With so many different ergonomic chairs on the market today, from Office Star and Jobri to BOSS and ergoCentric chairs, finding the right seating choice for your specific needs can be difficult. Ergonomics are certainly not a one-size-fits-all approach. An ergonomically designed work chair should be able to conform to your height, weight, and body type, and also be appropriate for your line of work and professional environment. A tall and heavyset man will probably need a different ergonomic design than a short and petite woman, just as an IT professional will probably need a different office chair than a laboratory technician. With so many different factors to consider, how does one find the right work chair? The following information should help.
Why are Ergonomics so Important?
Ergonomic design is a multidisciplinary field of science that considers various human factors with the goal of designing furniture, equipment, and tools that complement the human body and mind, ideally resulting in more productive workplaces and happier, healthier workers. The way people sit is a very important part of this. Sitting is not as sedentary of a position as one may assume. When a worker in any given field sits in a chair all day (or for a large chunk of their workday), they are also engaging in activities in that chair, which are all influenced by the way that worker engages with their surroundings – especially their chair. The following video is by Allseating a chair manufacturer that describes the cores needs in building your ergonomic workstation.
What Makes a Suitable Work Chair?
If you’re shopping for ergonomic chairs, the most important human factors to consider are the body dimensions of the individual who will be sitting in each chair. And this means all the body dimensions. An ill-fitting chair might be ideal for someone’s height, but not appropriate for their weight and body type, for example. This can lead to stress and strain, and ultimately injury, which could in turn leave a worker unable to work and an employer in hot water. There are other factors to consider, such as the costs of repairs and maintenance, in addition to the initial costs of purchasing the chairs. Avoiding repetitive stress injuries is worth the investment, but not if the company goes into the red from the costs of owning the chairs. Luckily, many manufacturers make some very affordable models that are also high in quality. The following video is for the ergoCentric Geocentric petite ready chair.
It All Comes Down to Body Type
Make sure to gather information about the heights of employees before purchasing new ergonomic chairs for the whole office. An ideal work chair will be roughly a quarter of the user’s height. While most employees doing similar jobs will probably be comfortable in similar or identical chairs as long as the seat and armrests are adjustable, there will also probably be a few outliers who will have special ergonomic needs and require somewhat different chairs. No one should be punished for being uncommonly short or tall, having a long torso or unusually sized limbs, or being otherwise out of the norm. To avoid repetitive stress injuries and find the ergonomic chairs with the best value, consider body type first.
Home office and workplace ergonomics are incredibly important considerations. While it might not seem like improper posture or sitting the wrong way in front of your computer could damage your health, the fact is that you can suffer some serious injuries over time, as noted by the University of Connecticut. What conditions might you suffer if you don’t practice good posture and ergonomics? Here’s a closer look.
Ergonomic and Posture-Related Health Disorders
All ergonomic and posture-related health disorders are technically musculoskeletal disorders (MSDs). MSDs fall into a broad range of categories and conditions. Depending on the length of time you spend sitting, and just how poor your posture or position is, you might find yourself afflicted by any of the following:
- Carpal Tunnel Syndrome – A condition in which the tendons running through the arms, wrists and hands are inflamed, making most common hand and wrist movements painful
- Tendinitis – A condition in which tendons become inflamed; it generally afflicts the arms and elbows, but can be present in other parts of the body as well
- Bursitis – Swelling and inflammation of the fluid-filled sacs between joints, tendons and muscles. It can afflict virtually any area of the body
- Thoracic Outlet Syndrome – This condition includes a weakened grip, pain in the neck, and often tingling or numbness in the fingers
- Chronic pain in the neck, upper back, lower back, shoulders and arms
Each of these conditions can cause serious discomfort and pain, and they can lead to significant time lost from work as well as medical expenses. In severe cases, some may require surgery to correct. For instance, severe carpal tunnel syndrome cannot be alleviated by using wrist braces alone, but may require surgical intervention to eliminate the problem.
How Do You Avoid These Conditions?
Obviously, avoiding and minimizing the conditions listed above is in the best interests of both the employee and the employer. Thankfully, it’s not that difficult to get around those problems. All it really requires is following the right ergonomic practices within the workplace.
Good workplace ergonomics can vary from one position to another, most of the time workers will need the right office chair, the right desk and the right computer setup to provide good posture and eliminate strain on muscles, joints and tendons. An ergonomic office chair should offer:
- Good neck support, either through a built-in headrest or a high back, which is particularly important for those who spend multiple hours each day seated in the chair
- Good lumbar support to ease the strain and discomfort on the lower back – lumbar support can come in the form or an adjustable position via a lever or through additional lumbar padding
- Armrests should be adjustable and padded to ensure that the worker is comfortable and can position the armrests so there is no strain placed on the shoulders
- Adjustable height so that the employee can adjust the seat’s height to allow them to sit with their feet flat on the floor, rather than angled or above the floor
Proper ergonomics in the workplace can improve the health of workers, save money on medical bills, and reduce lost time and productivity for the employer.
Posture – it’s one of those things that we’ve all heard about, but a surprising many know little of. However, for all that it can be difficult to define without heading to your nearest dictionary, it’s an incredibly important consideration in the workplace, particularly for office workers. Good posture helps prevent the development of serious musculoskeletal disorders, prevents muscle strain and more. What should you know about correct posture, though? Read on to learn more.
One of the most important elements of good posture is spine support. When sitting down, your natural inclination is probably to lean forward and rest your weight on the arms of the chair. That’s wrong, and it will lead to serious lower back pain, as well as strain on the muscles and tendons in the arms (especially if you do that while trying to type).
