Do I really need a chair mat if my office floor is carpet?

You can use a chair on carpet without a mat, but the difference is noticeable — rolling on medium or thick pile takes real effort and adds low-level fatigue throughout the day. A polycarbonate chair mat provides a smooth rolling surface and takes that friction out of the equation entirely. On low-pile carpet, a mat is helpful but not urgent; on high-pile, it's practically essential. FindOfficeFurniture.com carries chair mats for all floor types — call 888-719-4960 to find the right fit.
