1. An air supply comprising:
an air compressing device;
a first pressure valve; and
a second pressure valve;
wherein the air supply is operable to continuously introduce air from the first pressure valve to a first inflatable device at a first pressure within a first air pressure range to maintain a generally consistent internal pressure while the first inflatable device releases air therefrom, and, on demand, to introduce air from the second pressure valve to a second inflatable device at a second pressure within a second air pressure range while continuing to supply air to the first inflatable device at a pressure within the first air pressure range, the second pressure being different from the first pressure, the air compressing device comprising a first compressor and a second compressor each contained within a housing, the first compressor fluidically coupled to the first pressure valve and the second compressor fluidically coupled to the second pressure valve.
