A great way to show people who make decisions about seating for your office and facility how many absolutely useless chairs there are in the market. If you need to be certain about your decision ask one of the local ergonomic firms (and make sure they are certified ergonomic experts not OT, PT or Kins) to review seating products for your firm and to narrow the selection down based on ergonomic criterion. We can guide you on this process so feel free at Info@OptimalPerformance.ca
