What types of armrests do office chairs have?

Office chair armrests range from fixed to 4D (height + pivot + forward/back + rotation). For most office users, height-adjustable (1D) or 2D armrests are sufficient. For intensive keyboard and mouse users, 4D armrests allow the most natural wrist positioning. FindOfficeFurniture.com product specs specify armrest type and adjustment range — call 888-719-4960.
