The body support board provides a comfortable work surface for a user to lay on while working. In a non-limiting exemplary embodiment, the body support board preferably includes an elongated board member, padded section(s), a head cushion, at least one light member, at least one removeable tool case, at least one light switch, and an adjustable support leg or stand.
