It's still a while before powered exoskeletons become common among factory workers (although closer than you think) but a new, simpler mechanical enhancement might make life that little bit easier for workers on their feet all day: a wearable chair.

Invented by Zurich-based start-up noonee, the Chairless Chair looks like a pair of prosthetic limbs strapped behind the wearer's own. It’s secured by belts around the hips and thighs and as soon as the wearer sits down it locks into place, providing relief for aching legs.

Nooone say that the device could be sold to average consumers one day (you’d never have to worry about finding a seat on the tube) but at the moment are targeting industrial workforces around the world.

The chair uses a 6V battery to keep it powered.

In Europe, musculoskeletal disorders (MSDs) caused by physical strain affect some 40 million workers, accounting for nearly half (49 per cent) of absences from work and 60 per cent of permanent work incapacity.

This is damaging to both employees and employer, with Fit for Work Europe estimating that “poor health due to muscle and joint pains represents an estimated cost to society in Europe of up to €240 billion” (£192bn).
