This versatile desk mat effectively “reduces" your weight by 30% to make standing easier on your feet and joints. The advanced multi-layer construction offers a comfortable “leather like" top surface, a memory foam inner layer and a non-slip bottom. A perfect 30" x 20" size provides plenty of room to move around, but still can fit into the kneehole of a standard desk or built-in when it is not being used. Beveled edges help to reduce tripping issues and ¾" commercial grade thickness provides hours of comfort and stability. The durable materials on this desk mat will not break down, even after years of use.
