Abstract: An infant care apparatus such as an incubator or infant warmer having a mattress for supporting the infant on an infant platform that can, at times, by fully rotated 360 degrees to obtain full access to the infant. In the incubator, a translation platform can be slid into and out of the infant compartment and the mattress tray is pivoted to that translation platform so as to rotate at a pivot point that connects the mattress tray to the translation platform. Accordingly, when all of the doors of the infant incubator are in the closed position, the mattress tray is constrained from rotational movement but that mattress tray can be rotated a full 360 degrees whenever both doors are open or when the translation platform has been moved to a position at least partially exterior of the infant compartment. In all, the apparatus provides easy and convenient access to the infant for carrying out procedures on the infant while it is still supported by the infant care apparatus.
