In order to accurately and quickly monitor the tilt of a mattress, transmitting and receiving coils are provided on opposite sides of an assembly of lifting bladders for the side of the mattress being lifted, and the signal strength is measured when a signal is transmitted therebetween, and the angle of tilt is determined therefrom. In order to reduce exposure of lines leading to an inflatable mattress, a notch is provided in a crib for receiving a pump for pressurizing a cushion within the crib so that the pump is positioned to face exteriorly of the crib to allow heat dissipation.
