The Wrist Rest You Own Is Probably in the Wrong Place — Korean and US Safety Agencies Agree on Where It Belongs

Wrist rests have become standard equipment at computer workstations, yet they are routinely misused. Guidance from South Korea's occupational safety authority makes clear that with these accessories, placement is everything.

According to recommendations from the Korea Occupational Safety and Health Agency (KOSHA), a wrist rest should primarily support the area beneath the heel of the hand and must never press directly on the sensitive wrist. While actively typing, the hands need to move freely over the keys, and the wrist should stay in as straight a line as possible with the forearm.

Matching height and tilt to the keyboard

KOSHA's guidance requires hand and wrist supports to be designed so they never obstruct typing at any point. That presupposes the accessory's height and tilt are matched precisely to the design of the keyboard in use.

If the rest sits too high or too low, the wrist bends during work, which can cause strain. To achieve an ergonomically neutral posture, employees should always adjust keyboard and chair height together with the rest.

The US Occupational Safety and Health Administration (US-OSHA) offers similar advice. It likewise stresses that hands must remain free to move while typing and that the rest should serve only as support for the heel of the hand during pauses.

Constant pressure on the wrist, the agency notes, restricts the natural range of motion. With mouse pads that have a built-in elevation, users should make sure the joint is not locked in place during cursor movements.

US-OSHA further recommends avoiding hard desk edges, placing rests flush with the front edge of the keyboard, and correcting working height immediately at any sign of wrist bending. Elbows should stay close to the body and shoulders relaxed.

Lab testing and tuning the whole workstation

How much precise alignment of input devices matters is also reflected in the testing procedures of peripheral manufacturers. Logitech examines ergonomic devices at its in-house Ergo Lab in Switzerland, using pressure sensors and continuous posture monitoring.

The measurements record how heavily the six muscles most active during typing and cursor movement are engaged, while the angles of the neck and arms are checked at the same time. According to the company, design modifications must not negatively affect either working speed or precision.

Individual models, among them the Wave Keys keyboard with its wavy key layout and integrated wrist rest and the vertical ERGO Lift mouse with a 57-degree angle, have received certifications from the specialist organisation United States Ergonomics.

As basic conditions for a workstation, the company recommends placing the top edge of the screen at eye level, holding the arms at a 90-degree angle and ensuring the feet are firmly planted on the floor.

The market for separate accessories offers differing approaches in material and construction. Manufacturer Faluber, for instance, sells a keyboard rest made of walnut wood that measures 440 millimetres (17.3 inches) in length, 80 millimetres (3.2 inches) in depth and 20 millimetres (0.8 inches) in thickness, with an edge angled at 5 degrees.

Keychron added a split silicone palm rest to its range on 28 August 2026. Whatever the material, what counts for occupational safety is that the chosen model supports a neutral alignment of hand and forearm.
