  "textContent": "An upholstery is described. The upholstery includes a dress cover (204) which covers a cushion (202). Artificial muscles are incorporated into the dress cover (204). The artificial muscles improve the pressure distribution between a passenger and the cushion (202). The artificial muscles are yarns which change length in response to receiving a voltage differential. The change in length of the yarns causes the dress cover (204) to bulge. The bulge of the dress cover (204) then allows the cushion (202) to expand thereby changing the stiffness of the cushion (202). The voltage differential across the yarns is adjusted to accommodate passengers with a range of weights. The upholstery is applied across an aircraft cabin in seat pans, seat backs, head rests, and leg rests.",
