The Stanley Utility Mat [$49.97] is made with superior ³Comfort Made Tough² technology which was engineered with an optimal balance of cushion, support and durability proven to relieve pressure and soreness on feet, knees and back (giving you more time and energy to complete your home improvement projects!) Stanley Utility Mat features premium polyurethane construction engineered specifically to stand up to a rugged workshop environment and is resistant to chemical spills. Backed by a 20-year warranty. I have one in my garage in front of my work bench and it is great! I used to have a sore back after a few minutes of standing on that concrete floor, but when standing on the Stanley Utility Mat I feel great, even after several hours. This is a must have.
