Who Needs a Creeper When One Has This?

I've never liked creepers. They ALWAYS get stuck in ANY crack! Plus, you lose a couple inches of clearance that you may need. And they always want to roll away when you're trying to pull on a wrench.
I used to use carpet scraps. Now I have a couple vinyl covered foam pads that Jeg's sells. Or sold. I just looked, I can't find them on Jeg's site.
