Why it is important
Namely, technological advancements contributed to an increased number of sedentary jobs. In fact, there are more than 83% more occupations that require employees to spend 8 hours of sitting then there were in the 50s. Unfortunately, this resulted in an increased number of people who suffer from cardiovascular diseases, obesity, elevated heart pressure, and cholesterol levels. All due to an extended amount of time we spend sitting.
Lower back support
When inappropriately seated, your lower back is the first to suffer more serious consequences. The issue here is the lumbar spine that has an inward curve. So the longer you sit the more you are likely to slouch. To prevent your body from sliding into an inappropriate sitting position, pick an ergonomic chair that is designed to support the natural curve of the spine. Chairs which come with the merged seat and backrest should at least allow you to adjust them forward or backward.
Armrests
Many choose office chairs which allow you to easily remove and install armrests, especially people who spend most of their time working on a computer. If that is the case, be sure to adjust your chair height so that you can sit upright, with your elbows and lower arms on the table and your hands above the mouse and the keyboard. At no point should you feel the strain in your arms while working.
Wheel and swivel base
Almost all modern chairs are designed with a wheelbase, but be sure to check how easy it moves on a carpet. It should also swivel freely so that you can reach different parts of the desk and office quickly and almost effortlessly.
Bottom line
The level of comfort largely depends on the body build of a person sitting on a chair and their specific needs.
