Its a must have for anyone who has to work on any truck engine bay. Makes working on a truck for long hours a breeze, i have used it for awhile now and i love it no more pain in my back and sides from laying on the engine. It also folds down and away so it doesn't take up much space in my shop. For years i worked in discomfort on my 2001 ford f250, after a few minutes working over a warm engine bay my shirt would be soaked with sweat. I finnaly broke down and bought one, im so glad i did, well wSee full review
