Patent ID: 8347436

Claim:
A mattress system comprising: a crib having an exterior surface, a top surface, a bottom surface, and a cavity defined by an interior surface; first and second attachment members joined to the crib interior surface; a first fluid bladder system (a) having an upper surface and a lower surface, (b) positioned within the cavity, (c) attached to the crib interior surface through the first and second attachment members so the crib restrains a patient from falling off the mattress system when the first fluid bladder system entire top surface is not in the same plane or above the crib's top surface, and (d) that provides a first cushion therapy selected from the group consisting of (i) rotation therapy, (ii) deep cell bladder therapy, (iii) vibration/percussion therapy or (iv) alternating cushion therapy; a first pump that directs a fluid into and/or out of the first fluid bladder system at (a) a maximum inflate mode so the first fluid bladder system entire top surface is in the same plane and/or above the crib's top surface, (b) a normal inflate mode to provide patient support and so at least a portion of the first fluid bladder system top surface is below the crib's top surface to allow the crib to function as a restraint, and (c) a bottoming out mode so the first fluid bladder system provides little to no patient support and forms an exterior cavity; and a removable second cushion that provides a second cushion therapy that is different from the first cushion therapy, and positioned (a) in the exterior cavity so the removable second cushion's top surface is positioned below the crib's top surface for the crib to remain a restraint for the mattress system and (b) over the first fluid bladder when the first fluid bladder system is deflated or in the process of being deflated.
