How comfy is your chair at work? Sixty percent of workers report being planted in their chairs for more than six hours a day, says a recent study performed by WorkRite Ergonomics. The study also stated that nine out of ten workers report end-of-workday aches, pains and fatigue.

Sitting for long periods of time puts pressure on the disks in your lower back and can disrupt circulation in your muscles. Also, holding the same position for long periods of time can cause repetitive strain injury.

It is a good idea to stand up and stretch every 20 minutes for at least 20 seconds, according to Circadian Technologies. Using an ergonomically sound chair can also help.
