What anti-fatigue mat should I use with a standing desk?

An anti-fatigue mat is strongly recommended for standing desk use. Anti-fatigue mats with 3/4"–1" thickness and a firm foam or gel core provide the best cushioning-to-stability ratio. Active mats with terrain features reduce fatigue further. Mats should be at least 20"x32". FindOfficeFurniture.com carries anti-fatigue mats for standing desks — call 888-719-4960.
