Abstract: A dual-purpose mechanics creeper includes: a flat board, a first swing arm and a second swing arm pivotally attached to a bottom surface of the flat board. Each swing arm includes a plurality of rollers. When each swing arm is at the first position, it is adjacent to the bottom surface of the flat board. When the swing arm is at the second position, it is perpendicular to the flat board. When the second swing arm is at the second position, it is attached to the first swing arm, such that the second swing arm is obliquely supported between the flat board and the first swing arm.

Abstract: A work chair includes a base frame including a transverse portion, a longitudinal portion vertically located on the transverse portion and a plurality of rollers provided at a bottom side thereof, a first pivoting frame pivotally connected to the transverse portion and biasable between a horizontal position and a vertical position, a second pivoting frame including a bottom support portion and a top support portion. The top support portion has one end thereof pivotally connected to the longitudinal portion of the base frame such that the second pivoting frame can be biased to move the top support portion from a vertical position to a horizontal position where the second pivoting frame is placed across the first pivoting frame.
