What type of flooring is best under an L-shaped desk?

Flooring specification matters for workstation deployment. On carpet, we recommend hard-floor rollerblade casters (clear urethane wheels) on office chairs and a PVC chair mat (minimum 36"x48", 0.125" thickness) to protect carpet pile and enable easy rolling. On hard floors, polyurethane casters protect both the floor and the chair mechanism. At OfficeFurniture2go.com, we specify appropriate casters and mats as part of every workstation order.
