Advice for Good Office Ergonomics

ByEmily Dolloff

Let’s look at how to keep your body comfortable and healthy when you interact physically with your Mac. In a word: ergonomics. You’ll find it easier to focus and be productive if nothing hurts. Plus, you want to avoid long-term problems like carpal tunnel syndrome and chronic neck strain.

While some workplace setups may be outside your control, there are usually ways to improve your ergonomics. Here’s what to check and adjust to make your workspace more comfortable and productive. We also recommend working through the Cornell Ergonomic Workstation Advisor, a 35-question worksheet.

Chair Setup

Your chair is the linchpin of an ergonomic office setup. Adjust the seat height so your feet rest flat on the floor and your knees are at roughly 90º–120º. Use a stable footrest if you can’t put your feet flat on the ground without compressing your thighs. Note that if you are smaller or larger than average, you may need a chair designed for your size.

You should be able to sit up straight comfortably, which may be aided by a lower back support. If your chair lacks one, consider adding a firm bolster or even a rolled towel for more support. Make sure armrests support your elbows without forcing you to raise your shoulders.

Once your chair is adjusted correctly, it’s time to consider the desk surface, which affects the placement of your display, keyboard, and mouse or trackpad.

Screen Position and Height

When it comes to your Mac’s display, there are two vital measurements to reduce neck and shoulder strain: the distance from your eyes and the height off the desk surface.

Roughly speaking, the display should be positioned at arm’s length, or 18–36 inches (45–91 cm) away. However, that depends on your vision—if the text isn’t clear at the recommended distance, you should either have your prescription checked or move the display until you can read it easily. If you find yourself bringing it too close, use the Larger Text options in System Settings > Displays to make the text readable at a reasonable distance.

For height, with modern large displays, aim to have your eye level about a quarter of the way down the display, so that three-quarters of the display is below your eye level. That generates a slight downward gaze to the center of the screen. If you wear bifocals, position the display a little lower to account for how you raise your head to look through the different viewing zones in your lenses.

Some displays have highly configurable stands, making it easy to adjust their height. For those that offer only tilt adjustments, you can raise the screen by placing a properly sized book or printer paper underneath it; just make sure it’s stable. If your desk doesn’t lend itself to the necessary positioning, a monitor arm could make it easier to adjust.

It’s important to minimize glare from lights above you or windows behind you. Tilting the top of the display slightly away from you can reduce glare and enhance comfort, but more significant adjustments may be necessary to avoid harsh natural light. If you need bright light for reading physical documents, opt for task lighting and keep the room lighting indirect. Regardless, you should always adjust the Mac’s brightness to match the room lighting; the Automatically Adjust Brightness switch in System Settings > Displays can help. If you use your Mac before bed, turning on Night Shift may improve sleep.

What about multiple displays? Depending on their size, you may inadvertently create a situation where the text is too far away to read comfortably, causing you to lean in. Nor do you want to be working with your head turned all the time.

If you have a primary display, position it in front of you and put the secondary display off to the side, angled in. If you have two identical displays, angle them in slightly to create a visual arc and sit so that you can work comfortably on the inner halves of each screen. Those connecting a laptop to two displays can keep it below them. However you arrange your displays, click Arrange in System Settings > Displays to rearrange the virtual screens so they match your physical layout.

Keyboard and Mouse/Trackpad Placement

For comfortable typing and mousing, your hands should be level and straight, with your elbows comfortably close to your body and your shoulders relaxed. To make that happen, the keyboard and pointing device should be at elbow height when you’re sitting and close enough that you don’t need to lean forward. The mouse or trackpad should be as close to the keyboard as possible so you don’t have to reach for it.

Getting the height of the keyboard and pointing device right—while also keeping the display at the right height—can be tricky because many desks aren’t very adjustable. If the desk is too high and can’t be lowered, consider an adjustable keyboard tray to reposition the keyboard and mouse/trackpad at the correct height.

It’s also important that you don’t compress your wrist by pressing down on the desk surface or even a soft wrist rest. To rest your hands when you’re not typing, use a cushioned palm rest in front of your keyboard.

