Those pads really do make the difference on this 71 year old body. Especially when I stack them, is very soft to lay on and way easier to scoot out from under vehicle. In the pic, I also use the two smaller pads to kneel down on to save my knees. The other advantage is that they handle fluid spills/stains easily and can set jack stands on them and use floor jack on top of them. My girl is the one who saw these and got them for me. She takes care of me, way better than I do. She worries about me being under these vehicles and will climb under with me and also hang around topside and hand me tools and rags and drain pans and and and, so I don't have to crawl out all the time. She actually gives me the "hard look" if I go under a vehicle without her being there. I got so lucky with her. Grew up helping her dad in the garage and around family vehicles and loves football and NASCAR.
