a patient support apparatus adapted to provide a bed frame, the patient support apparatus including a deck adapted to underlie a support surface, the deck being made up of a seat deck section, a foot deck section mounted to move relative to the seat deck section, and a head deck section mounted to pivot about an axis and to slide away from the seat deck section forming a gap between the seat deck section and the head deck section, and

a patient support surface adapted to provide a mattress, the patient support surface including a plurality of internal components, a ticking that provides a cover encasing the internal components, and a plurality of lugs configured to couple the patient support surface to the deck for movement therewith,

wherein the plurality of lugs include a first pair of lugs coupled to a head-end section of the ticking that extend from the ticking into apertures formed in the head deck section to couple the head-end section of the ticking to the head deck section for movement therewith during sliding of the head deck section away from the seat deck section, a second pair of lugs that extend from a foot-end section of the ticking into apertures formed in the foot deck section to couple the foot-end section of the ticking to the foot deck section for movement therewith relative to the seat deck section, and a third pair of lugs that extend from a section of the ticking between the head-end section and the foot-end section into apertures formed in the seat deck section to couple the ticking to the seat deck section.

2. The system of claim 1 , wherein each of the plurality of lugs includes a stem that extends from the ticking through apertures formed in the deck and a ball arranged below the deck opposite the ticking of the support surface.

3. The system of claim 2 , wherein at least some of the balls included in the plurality of lugs are trapped below the deck to resist removal of the lugs from the apertures in response to a force pulling the support surface away from the deck in a direction perpendicular to a plane defined by a corresponding section of the deck.

4. The system of claim 2 , wherein at least some of the apertures formed in the deck into which the lugs extend are keyhole slots shaped to have a wide portion sized to allow a ball included in a lug to pass through the deck and a narrow portion sized to block a ball included in a lug from passing through the deck.

5. The system of claim 4 , wherein the wide portion of each of the keyhole slots is located inwardly of the corresponding narrow portion nearer a center line of the deck arranged midway between the left side and the right side of the patient support system.

6. They system of claim 1 , wherein the ticking is shaped to include a series of folds arranged between the first pair of lugs and the third pair of lugs along an axis that extends from the head end of the system to the foot end of the system, the series of folds configured to accommodate lengthening of the ticking caused in response to sliding of the head deck section away from the seat deck section to form the gap between the seat deck section and the head deck section.

7. The system of claim 6 , wherein the first pair of lugs each include a stem that extends from the ticking through apertures formed in the deck and a ball arranged below the deck opposite the ticking of the support surface.

8. The system of claim 1 , wherein the support surface includes a trunk carrying pneumatic and electrical lines that extends downwardly from a bottom surface of the ticking to be received by the patient support apparatus when the support surface is mounted on the patient support apparatus.

9. The system of claim 8 , wherein the trunk is arranged to extend between lugs included in the third pair of lugs along an axis that extends laterally from the left side of the system to the right side of the system.

10. The system of claim 8 , wherein the seat-deck section is formed to include a channel sited to receive the trunk of the support surface when the support, surface is mounted on the patient support apparatus.

11. A patient support system having a head end, a foot end, a left side, and a right side, the system comprising

a patient support apparatus, the patient support apparatus including a deck adapted to underlie a support surface, the deck being made up of a seat deck section and a head deck section, the head deck section mounted to pivot about an axis and to slide away from the seat deck section so as to form a gap between the seat deck section and the head deck section, and

a patient support surface including a plurality of internal components, a ticking that provides a cover encasing the internal components, and a plurality of lugs configured to couple the patient support surface to the deck for movement therewith,

wherein the plurality of lugs include a pair of lugs coupled to a head-end section of the ticking that extend from the ticking into apertures formed in the head deck section to couple the head-end section of the ticking to the head deck section for movement therewith during sliding of the head deck section away from the seat deck section.

12. The system of claim 11 , wherein each of the plurality of lugs includes a stem that extends from the ticking through apertures formed in the deck and a ball arranged below the deck opposite the ticking of the support surface.

13. The system of claim 12 , wherein the balls included in the plurality of lugs are trapped below the deck to resist removal of the lugs from the apertures in response to a force pulling the support surface away from the deck in a direction generally perpendicular to a plane defined by the head deck section of the deck.

14. The system of claim 13 , wherein the apertures formed in the head deck section into which the lugs extend are keyhole slots shaped to have a wide portion sized to allow a ball included in a lug to pass through the deck and a narrow portion sized to block a ball included in a lug from passing through the deck.

15. The system of claim 14 , wherein the wide portion of each of the keyhole slots is located inwardly of the corresponding narrow portion nearer a center line of the deck arranged midway between the left side and the right side of the patient support system.

16. The system of claim 11 , wherein the plurality of lugs includes a second pair of lugs that extend into apertures formed in the seat deck section to couple the ticking to the seat deck section to couple the ticking to the seat deck section.

17. The system of claim 16 , wherein each of the plurality of lugs includes a stem that extends from the ticking through apertures formed in the deck and a ball arranged below the deck opposite the ticking of the support surface.

18. The system of claim 16 , wherein the ticking is shaped to include a series of folds arranged between the pair of lugs received in the head deck section and the pair of lugs received in the seat deck section along an axis that extends from the head end of the system to the foot end of the system, the series of folds configured to accommodate lengthening of the ticking caused in response to sliding of the head deck section away from the seat deck section to form the gap between the seat deck section and the head deck section.

19. The system of claim 16 , wherein deck of the patient support apparatus includes a foot deck section mounted for movement relative to the seat deck section, and wherein the plurality of lugs includes a third pair of lugs coupled to a foot-end section of the ticking that extend from the ticking into apertures formed in the foot deck section to couple the foot-end section of the ticking to the foot deck section for movement therewith during movement of the foot deck section relative to the seat deck section.

20. The system of claim 19 , wherein each of the plurality of lugs includes a stem that extends from the ticking through apertures formed in the deck and a ball arranged below the deck opposite the ticking of the support surface, and wherein the balls included in the plurality of lugs are trapped below the deck to resist removal of the lugs from the apertures in response to a force pulling the support surface away from the deck in a direction generally perpendicular to a plane defined by the corresponding section of the deck that receives the lug.