Special Considerations for Laptops

Unfortunately, it’s impossible to maintain good ergonomics on a laptop because there’s no separation between the keyboard and the display. That’s fine for shorter work sessions and when you have no control over your environment, such as on an airplane or in a coffee shop. But if you work on a laptop all day long, choose one of two basic options to improve your ergonomics:

  • Continue to use the laptop’s keyboard and trackpad at a good typing height, but add an external display at the ergonomic viewing height. You can continue to use the laptop’s display for ambient apps—such as Messages, Calendar, and Music—that you glance at and use briefly.
  • Elevate the laptop so its display is at the correct viewing height, and add an external keyboard and mouse/trackpad at the correct typing height. A wide variety of laptop stands are available for this purpose.

The first approach may be more expensive, but it can increase productivity by allowing you to view more content on the screen at once.

Movement and Breaks

No matter how ergonomic your setup is, it’s terrible for the human body to remain in one position for extended periods. Research suggests that sitting for more than 8 hours daily, especially without physical activity, is associated with cardiovascular disease, diabetes, obesity, cancer, depression, and even cognitive decline. Luckily, it’s easy to reduce these risks:

  • Change positions frequently; chairs that allow movement can help activate muscles and improve circulation.
  • Take regular breaks every 30–60 minutes. Standing or walking for 5 minutes is ideal, but even a minute or two helps. Even if you work at a standing desk, you must still move around.
  • Consider a sit-stand desk that allows you to switch between sitting and standing.
  • Look away from your screen at least every 20 minutes for 20 seconds, focusing on an object at least 20 feet away.
  • Exercise regularly to counterbalance being sedentary—experts recommend a weekly regimen of 150–300 minutes of moderate exercise or 75–150 minutes of vigorous exercise.

Remember: Small ergonomic adjustments can make a big difference in comfort. If you experience persistent discomfort in an office environment, consult with your supervisor or HR department about your ergonomic equipment options. Your organization may also provide access to an ergonomics expert who can come to your workspace and ensure that your chair and other workspace items are adjusted for optimal comfort.

  • CES Random Thoughts

    I talked a bit about the big Consumer Electronics Show last week and it is rapidly fading in the rearview mirror. I have gone to this show every year for the past decade or more. We actually exhibited our Chill Pill speakers and Hammerhead products at one CES but mostly I have come as a “buyer” to look for new products and trends.

    The Las Vegas convention center is a gigantic venue and the CES show spills out into the parking lot in front but also into some of the surrounding hotels and resorts. The Sands convention center was the second largest and housed some of the more interesting booths. This was the location for 3D printing, health care, fitness, home automation, robots and drones. There were sophisticated baby monitors, constant reporting thermometers, implanted blood glucose monitors and even a company that sold wireless sensors that monitor your soil’s nutrients and moisture. Home automation was huge with several competing standards vying to challenge Apple’s HomeKit. This year more companies were showing HomeKit compatible products so I think that Apple’s vision of your interconnected home is not far off.

    There are lots of ways to move from the Sands over to the LVCC but the best way is the free buses offered by CES. Cabs and the monorail are possible but the buses seem to be the fastest and they are free and comfortable. For me it was a great way to rest my weary feet for a few minutes before going to the other venue to continue walking through the crowds. At the convention center there are three main halls and the international pavilion over at the Westgate (formerly, Hilton). The Center hall is dominated by the big guys with gigantic booths for Samsung, Intel, LG and others. Those booths are usually mobbed so I quickly walked through to check out the TVs and moved on. The North Hall is where the iLounge was born and products for iPad and iPhone dominate that section. The biggest part of the North Hall, however, was the Auto section with concept cars being shown my several manufacturers including Ford, Audi, Mercedes and new electric car upstart Faraday.

    In the past several years the iLounge area and the international area were dominated by all sorts of cases for iPhones and iPads. This year there were a few in each section but cases were definitely not the dominate category. Over at the international pavilion there were lots of hover boards but unlike previous years, demos of the scooters were restricted to the booth area. Nevertheless, all sorts of scooters were being shown. I searched for interesting USB-C products and found some hubs that were not quite ready for prime time and a bunch of cables. I did see the USB-C displays that incorporate a hub and that could be the real solution for the office set-up for the USB-C equipped MacBook.

    I never seem to be able to coordinate my meetings by hall. It seems that I’ll have one meeting in the North Hall, the next in the South Hall and then another back at the hotel. I rode the buses a lot and got to see the whole show floor that way.

    I did find some interesting products that we may add to our offerings, and had some great meetings so it was worthwhile to visit this show that is a window on future technology.
