comprising an articulation system for articulating the first movable upper section, the first movable lower section, the second movable upper section, and the second movable lower section.

6 . A sleep system, comprising:
a mattress comprising:
a first sleep area for a first occupant, the first sleep area comprising:
a first movable upper section and a first movable lower section longitudinally aligned with the first movable upper section; and
a first portion of a common middle section positioned between the first movable upper section and the first movable lower section of the first sleep area;

a second sleep area for a second occupant, the second sleep area comprising:
a second movable upper section adjacent to the first movable upper section, and a second movable lower section adjacent to the first movable lower section and longitudinally aligned with the second movable upper section; and
a second portion of the common middle section positioned between the second movable upper section and the second movable lower section, the first portion and the second portion extending between the first sleep area and the second sleep area so as to join the first sleep area to the second sleep area at the common middle section to form a joined substantially unitary middle section;

a first medial split that extends as a first straight line between the first movable upper section and the second movable upper section;
a second medial split that extends as a second straight line between the first movable lower section and the second movable lower section; and
a mattress cover covering the mattress and further comprising a friction reducing material disposed along a plurality of interior side surfaces of the mattress defined by the first medial split and the second medial split.

7 . The sleep system of claim 6 , wherein the friction reducing material is configured to allow the plurality of interior side surfaces to slide freely or relatively freely over one another when one or both of the first movable upper section and the second movable upper section are moved relative to each other or when one or both of the first movable lower section and the second movable lower section are moved relative to each other.

8 . The sleep system of claim 6 , wherein the friction reducing material comprises a polytetrafluoroethylene fiber, a lycra spandex fiber, or a polyurethane-polyrea copolymer.

9 . The sleep system of claim 6 , wherein a coefficient of friction defines a friction force between the plurality of interior side surfaces, and wherein the friction reducing material has a lower coefficient of friction than a second material positioned on a top surface of the mattress.

10 . The sleep system of claim 9 , wherein the coefficient of friction is sufficiently low so as to avoid deformation of the mattress cover when the first movable upper section and the second movable upper section are moved relative to each other or when one or both of the first movable lower section and the second movable lower section are moved relative to each other.

11 . A mattress comprising:
a first sleep area for a first occupant, the first sleep area comprising a first movable upper section and a first movable lower section longitudinally aligned with the first movable upper section; a second sleep area for a second occupant, the second sleep area comprising a second movable upper section adjacent to the first movable upper section, and a second movable lower section adjacent to the first movable lower section and longitudinally aligned with the second movable upper section; a first medial split that extends as a first straight line between the first movable upper section and the second movable upper section, the first medial split defining a first plurality of interior side surfaces; a second medial split that extends as a second straight line between the first movable lower section and the second movable lower section, the second medial split defining a second plurality of interior side surfaces; a friction reducing material disposed along the first plurality of interior side surfaces; a common middle section extending between the first sleep area and the second sleep area so as to join the first sleep area to the second sleep area at the common middle section to form a joined substantially unitary middle section, the common middle section being positioned between the first movable upper section and the first movable lower section of the first sleep area and positioned between the second movable upper section and the second movable lower section of the second sleep area; and a mattress cover covering the mattress.

12 . The mattress of claim 11 , further comprising an articulation system configured to separately articulate each of the first movable upper section, the first movable lower section, the second movable upper section, and the second movable lower section.

13 . The mattress of claim 11 , wherein the first medial split and the second medial split are coplanar.

14 . The mattress of claim 11 , wherein the mattress cover wraps around the first sleep area and the second sleep area.

15 . The mattress of claim 11 , wherein the mattress cover encloses the first sleep area and the second sleep area.

16 . The mattress of claim 11 , wherein the mattress c
