The must have accessory for anti fatigue mats that slip on rough floor surfaces.
If you stand on floors that aren't sealed or smooth, you may want to invest in the GellyGrippers ™ .
GellyGrippers are double sided non-slip gel pads designed to create a serious stay put grip on many floor types, including wood, tile, laminate, or linoleum.
They are sticky, yet won't leave any sort of sticky residue behind and won't harm floors.
If the grippers become dirty or dusty, simply wash them clean in water to renew the sticky grip.
