Lovingly called the ' Chair that you wear', the Nada chair consists of a 'slouch-busting sling' that aims to support your back however you're positioned. It does this by the fact that you essentially WEAR the hair, and that means your back is always supported by a bit of elastic and wire. It does mean you'll have amazing posture and should help to prevent back pain, but could you imagine getting away with this in the office? You're a braver soul than I am! $70 from Nada Chair
