I would suggest you go to an Office Max or Depot and try all their chairs, even if you have to take a book and sit in them for 20-30 minutes. They have different sizes and lumbar support and for under $200 or way less you could get a good chair. These people make me think of the the organization 10-15 years ago that sold light bulbs that were supposed to last 10 years for $15.00 each when reg. one was .25- .50 cents. I find chairs with arms are easier on my back as I can rest my arms when doing some things and that takes strain off my back and neck.
