I have been using an old seat cushion out of an old tent trailer to lay on while I'm under my truck. It had great foam, perfect size 2x4', had nice dark brown tough fabric to camouflage the grime. Well, needless to say after a couple years of work, welding and naps she was in very rough condition. A couple times I caught it on fire 😳.
Not anymore! I was given a large roll of excess fire blanket material from my brother and proceeded to rewrap my old cushion.
It is so awesome to nap...I mean work comfortably under the old 1 ton again.
