An armrest for a captain's chair of a vehicle includes an outer layer and an inner layer including a foaming agent and defining a hollow core. At least one of the inner layer and the outer layer may include a reinforcing material and/or may be varied in thickness along its length. The armrest may include a third layer defining the hollow core. A related method includes heating a parison having a first and second layers, mixing a foaming agent into the second layer prior to heating, feeding the heated parison between mold halves, clamping the heated parison by moving the mold halves together, and pushing the layers of the heated parison outward, using blown air, such that the first layer is adjacent the mold and the second layer forms a hollow core of the armrest, the hollow core being partially filled by expansion of the second layer during cooling.
