1. A mattress cover for coupling to a mattress having an upper surface, a lower surface, sides, and an inflatable bladder for adjusting a size of the mattress for supporting a patient, the mattress cover comprising:
a patient support portion configured to cover the upper surface of the mattress;
a bottom portion coupled to the patient support portion and configured to cover the lower surface of the mattress;
peripheral portions extending between the patient support portion and the bottom portion such that the mattress cover is configured to substantially encase the mattress; and
an augmenting feature associated with one of the peripheral portions and being configured to move between a stored configuration in the absence of expansion of the inflatable bladder, and a deployed configuration having an expanded size in response to expansion of the inflatable bladder, the augmenting feature including a resilient member configured to bias the augmenting feature toward the stored configuration.
