A patient support comprising: a frame including a deck support and a step deck positioned on the deck support, the step deck having an upper deck, a lower deck, and a side wall, the upper deck being spaced apart from the lower deck to define a recess of the deck; a substantially rigid mattress section support located on the step deck; and means for aligning the mattress section support with a deck section. 9. The patient support of claim 4, further comprising a substantially non-rigid mattress supported on the step deck. 10. A patient support comprising: a frame including a deck support and a step deck positioned on the deck support, the step deck having an upper deck, a lower deck, and a side wall, the upper deck being spaced apart from the lower deck to define a recess of the deck; a mattress section support located on the step deck; means for aligning the mattress section support with a deck section; and a substantially non-rigid mattress supported on the step deck, the mattress including straps coupled thereto. 11. A patient support comprising: a frame including a deck support and a step deck positioned on the deck support, the step deck having an upper deck, a lower deck, and a side wall, the upper deck being spaced apart from the lower deck to define a recess of the deck; a mattress section support located on the step deck; and means for aligning the mattress section support with a deck section including tethers-removably coupled to a mattress. 12. A patient support comprising: a frame including a deck support and a step deck positioned on the deck support, the step deck having an upper deck, a lower deck, and a side wall, the upper deck being spaced apart from the lower deck to define a recess of the deck; a mattress section support located on the step deck; and a coupler coupled to the mattress section support. 13. The patient support of claim 12, wherein the coupler orients the mattress section support with a deck section. 14. The patient support of claim 12, wherein the upper deck includes a lip extending from the side wall. 15. The patient support of claim 12, wherein the step deck is coupled to a substantially planar foot section. 16. The patient support of claim 12, wherein the mattress section support is substantially rigid. 17. The patient support of claim 12, wherein the mattress section support is substantially non-rigid. 18. The patient support of claim 17, wherein the mattress includes a strap coupled thereto. 19. The patient support of claim 18, wherein the coupler removably couples to the straps. 20. A method of converting a patient support deck from a step deck having a recess to a substantially flat deck comprising the steps of: removing a first mattress section support and a first mattress simultaneously; placing a second mattress section support upon a step deck to substantially fill the recess in the step deck; and placing a second mattress upon the step deck and the second mattress section support. 21. The method of claim 20, wherein placing the mattress section support upon the step deck configures the step deck to receive a mattress of substantially uniform thickness thereon. 22.
