Abstract: A compact body support apparatus is provided for use with an armrest of a vehicle such as an airplane, train, or bus. The compact body support apparatus comprises a base, a support post, a housing, and a headrest cushion. The support post presents a lower end secured to the base and an upper end. The housing is secured to the upper end of the support post. The headrest cushion is secured to the housing for supporting a head of a user. The compact body support apparatus is configured to be selectively placed into a collapsed position and a deployed position, such that the support post and at least a portion of the base are disposed within the housing when the compact body support apparatus is in the collapsed position and the support post extends in a generally downward direction when the compact body support apparatus is in the deployed position.
