How to Adjust the Height of an Office Chair
There are different styles and designs of computer or office chairs. Most new models are adjusted pneumatically. Pneumatic office chairs have a lever or a button below the seat that you can push or pull to adjust the height. Older computer chair models can be adjusted by turning a thick bolt (these bolts usually have a thick plastic molded cover with finger grips). Adjusting the height of your office chair to fit your body type is very important. Back ache and pinched nerves can occur otherwise -- especially after long periods of sitting.
