Abstract: A foldable mechanic's creeper that it particularly compact and easy to store includes hinge-connected panel members, each having a panel portion and a peripheral flange portion, the panel members being movable between an open position and a closed position in which the flange portions are in edge-contact for forming a closed container. In the open position, the panel members are rollingly supported on casters for carrying a user in a supine position, the user's head being supported on a padded support that is removably mounted in horizontally spaced relation to one of the panel members. With the panel members in the closed psition, the head support and the casters can be safely enclosed within the container that is formed by the panel members. An extensible mount for the head support serves as a carrying handle for the folded creeper.
