Mechanic's creeper seat
Dale Adams Enterprises
Dale Adams introduces the Tail Bone. Like their line of Bone line creepers, it’s the only 100% American creeper seat currently on the market. Pop the seat on, attach the casters, and have a roll on it. They’re made out of a special polypropylene blend that’s resistant to nearly all chemicals, oils and solvents. The wheels are covered by a lifetime warranty as well.
