My wife got me a seemingly nice creeper for my birthday. It's metal framed and says AC Delco on the padding. It has an adjustable head rest. The thing about it is that the handle you use to adjust the head rest interferes with one of the wheels when it's in the flat position, so I always have to drag the wheel around, which is super annoying. Anyone else have one of these annoying creepers? I can't see a way to fix it except by removing the handle and taking away the option of using the adjustable headest (always flat).
