Which office chairs provide the back support you need during long workdays at your desk? Here are some must-have features that are recommended by Chiropractor Dr. Rodney K. Lefler on Spine-Health.com:

• The seat height should adjust easily, allowing you to sit with your feet flat on the floor and your arms even with the desk surface.

• The seat should tilt, and should be deep enough to let you sit with your back against the backrest.

• There should be a lumbar support that adjusts for both height and depth, so you can find a setting that supports the inward curve of your lower back.

• The backrest should be adjustable for both angle and height.

• The fabric should be breathable, and padding should be thick enough to provide comfort during long periods of use.

• Armrests should be adjustable up and down, so your arms can rest comfortably on them while your shoulders are relaxed.

• Swiveling should be easy, so you can turn easily to reach different articles in your work area.

Buying a good chair for a great price . . .

Consider buying a used desk chair. Due to the current wave of company downsizings, lots of used office furniture is currently available – some at liquidation prices. To find a company that sells used office equipment in your area, visit the Yellow Pages online or search online for “used office equipment.”
