Reduce Work-Related Musculoskeletal Disorders
How many injuries due to work-related musculoskeletal disorders did your company have in the last year? The last 3 years? What did they cost your organization? Have you ever tried quantifying the value of lost time due to sick days?
Sitting in the wrong chair in your workplace, day in and day out can be uncomfortable. But it doesn’t stop there. Awkward or static postures, excessive force, highly repetitive work, contact stress or static exertions are all contributing factors to work-related musculoskeletal disorders (MSD). MSDs account for 33% of all workplace injuries reported in the U.S., with an estimated economic burden between $45 and $54 billion annually in workers’ compensation costs, lost wages and lost productivity.
The fact is: workplace injury can be prevented. Providing office workers with a fully ergonomic seating solution and ergonomic training can decrease soft-tissue injury and have a significant impact on productivity. In addition to taking regular breaks from sitting, an adjustable chair that allows the user to have movement throughout the day – even in the seated position – which helps increase blood flow to the brain and to the body, keeping employees feeling refreshed and energized.
We Understand Adjustability
Our seating systems are modular and highly adjustable, designed to reduce seated posture stress and risk factors that could lead to work-related musculoskeletal disorders. Recommended by ergonomists and health care practitioners, ergoCentric enables employees to easily change their posture throughout the workday.In short, we understand adjustability.
10 Essential Adjustment Features to Look For
Task chairs must be safe, well-built and provide support for the required working postures for the intended user to maximize long term comfort, productivity and to avoid injury.
Insufficient or lumbar support that is too high or low can lead to lower back pain. Look for a lumbar support that adjusts up and down, as well as in and out, to fit people of different body types. A large range of height adjustment is especially useful for those who carry additional weight in the buttock.
Seat that is too deep or shallow can cause lower back and leg discomfort. The seat depth must allow the user to sit back against the backrest, allowing the backrest to support the back properly. There should be approximately a three- finger width of clearance between the back of the knees and the font of the seat so the legs can be positioned without compression at the back of the knee
The seat should be wide enough to support the full width of the buttocks but not so wide as to put the armrests out of reach. This allows users to maintain comfortable pressure distribution across the seat and to adjust their posture.
The angle between the seat pan and back support should be greater than 90 degrees to help reduce stress on the structure of the spine. The angle between the backrest and the seat should be adjustable.
The seat pan should tilt forward and backward, should lock into any position to provide the variation in postures required by the human body, and have tilt tension control if the seat has a free float mode. This enables the user to easily recline reducing stress on the low back.
In general, the base of the chair should be the correct size and type for the size and type of chair as they provide the chair’s stability. If the base is too small there is the hazard of tipping and if the base is too big relative to the seat size, it becomes a tripping hazard. If bases are plastic, they should be made of 30% glass-reinforced nylon with a metal hub insert as it provides increased durability and strength.
For casters to work properly there needs to be a degree of friction between the wheel and the surface it’s being used on. Too much friction makes the chair difficult to move. Too little friction means the chair would move too easily. To avoid accidents make sure casters fit the intended use of the chair with nylon casters for carpet and urethane casters for hard floor surfaces.
Task chairs should have pneumatic seat height adjustment. This allows the seat height to be easily adjusted, act as a shock absorber when sitting down and allows the chair to swivel so you don’t have to twist your back when reaching for things.
- The backrest should be the correct size for the length of the person’s back.
- It must have a firm lumbar support built into its structure to provide the force necessary to reposition the lumbar spine back into its natural curvature.
- It must also have lateral curves to support the upper body, so as to reduce the amount of muscle activity required to keep it in the upright posture.
Adjustable arm allow the user to pull their chair close to their work surface and provide guidance and support when getting in and out of the chair. They also support the weight of the user’s arms reducing stress on the shoulders and neck.
