Other ergonomic products are used to prevent and reduce the pain of
repetitive stress-induced injuries. Monitor lifts, wrist pads,
armrests, mouse pads, ergonomic mice, keyboards, and keyboard trays
allow a worker to personalize the comfort and placement of their arm
position at their workspace. Footrests and anti-fatigue mats position
the lower limbs, which can have a drastic affect on lower back
comfort.

Ergonomic products are specialized for use in particular industries,
such as products for cashiers in retail settings, or safety footwear
and impact reduction footwear for warehouse and hospital workers. A
quick Web search will show a host of companies selling ergonomic
products, with most catering to office environments. Kitchen products,
such as knives with handles that mold to the grip, are also popular.
