An armrest assembly may include a base member, an armrest member, a mechanism and a biasing member. The armrest member may be linearly movable relative to the base member between a first position and a second position. The mechanism may be associated with the armrest member and may be movable between an engaged configuration restricting linear movement of the armrest member relative to the base member and a disengaged configuration allowing linear movement of the armrest member relative to the base member. The biasing member may bias the armrest member in a linear direction from the second position toward the first position.
