A vehicle seat includes a cushion having a coverstock defining a seat surface with a flexible central region and a flexible edge region. The vehicle seat further includes a compressible edge bladder beneath the coverstock edge region and a first compressible inflation bladder positioned beneath the coverstock central region and in fluidic communication with the edge bladder. A first fixed quantity of a flowable medium is contained in and partially transferrable between the edge bladder and the inflation bladder.

1. A vehicle seat, comprising: a cushion including: a coverstock defining a seat surface with a flexible central region and a flexible edge region;a compressible edge bladder beneath the coverstock edge region;a first compressible inflation bladder positioned beneath the coverstock central region;a first flexible tube directly fluidically coupling the edge bladder with the first inflation bladder in a first closed unit having a first maximum inflation pressure; anda first fixed quantity of a flowable medium contained in the first closed unit at a pressure of less than two-thirds the maximum inflation pressure. 2. The vehicle seat of claim 1, wherein: the flexible edge region of the coverstock is moveable between a compressed position and an elevated position; andthe edge bladder is compressible to permit movement of the edge region into the compressed position. 3. The vehicle seat of claim 2, wherein the edge bladder is compressible by transfer of at least a portion of the first fixed quantity of the flowable medium from the edge bladder to the inflation bladder. 4. The vehicle seat of claim 2, wherein the edge bladder is inflatable by transfer of at least a portion of the first fixed quantity of the flowable medium from the inflation bladder to the edge bladder to provide a retention force to retain the edge region in the elevated position. 5. The vehicle seat of claim 1, further including a seatback rotatably coupled with the cushion. 6. The vehicle seat of claim 5, wherein: the seatback is moveable with respect to the cushion, by being rotatably coupled therewith, between an open position and a closed position, the upper region of the seatback being positioned away from the edge region of the cushion when the seatback is in the open position, and a portion of the seatback being in contact with the edge region when the seatback is in the closed position; andwhen in the closed position, the contact between the edge region and the seatback compresses the edge, thereby transferring a portion of the first fixed quantity of the flowable medium from the edge bladder to the inflation bladder. 7. The vehicle seat of claim 1, wherein the cushion further includes a second compressible inflation bladder positioned beneath the coverstock central region, the vehicle seat further including: a seatback rotatably coupled with the cushion and defining a flexible upper region and including a compressible upper bladder underlying the upper region and in fluidic communication with the second inflation bladder;a second flexible tube directly fluidically coupling the upper bladder with the second inflation bladder in a second closed unit having a second maximum inflation pressure; anda second fixed quantity of the flowable medium contained in the second closed unit at a pressure of less than two-thirds the maximum inflation pressure. 8. The vehicle seat of claim 7, wherein the cushion further includes: a third compressible inflation bladder positioned beneath the coverstock central region; and;a third flexible tube directly fluidically coupling the edge bladder with the second inflation bladder such that the third inflation bladder is included in the first closed unit;wherein the first and third compressible inflation bladders positioned on opposing sides of the second inflation bladder. 9. A vehicle seat cushion, comprising: a coverstock defining a seat surface with a flexible central region and a flexible edge region;a compressible edge bladder beneath the coverstock edge region;a compressible inflation bladder beneath the coverstock central region and in fluidic communication with the edge bladder;a flexible tube directly fluidically coupling the edge bladder with the inflation bladder in a closed unit having a maximum inflation pressure; anda fixed quantity of a flowable medium contained in the closed unit at a pressure of less than two-thirds the maximum inflation pressure. 10. The seat cushion of claim 9, wherein: the inflation bladder is compressible from a neutral state to a compressed state; andwhen the inflation bladder is in the neutral state, the coverstock edge region is compressible from an elevated position to a compressed position by compression of the edge bladder causing at least partial transfer of the fixed quantity of flowable medium from the edge bladder to the inflation bladder. 11. The seat cushion of claim 10, wherein when the inflation bladder is in the compressed state, at least a portion of the fixed quantity of flowable medium flows from the inflation bladder to the edge bladder, thereby providing a supporting force within the edge bladder to maintain the edge region of the coverstock in the elevated position. 12. The seat cushion of claim 9, wherein the inflation bladder and the edge bladder are fluidically coupled by a tube in fluidic communication with the edge bladder at a first end thereof and the inflation bladder at a second end thereof. 13. A vehicle seat, comprising: a cushion including an edge bladder within an edge region thereof and an inflation bladder within the cushion remote from the edge region, a flexible tube directly fluidically coupling the edge bladder with the inflation bladder;a seatback rotatably coupled with the cushion and including an upper bladder within an upper region thereof; anda second flexible tube directly fluidically coupling the upper bladder with the inflation bladder;wherein the inflation bladder, the edge bladder, the upper bladder, and the first and second tubes define a closed unit having a maximum inflation pressure and containing a fixed quantity of a flowable medium at a pressure of less than two-thirds the maximum inflation pressure. 14. The vehicle seat of claim 13, wherein the fixed quantity of the flowable medium is partially transferrable between the inflation bladder and the edge bladder and between the inflation bladder and the upper bladder. 15. The vehicle seat of claim 13, wherein: the inflation bladder is compressible from a neutral state to a compressed state; andwhen the inflation bladder is in the neutral state, the edge region of the cushion is compressible from an elevated position to a compressed position by compression of the edge bladder causing at least partial transfer of the fixed quantity of the flowable medium from the edge bladder to the inflation bladder. 16. The vehicle seat of claim 15, wherein when the inflation bladder is in the neutral state, the upper region of the seatback is compressible from an extended position to an inward position by compression of the upper bladder causing at least partial transfer of the fixed quantity of the flowable medium from the edge bladder to the inflation bladder. 17. The vehicle seat of claim 15, wherein when the inflation bladder is in the compressed state: a first portion of the fixed quantity of the flowable medium flows from the inflation bladder to the edge bladder to support the edge region in the elevated position; anda second portion of the fixed quantity of the flowable medium flows from the inflation bladder to the upper bladder to support the upper region in the extended position. 18. The vehicle seat of claim 13, wherein: the seatback is moveable with respect to the cushion, by being rotatably coupled therewith, between an open position and a closed position, the upper region of the seatback being positioned away from the edge region of the cushion when the seatback is in the open position, and the upper region being in contact with the edge region when the seatback is in the closed position; andwhen in the closed position, the contact between the edge region and the upper region compresses the edge bladder and the upper bladder, thereby transferring portions of the fixed quantity of the flowable medium respectively from the upper bladder and the edge bladder to the inflation bladder.
