For additional support of the head and/or neck, various head and neck cushions are available. Some of them are illustrated here.
Head and neck cushion no. 1 is a slightly larger head cushion with a pre-shaped filling. This cushion is particularly comfortable in the relax and rest positions. When this cushion is filled with loose filling, it is called pillow no. 6.
