Standing desks and ergonomic chairs may not be as beneficial for your posture as you think.

That's according to a new study from Sydney University, which has found that there is no scientific proof that these pricey interventions actually work.

Professor Chris Maher told Larry Williams that it is a very simplisitic view that a different desk or chair will fix people's posture problems. 

"My concern is that people are being sold and marketed these quite expensive devices but there's actually no good evidence that they are actually fit for purpose."

Maher says different forms of exercise will likely be better for people's back pain.

He says that the change in environment is likely convincing people that the new chair or desk is working, but that the furniture can do more harm than good for certain types of back pain.
