An aircraft seat comprising a seating surface, an armrest comprising an armrest surface, and a gas strut, wherein the gas strut is coupled at a first end of the gas strut to the armrest and is coupled at a second end of the gas strut to a substructure of the aircraft seat such that the armrest can be moved between a raised position with respect to the seating surface and a lowered position in which the armrest surface is substantially level with the seating surface by extending and retracting the stroke of the gas strut, and wherein the gas strut comprises a switch with an unlocked configuration in which the stroke of the gas strut can be adjusted, thereby allowing movement of the armrest to any position between the raised position and lowered position, and with a locked configuration for locking the stroke of the gas strut so that the armrest can be held at any position between the raised position and the lowered position, and wherein the aircraft seat further comprises a mechanical linkage comprising an actuatable member located on a surface of the aircraft seat, a trigger configured to move the switch between the locked configuration and the unlocked configuration, and an elongate tension member that is coupled to and runs along an underside of the armrest surface, the tension member being coupled at a first end to the actuatable member, and coupled at a second end to the trigger such that actuation of the actuatable member exerts a tensile force on the tension member and causes the tension member to pull the trigger into engagement with the gas strut switch to move the gas strut switch from the locked configuration to the unlocked configuration. wherein the gas strut is coupled at a first end of the gas strut to the armrest and is coupled at a second end of the gas strut to a substructure of the aircraft seat such that the armrest can be moved between a raised position with respect to the seating surface and a lowered position in which the armrest surface is substantially level with the seating surface by extending and retracting the stroke of the gas strut, and wherein the gas strut comprises a switch with an unlocked configuration in which the stroke of the gas strut can be adjusted, thereby allowing movement of the armrest to any position between the raised position and lowered position, and with a locked configuration for locking the stroke of the gas strut so that the armrest can be held at any position between the raised position and the lowered position, and wherein the aircraft seat further comprises a mechanical linkage comprising an actuatable member located on a surface of the aircraft seat, a trigger configured to move the switch between the locked configuration and the unlocked configuration, and an elongate tension member that is coupled to and runs along an underside of the armrest surface, the tension member being coupled at a first end to the actuatable member, and coupled at a second end to the trigger such that actuation of the actuatable member exerts a tensile force on the tension member and causes the tension member to pull the trigger into engagement with the gas strut switch to move the gas strut switch from the locked configuration to the unlocked configuration.
