expired Herman Miller Aeron $990 at Living Edge until End Jan 2013
This was posted 4 months 24 days ago, and might be an out-dated deal
Similar to last year's offer: http://www.ozbargain.com.au/node/61634
I believe that the regular price is still around $1.4k, so while $990 may be a little expensive for a computer chair, it's a good discount. And it comes with 12 years warranty, that's a lot of comfortable OzBargain computer time :)
There are different specs and options for the Aeron, and tension on Whirlpool confirmed that this price was for full spec with standard base: http://whrl.pl/Rdqb1Y
Looking forward to go try it out!
