Steelcase have 30% off selected models. Some appear to be cheapest ever. Free pick up from Mel or Syd, otherwise coming up as $105 delivery for me but presume it's variable depending on location.
Be careful when choosing as some chairs do not have lumbar support.
Chairs with arms and lumbar support:
Series 1 $759 -> $531.30 (+ $42.00 headrest option)
Series 2 Mesh back $989.00 -> $692.30 (+ $94.50 headrest option)
Series 2 Solid back $1,059 -> $741.30 (+$91.00 headrest option)
Gesture Cloth $1,814.00 -> $1,269.80 (+ $261.80 headrest option)
Gesture Leather $2,683.00 -> $1,878.20 (+$261.80 headrest option)
Some desks are included but I haven't looked into them. Ended up choosing the Series 2 Meshback with headrest (rather than Series 1) as it feels more premium (firmer netting), its armrests don't move when reclining and it has higher back for taller people. Gesture seat is very thin (intentionally) at the back and reviews suggest it can lead to tailbone pain over an extended period of time. Obviously do your own research, visit their showroom in Melbourne or Sydney or Arki Environments in Brisbane.
Damn, no gesture with 4d arms and headrest:(
