Steelcase do make some very good ergonomic office chairs, i sat in one at a show recently and yep there very good. It's always nice when you get something a little better than what you expected, especially when it has the benefits of a good ergonomic office chair. Raghu, kick up a fuss, most bosses now realise the money lost through bad back's from sitting all day in a rubbish office chair, complain about your back, even through a couple of sick days, your new ergonomic office chair should soon follow.
There are many Ergonomic Office Chairs out there for below $500, the best advice i can do to anyone is to shop around. But the most important thing is to look after you back.
This Chair looks as mad as they come, but if it has all the benefits of a good Ergonomic Office Chair and gives the end user relief from the torment of back pain it's all good. I want to have a go on one!
