A cushion assembly has a main body comprising a plurality of walls defining an interior cavity that is substantially polygonal in cross-section. At least one of the walls comprises an area of padding. A first opening to the cavity is located at a first end of the main body. A blanket is housed within the cavity and is removable from the main body. The cavity is adapted to house a vehicle armrest when the blanket is removed therefrom such that at least an upper surface of the armrest is at least partly covered by a wall having an area of padding.
