What is claimed is: 1. A variable width chair bed having a head end and a foot end opposing the head end, and a first side and a second side opposing the first side, the chair bed comprising: a frame; a main deck supported on the frame, the main deck having a first deck section, a second deck secti
What is claimed is: 1. A variable width chair bed having a head end and a foot end opposing the head end, and a first side and a second side opposing the first side, the chair bed comprising: a frame; a main deck supported on the frame, the main deck having a first deck section, a second deck section and a third deck section, the first deck section located adjacent the head end, the third deck section located adjacent the foot end, and the second deck section between the first deck section and the third deck section, wherein the first deck section is moveable from a generally horizontal position to a more vertical back-support position, and wherein the third deck section at the foot end of the bed is moveable from a generally horizontal position to a substantially vertical position extending downwardly below the frame; a first deck extender section extending from the first side of one of the first deck section and the second deck section, and a second deck extender section extending from the second side of one of the first deck section and the second deck section, wherein the first and second deck extender sections are each independently moveable from a first retracted position located a first distance from a centerline of the main deck to a second expanded position located a second distance from the centerline of the main deck, the second distance being greater than the first distance; a first supplemental mattress connected to the first deck extender section in the first and second position, and a second supplemental mattress connected to the second deck extender section in the first and second position; and, a first side rail directly connected to the first deck extender section and a second side rail directly connected to the second deck extender section, the first side rail being positioned in a vertical plane adjacent an edge of the first deck extender section when the first deck extender section is in the first retracted position and in the second expanded position to provide a barrier at the first deck extender section in both the first retracted position and in the second expanded position, and the second side rail being positioned in a vertical plane adjacent an edge of the second deck extender section when the second deck extender section is in the first retracted position and in the second expanded position to provide a barrier at the second deck extender section in both the first retracted position and in the second expanded position. 2. The chair bed of claim 1, further comprising a first supplemental deck rotatably connected to the first deck extender section, and a second supplemental deck rotatably connected to the second deck extender section, the first supplemental mattress being connected to the first supplemental deck and the second supplemental mattress being connected to the second supplemental deck. 3. The chair bed of claim 1, wherein the first and second deck extender sections are connected to the main deck at a position below a deck surface of the main deck. 4. The chair bed of claim 1, further comprising a siderail connected to the bed adjacent the third deck section. 5. The chair bed of claim 1, wherein a plurality of the supplemental mattresses are moveable from a first position wherein a portion of the supplemental mattresses are under a plane of the main deck to a second position wherein a portion of the supplemental mattresses are over the plane of the main deck. 6. The chair bed of claim 5, wherein the supplemental mattresses are rotatably connected to their respective deck extender sections, the supplemental mattresses rotatably moving from the first position to the second position. 7. The chair bed of claim 1, further comprising a third deck extender section extending from the first side of the other of the first deck section and the second deck section, and a fourth deck extender section extending from the second side of the other of the first deck section and the second deck section, wherein the third and fourth deck extender sections are each independently moveable from a first retracted position located a distance from a centerline of the main deck to a second expanded position located a greater distance from the centerline of the main deck. 8. The chair bed of claim 7, further comprising a first supplemental mattress connected to the first deck extender section, a second supplemental mattress connected to the second deck extender section, a third supplemental mattress connected to the third deck extender section, and a fourth supplemental mattress connected to the fourth deck extender section. 9. The chair bed of claim 1, wherein the first deck extender section slidably engages the main deck to move from the first retracted position to the second expanded position, and wherein the second deck extender section slidably engages the main deck to move from the first retracted position to the second expanded position. 10. The chair bed of claim 9, further comprising a handle connected to the deck extender sections, the handle having a release member to release the deck extenders from securement in the first retracted position. 11. The chair bed of claim 1, the first and second side rails movably connected to the respective deck extender sections to allow the first and second side rails to move between a raised position and a lowered position. 12. A variable width bed having a head end and a foot end opposing the head end, and a first side and a second side opposing the first side, the bed comprising: a frame; a deck supported on the frame; a mattress supported on the deck; a first deck extender section extending from the first side of the deck, and a second deck extender section extending from the second side of the deck, wherein the first and second deck extender sections are each independently moveable from a first retracted position located a first distance from a centerline of the deck to a second expanded position located a second distance from the centerline of the deck, and wherein the second distance is greater than the first distance; a first supplemental mattress connected to the first deck extender section in the first and second position, and a second supplemental mattress connected to the second deck extender section in the first and second position, wherein in the first retracted position the first and second supplemental mattresses do not extend beyond a width of the mattress; and, a first side rail directly connected to the first deck extender section and a second side rail directly connected to the second deck extender section, the first side rail being positioned in a vertical plane adjacent an edge of the first deck extender section when the first deck extender section is in the first retracted position and in the second expanded position to provide a barrier adjacent the first deck extender section in both the first retracted position and in the second expanded position, and the second side rail being positioned in a vertical plane adjacent an edge of the second deck extender section when the second deck extender section is in the first retracted position and in the second expanded position to provide a barrier adjacent the second deck extender section in both the first retracted position and in the second expanded position. 13. A variable width patient support, comprising: a deck supported by a frame; a main mattress portion supported on the deck; a deck extender section extending from a side of the deck, the deck extender section being independently movable from a first retracted position located a first distance from a centerline of the deck to a second expanded position located a second distance from the centerline of the deck, the second distance being greater than the first distance; and, a handle directly connected to the deck extender section, the handle having a biasing member to release the deck extender section from securement in the first retracted position. 14. The patient support of claim 13, further comprising a supplemental mattress portion connected to the deck extender section in both the first position and the second position. 15. The patient support of claim 13, wherein separate deck extender sections are provided at opposing first and second sides of the main mattress portion, and wherein the separate deck extender sections at the opposing sides are independently moveable from the first position to the second position. 16. The patient support of claim 13, wherein the main mattress portion has a head section and a seat section, and further comprising independent deck extender sections at each of the head and seat sections.
