ALIZA™ Sigma Medium Back Ergonomic Revolving Office Computer Study Mesh Chair Adjustable Height Push Back Medium Back (Black & Grey, Medium)

As the average length of the workday increased, and more and more people began spending more time sitting, the realization dawned that chairs with additional support were needed. Ultimately, this is what spawned the ergonomic movement, which saw the creation of office chairs with much better lumbar supports, fostering better overall posture. If you spend several hours a day sitting in front of your computer, then you need a chair with ergonomic supports. You'll pay more for it, but the extra money will save you doctor and chiropractor bills.
