Change the look of your mat—without losing any of the comfort! Decorative mat inserts slip securely inside the anti-fatigue mat tray for an instant update. The Comfort Tray™ is made from thick, stress-relieving PVC foam that helps take the pressure off of back, legs and knees. Decorative mat inserts are permanently dyed with state-of-the-art printing for long-lasting wear. Made with recycled non-skid rubber backing, they can be used solo but provide you with all the comfort when used inside the non-slip tray. Mat inserts are printed in the USA.
