Bertech Anti Fatigue Mats with Ribbed Pattern are designed to reduce the fatigue and lower the risk of injury to feet, knees, and lower back. Research shows the negative impact of standing on hard surfaces for a long time on a worker's health and productivity. These anti fatigue mats pay for themselves through improved productivity and tardiness. They combine the durability of vinyl foam cushion technology with a slip resistant top for safety in the workplace. Anti fatigue mats are moisture and stain resistant that cuts the cleaning and maintenance time. Mats are 5/8 inches thick. RoHS and REACH Compliant. Made in USA.
