A combination adaptive energy absorption and emergency flotation device for positioning beneath a plurality of seat pans of a seat assembly in an aircraft seating application. The device includes a plurality of fluidly coupled inflatable elastic bladders, at least one constrictor valve fluidly coupling at least two adjacent ones of the plurality of inflatable elastic bladders allowing fluid flow therethrough in response to predetermined pressure on the device from the plurality of seat pans, and a fluid supply source fluidly coupled to the plurality of inflatable elastic bladders for outputting a positive flow of fluid to the plurality of inflatable elastic bladders, wherein the adaptive energy absorption device is detached from the plurality of seat pans to allow removal from beneath the plurality of seat pans for use as an emergency flotation device.
