Certified professional ergonomists at Humantech developed the Four Points of Contact model to teach individuals to identify ergonomic issues and empower them to take action to adjust their own workstations. Whether you are using a traditional desk/chair workstation, or working on your laptop at an airport terminal, these four elements should be the focus.

The four elements include: eyes to the source; hands to input devices; feet to the floor; and the body to the chair.

5. Select the Right Equipment

With the vast array of office products, equipment and furniture available today (much of which is labeled “ergonomic”), how do you choose which are most appropriate for the task at hand? Refer to this partial list, outlining key features you’ll need when purchasing common workstation items:

Chair – Should offer pneumatic seat-pan height adjustment, a backrest that tilts backward and forward, backrest tension control and lumbar support.
Adjustable workstation – Should offer height adjustability of work surface and have a large surface with ample room to perform tasks.
Keyboard/keyboard tray – Should lie flat and offer slope adjustability to achieve up to ± 15° slope and have a low profile (approximately 1″ or 30 mm).
Input device – Features should include a long cord for proper placement or wireless, should move easily and be usable by left- and right-handed users.
Monitor – Adjustable brightness and contrast, free from flicker and adjustable tilt.
Monitor arm/stand – Should be height-adjustable 27″ (69 cm) to 34″ (86 cm) above the seat pan and the weight of monitor should match the weight of the stand or arm.
Wrist rest – Should be constructed of compressible or soft material to reduce external pressure on the wrist and offer a non-friction surface.
Headset – Should be digital, rather than analog, and offer a quick-disconnect capability.
Footrest – Needs to be height adjustable from 11″ (28 cm) to 18″ (46 cm).
Task lighting – Should offer 75 to 140-foot candles of adjustable lighting and be asymmetrical to reduce shadows and glare spots.
Laptops – Use an external mouse and keyboard for extended periods of computer use and take regular breaks and change your posture when working for long periods of time.
