What types of armrests do office chairs have?

Office chair armrests range from fixed (non-adjustable, set at one height) to 1D (height-adjustable only), 2D (height and width), 3D (height, width, and pivot angle), and 4D (height, width, depth, and pivot). Fixed armrests are rarely ergonomically ideal since they can't be set to the right height for each user. At minimum, look for 2D armrests for any shared workstation chair; 3D or 4D arms are worth the upgrade for primary task chairs used 8+ hours daily. Soft polyurethane armrest pads are more comfortable and longer-lasting than hard plastic. FindOfficeFurniture.com has office chairs with all armrest types — call 888-719-4960.
