It will do, I brought mine second hand a while back now and still as good as the day I brought it into my home office.I've just ordered a refurbished Aeron from simplyaeron.co.uk.
Mk2 Black Size B Fully Loaded Aeron Chair - Lumbar Support, Levered Arms, Tilt Limiter, Front Tilt, Vinyl Arm Pads - Just over £400 + £12 delivery, hope my back thanks me for it.
I just got fed up with buying cheap £150 to £200 chairs that promised loads and just fell apart within 18 months.
