A status statement for the mainstream specialist, the Deflecto RollaMat offers superior performance. The studded design secures the mat, preventing it from moving while protecting the carpet from caster wear, spills and heavy traffic. This is a medium weight chair mat for frequent use on carpets up to 1/2" thick. A smooth beveled edge makes for easy carpet to mat transition. The free and Clear® non-ortho-phthalate, non-cadmium formula promotes a healthy work environment while offering exceptional clarity and durability.
