An average office worker spends about six hours a day sitting at work.
Keep in mind you also sit in your car on the way to work and probably sit some more on the way back home only to sit through TV and finally lie in bed all night.
You don’t need to be a doctor to realize that all this sitting will take a toll on your health.
The least you can do is to get an ergonomic chair for your office and adjust it accordingly to fit your needs. But here’s the problem; most people don't have a clue how to adjust their office chairs.
No worries, we will show you how to how to adjust office chair seat angle in a bit. First, what is the correct sitting posture and what's the big fuss about it?
Everyone seems to be under the impression that good posture involves seating with your back upright, feet firmly on the ground and knees bent at 90 degrees. Well, this is correct to an extent but not completely accurate. You cannot align your body in a fixed position all day long and expect to stay healthy.
Ergonomic seating involves changing your posture throughout the course of the day depending on your body and the task you are doing. All the while, remember to keep your body straight and your chair well adjusted. Incorporate short walks in between hours of seating to avoid staying in a fixed position for long.
This simply adjusts the height of your seat by lowering or lifting it up. It helps in providing an ergonomic seating position by adjusting the height to a comfortable height depending on how tall you are. A pneumatic cylinder attached to the seat controls the lift and drop action which is triggered by a lever often located on either side of the seat.
Proper seating posture requires your legs to be firmly grounded. If the seat cushion is too large, your feet will be hanging from the chair and not touching the ground. Small seat cushions leave you sitting at the edge of the seat which is bad for your back.
Seat depth adjustment helps in moving the seat cushion back or forward to fit your height accordingly.
When typing, your wrists should be at the same level or slightly below your elbows. The placement of your arms should be wide enough to match the size of your shoulders. For this reason, you should get a seat that has an adjustable armrest.
Adjusting the height of the armrests helps with aligning your wrists with your elbows, hence sparing your shoulders a lot of straining. Side armrest adjustments either widen or expand the distance between the armrests accommodating your shoulder span.
Tilt enables you to rock your chair back and forth to a certain specified degree. This is great for initiating motion hence preventing back injuries as a result of being seated in one position for long.
Tilt tension controls the degree at which your chair rocks when tilted. It often determines how much force you will need to tilt the seat back. Using a knob located underneath the seat near the front, you can set the tilt tension to your desired degree.
Manufacturers often consider tilt and tilt tension as different settings but since they control the same feature we consider them to be the same thing.
Many chairs come with the ability to adjust the backrest height. This is quite different from adjusting the chair’s height as it involves changing the backrest as opposed to the whole seat height.
A backrest that adjusts helps to position it in the right angle which assists in suitable lumbar support depending on your height.
Look for one with an adjustable headrest to give your head, neck and shoulders the support they need when working.
Modern office chairs are starting to include this feature alongside the tilt function. Synchro-tilt helps tilt the chair while keeping the seat cushion at level with the ground. This works by making the backrest tilt twice as fast as that of the seat cushion, hence preventing the entire chair from completely rocking when tilted.
