It's cold outside and probably cold inside on those concrete floors in your plant or warehouse.  Now's the time to improve your worker's comfort by adding Ortho Mat ergonomic mats at their workstations.  Ortho Mat will not only reduce fatigue but will also keep their feet off of those cold surfaces which will reduce cramping associated with standing on cold hard surfaces for extended periods of time.  Ortho Mat safety mats from Indoff, your warehouse specialist.
