Chairs such as these are not the most comfortable for sitting in for long periods of time. It is better if you can purchase an ergonomic chair, or a kneeling task chair to give your body proper support when sitting for extended periods. anonymous@oola.com

Mesh back chairs have become extremely popular in recent years. The mesh back is available on all types of chairs – visitor, meeting, task, executive, and drafting chairs. Not only do they look good, but modern technology has made them reliably constructed, and these are also very supportive for the chair user. The mesh material allows air to flow through the back of the chair often keeping the chair and user cooler throughout the day, particularly when the chair is being used for long periods of time. It helps maintain the natural spine posture while giving adequate support to lower and upper back muscles. Their ergonomic design and light-weight structure keep you comfortable all day long. With an upholstered seat, mesh chairs offer contoured support for excellent back support.
Task chairs are usually found on specialty chair websites. You could also try office supply stores online such as Office Depot and Staples, as they sometimes sell them as well.
I think that places such as Walmart, Staples, Office Depot, etc would carry them. Any store that sells office decor, should have office chairs readily available.
