If you are reading this you are likely sitting in a chair. The time spent sitting at a desk has greatly increased with use of the desktop computer. The workforce has moved from industrial labor to the cubicle and we now sit for longer periods of time then we ever did. The only thing the average office worker does more than sit is possibly sleep. Given that a person may sit for as much as eight hours a day it is no surprise that there has been an increase in back pain. We only spend a small amount of thought on the design of office chairs used in everyday life.
Very few bodies are exactly the same so some amount of customizing is needed on office chairs . The most important aspect is lumbar support. While higher end executive chairs tend to have lumbar support included, you can find support cushions at most office furniture stores should your chair lack the option. Other adjustments include setting the seat height until your knees are bent at a 90 degree angle. Backrest support is more a personal preference but a good rule of thumb is to have it reach the shoulder blades.
The correct chair will make a large difference in your day. However, despite even the best seating arrangement be sure to get out of the chair every hour or so to help blood flow and to stretch any stressed muscles.
