Working over an engine bay usually means bending across a fender; this topside creeper puts you on a padded platform instead. Height adjusts across four levels from 42 to 69 inches and the deck tilts through three angles, so the reach matches whatever you are pulling. Unfolded it spans 50 by 42 inches, and the H-shaped base with reinforced triangular bracing holds 400 pounds of operator and tools. The 16.5 by 16 by 2 inch cushion is PU leather over sponge, backed by an oxford fabric panel. Four casters roll it around the bay, two of them locking once you are in position. Folded to 17 by 42 by 54 inches it stands against a wall, and the 52 pound metal frame stays planted on smooth concrete while you lean into a job.
