The water columns are of maximum cross-sectional area adjacent the top surface of the mattress and of minimal cross-sectional area adjacent the bottom surface of the mattress. The intervening ventilation chambers are open to the atmosphere and are of minimal cross-sectional area adjacent the top surface of the mattress.
