More Comfort While you Work Wrenching on your vehicle of choice doesn't always put in the most comfortable position in the world, but then you factor in hot pavement, spilled fluids, and whatever else into the mix and that tune up or part you're putting on turns into a nightmare. The BedRug TrackMat is here to help. Measure two feet wide and four feet long, the BedRug TrackMat provides a comfortable place for your knees or back while you take care of business with your vehicle of choice. The BedRug TrackMat is made out of a similar material as life jackets and is resistant to moisture, oil, dirt, and other grime while still providing you a comfortable platform for getting the job done. This 3/4" foam mat folds in half for easy storage and is 100% recyclable.
