You wouldn't find many industrial settings that didn't advocate the use of anti-fatigue mats. The opposite is true for most home shops, however. Why? Our best guess is most woodworkers are a hardy bunch (that and they probably don't like having to buy a mat that may or may not be the right size for their existing space). Here's the answer. This extra-thick mat comes in 3 ft. by 3 ft. squares so you can customize it to your space and it's 5/8" thick for comfort. Give your feet a reason to be as happy as your hands are while you're working on your project (and stay on the job longer as well)! Drainage holes are 1" dia. Imported.
