Chair with back support
Can anybody recommend a reasonably-priced--i.e., not Aeron--chair with decent back support that I could buy at, say, Staples, or Sears, or some other store I'm likely to find in "the mall?"
(By chair, I mean "chair," not some sort of New Age contraption where I don't sit but kneel, or a Roman-style couch where I recline while dictating to a scribe.)
I'm starting to feel some stress on my lower back, probably because I'm typing too much and exercising too little, but still, I feel that a chair would help.
Unfortunately, the last chair I got from Staples had these arm rests on it, and for whatever reason, I ended up twisting my body to sit in it, with results even more painful than before. But they can't all be like that.
Actually, the best chair I ever had was an old wooden folding chair from an Episcopal church. Flat seat, flat back, skeletal appearance, it gave total support and was very comfortable.
Readers, do any of you have recommendations?
UPDATE On rereading, I see that I didn't say "chair for sitting down in front of the computer and working at." The fact that this seems to be the only reason I sit down... I don't know what to make of that.
