I have one of these as well - I have RSI, which is caused by and means lots of back pain. It is a useful thing - I use it to make normal chairs "safe" so they don't hurt my back, and also to allow me to sit on grass etc. without hurting my back or hands. There is no substitute for a decent chair though - but given that's about $1,000 and a Nada chair is a small fraction of that..... :-) >A coupla months ago someone (ooops! Sorry... I forgot who ya are) posted on >the List about a device called a "Nada Chair," which had brought them >back-comfort when sitting at the keyboard. > >This is an endorsement for this reasonably priced, terrific "thingee," <smile> >and please note that I'm not employed by or otherwise connected to Nada Chair. --------- My opinions are my own, NIP's opinions are theirs ---------- Simon J.
