A pressure control system for an aircraft seat includes a base plate and a plurality of cells attached to the base plate, each cell having a bellows and a top inflatable diaphragm and defines a pressure chamber therein. Charging apertures are formed in the base plate such that each cell has an associated charging aperture such that each charging aperture is in fluid communication with a pressure chamber. Discharging apertures are formed in the base plate such that each cell has an associated discharging aperture such that each discharging apertures is in fluid communication a pressure chamber. A charging valve and a discharging valve is in fluid communication with the pressure chambers and configured to supply or extract air to or from the chambers through the apertures. A pump is configured to supply pressurized air to the at least one charging valve.
