The infant support structure of claim 5, said first leg having a longitudinal axis, said first movable member being movable in a direction substantially perpendicular to said longitudinal axis, and said first movable member being selectively disposable in a first position engaging said first leg and a second position spaced from said first leg.7. The infant support structure of claim 6, said third movable member being movable in a direction at an angle with respect to said longitudinal axis of said first leg.8. The infant support structure of claim 7, movement of said third movable member along a direction substantially parallel to said longitudinal axis causing said first movable member to disengage from said first leg.9. The infant support structure of claim 5, said height adjustment mechanism including a biasing element, said biasing element biasing said first movable member into engagement with said first leg.10. The infant support structure of claim 5, said first leg including a plurality of openings, said first movable member being selectively engageable with said plurality of openings.11. The infant support structure of claim 5, said base defining a cavity, and said first movable member and said third movable member being disposed within said base cavity.12. The infant support structure of claim 5, movement of said third movable member causing said first movable member to disengage from said first leg and said second movable member to disengage from said second leg.13. An infant support structure comprising:a first base, said first base including a first height adjustment mechanism; a frame, said frame being coupled to said base, said frame including a first leg and a second leg, each of said first leg and said second leg being engageable with said first base and being selectively engageable by said height adjustment mechanism substantially simultaneously; a second base, said second base including a second height adjustment mechanism, said frame including a third leg and a fourth leg, said third and fourth legs being engageable by said second height adjustment mechanism; and a support, said support being coupled to said frame, a distance between said first base and said support and a distance between said second base and said support being adjustable upon activation of said first height adjustment mechanism and said second height adjustment mechanism; said first base being spaced from said second base a first distance when said frame is in a lowered configuration and said first base being spaced from said second base a second distance when said frame is in a raised configuration, said first distance being less than said second distance. 14. The infant support structure of claim 13, said legs of said frame being selectively disposable in retracted positions relative to said first and second bases when said frame is in said lowered configuration and in extended positions relative to said first and second bases when said frame is in said raised configuration.15. An infant support structure comprising:a frame, said frame including a first frame portion and a second frame portion, each of said first and second frame portions having an upper end and a lower end and having a length between said upper end and said lower end, said lower ends being configured to be placed on a support surface, said first frame portion including a first adjustment mechanism, said second frame portion including a second adjustment mechanism, said adjustment mechanisms being operable to enable a user to change the length of said first frame portion and the length of said second frame portion, said first frame portion including a first leg and a second leg, said first adjustment mechanism including an actuator and means for engaging said first leg, said actuator being operatively engageable with said means for engaging said first leg; and a support, said support being configured to support an infant, said support being coupled to said first and second frame portions proximate to said upper ends, said support being movable relative to the support surface in response to activation of said adjustment mechanisms. 16. The infant support structure of claim 15, said coupling member being configured to engage said first leg, and activation of said actuator causing said coupling member to disengage from said first leg.17. The infant support structure of claim 15, said coupling member being disposable in an extended position and in a retracted position relative to said first leg, said coupling member engaging said first leg while in said extended position.18. The infant support structure of claim 17, said coupling member being biased into said extended position.19. An infant support structure comprising:a front base, said front base including a first height adjustment mechanism, said first height adjustment mechanism including a first coupling mechanism and a first actuator; a rear base, said rear base including a second height adjustment mechanism, said second height adjustment mechanism including a second coupling mechanism and a second actuator; a frame, said frame including a front frame portion being coupled to said front base and a rear frame portion being coupled to said rear base, said front frame portion including a first leg and a second leg, said rear frame portion including a third leg and a fourth leg, said first leg and said second leg being engageable by said first coupling mechanism, said third leg and said fourth leg being engageable by said second coupling mechanism, movement of said first actuator disengages said first coupling member from said first leg and said second leg, and movement of said second actuator disengages said second coupling member from said third leg and said fourth leg; and a support, said support being coupled to said frame, the distances between said support and said bases being adjustable upon activation of said first and second height adjustment mechanisms. 20. The infant support structure of claim 19, said first coupling mechanism including a first elongate member and a second elongate member, said first actuator being operatively engageable with said first and second elongate members.21.
