Blast energy attenuating recoverable seat insert

A seating system for a vehicle, comprising:

• a frame configured to be coupled to a chassis of the vehicle;
• a seat cushion supported by at least one of the frame and a floor of the vehicle;
• a first recoverable insert configured to provide a first energy attenuation response;
• and
• a second recoverable insert configured to provide a second energy attenuation response different than the first energy attenuation response,
• wherein the seat cushion defines a cavity shaped to interchangeably receive either the first recoverable insert or the second recoverable insert to thereby selectively vary an energy attenuation provided by the seating system and wherein the frame defines an aperture and the second recoverable insert defines a passage that corresponds with the aperture, the aperture and the passage defining a flow path that places the second recoverable insert in fluid communication with an interior volume of the vehicle.
