A locking pin and pull ring convert this frame in seconds: flat it is a 40 by 17 by 5.5 inch creeper for under-car work, upright it becomes a 20 by 17 by 17 inch Z-shaped stool for brake jobs and wheel swaps. The tubular metal frame uses a reinforced triangular brace, rated for 330 pounds in creeper mode and 265 pounds as a seat. Padding runs faux leather over EPE foam with an engineered wood core, spread across the head and torso sections. Six 360 degree casters carry it over concrete and shop floors, and the 4 inch low-profile deck height slides beneath most vehicles. At 12 pounds the whole unit hangs on a pegboard hook, so the same tool covers rolling under a chassis and sitting beside it.
