Floortex's Advantagemat's help make your desk workspace more ergonomic, by taking the strain off of your legs and back, this is done by providing an easy-glide surface. The key reason chair users purchase floor mats is to protect a small or large area of flooring from indentations and scuffs caused by rolling office chairs, along with dirt and spills, therefore extending the life of your surface. For a more heavy-duty chair mat, Floortex offers a polycarbonate and glass option.