The right type of spinal support is important. The best option is to invest in a quality office chair with a good back (featuring plenty of lumbar support) that follows the natural curvature of the spine. Make sure your feet sit flat on the floor and don’t hang. You should also have maximum contact between your back and the back of the chair without it affecting your ability to type. If your chair has armrests, they should be positioned so that your arms are even with the top of the desk and there’s no shoulder strain present.
Even if your chair has a built-in headrest, chances are good it’s not going to be used unless you’re leaning back (you’re inactive). That means it’s important you practice good neck posture. Ideally, your neck will be in a neutral position (not forcing it forward, back or to the side). The computer monitor should be just below eye level, so you can look at it while maintaining the right position. Your monitor should also be at least 20 inches from your face (a maximum of about 36 inches).
Position everything in your work area so that you can reach it or see it without having to turn your head. This will help you keep your neck in the proper position and avoid straining muscles.
The Importance of a Quality Office Chair
Part of good posture is having the right support for your body throughout the day. In an office environment, that means having a quality office chair. While good chairs do come with a cost, they’re actually more affordable than what you might think, and they’re certainly cheaper than trying to deal with the consequences of carpal tunnel syndrome or chronic lower back pain. A good chair will help support you throughout the day, and should be a “no-brainer” for any office worker (or office manager buying furniture).
With the information above, it should be easier to understand good posture and put it into effect in your daily life. Invest in a good office chair and protect yourself from serious musculoskeletal disorders.
Chair experts can help you to determine your ergonomic needs. In doing so, they will explain these facts in detail.
Adjustable Height Is the Best Height
Adjustable seating options are an excellent choice, since everyone has their own requirements. Your feet should sit flat on the floor while your back remains straight. A pneumatic adjuster allows you to adjust the height. From 16 to 21 inches from the top of the seat to the floor is a suitable size for most users.
Considering the Backrest
Consider the quality and measurements of the backrest when you shop for office chairs. The backrest should be 13 to 19 inches high and naturally support your spine. It should also give your lower back proper lumbar support.
Determine Seat Depth and Width
Your position in the chair is integral for your spinal health and overall comfort. It will also add to your job satisfaction and workplace productivity. The seat should support you completely when you are sitting. 17-20 inches as a seat width will fit most people.
The materials in the backrest and seat must be comfortable. Standard seat foam will allow most people to sit comfortably all day. If you need soft or firm support, choose chairs with triple density foam or memory foam. Mesh makes for a breathable chair, which is an advantage in a warm climate.
Last but far from least is lumbar support. It is actually the most important part of an ergonomic office chair. Without good lumbar support, you will slouch and this will strain the lower area of your spine. Adjustable chairs will help an office chair to meet your personal ergonomic needs.
In conclusion, if you have doubts about any office chair before you purchase one, consult with an expert before you make that purchase. Then your decision will be an informed one.
Ergonomics – it’s become an immensely important consideration for both individuals and employers. Even UCLA has started offering ergonomics guides and information for students, teachers and others. Whether you’re an office worker or an employer, it’s important that you understand the key concepts in workplace ergonomics in order to prevent injury, maximize productivity and reduce ergonomic injury-related lost time from the job.
Reducing Strain and Stress on Key Body Parts
The entire point of ergonomics is to position office equipment and to support the body in such a way that it reduces strain on key body parts. These include the following:
- Upper and lower back
- Thighs and legs
Key Ergonomic-Related Injuries
33% of all workplace injuries involve musculoskeletal injuries generally caused by poor workplace ergonomics. These injuries cause a significant amount of lost time at work, which impacts both the employer and the employee. Some of the conditions caused by not implementing the correct ergonomic plan can include carpal tunnel, eye strain/headaches, tendinopathy, bursitis and many others.
Key Concepts to Understand
There are several different concepts at play in workplace ergonomics, including posture, correct workstation setup and more. These include the following:
- Neutral Neck Position – Your workstation, desk and office chair should allow you to maintain a neutral neck position. A computer monitor should be at least 20 inches away from your body, and it should be directly in front of and slightly below your eye level.
- Spine Support – Sitting for long hours puts serious stress on your spine and back/shoulder muscles. To correctly support your spine, you need to sit with your feet flat on the floor, and you should have an office chair that provides good lumbar support (either adjustable or with extra padding in the lumbar region). Armrests should be included with the office chair, and they should be adjustable to eliminate shoulder strain.
- Arm and Hand Positioning – The position you’re forced to hold your arms and hands in when seated at your computer can put additional strain on your body. When seated and using the keyboard, your elbows should be at 100 to 110 degrees (open). The keyboard should have a negative tilt so you can keep a neutral position in your hands and wrists. Keyboard trays should be wide enough for both the keyboard and the mouse, so you can use them without raising your arm to another position.
Breaks, Stretching and Exercising
It might sound counterintuitive, but office workers should engage in regular stretching and exercising while on the job. This helps to eliminate stress and strain, and enhances blood flow, which can increase comfort as well as productivity. Regular breaks are also important to help prevent workplace injuries.
- For every 20 minutes of typing, you should take a 20-second break
- For every 20 minutes of typing, you should look away and focus on the middle distance for 20 seconds
- Every hour, you should get up and walk around the office or take a stroll to the break room
- Every hour, stretch your legs, arms, shoulders and wrists to enhance blood flow
These tips and key concepts will help enhance workplace productivity, but also reduce the chance of injury for office workers
