Ergonomic ball chairs

[DrTre]

Any good? (at relieving lower back pain and improving posture etc)

Like this:

Or better off just using a ball?

I've just a kneeler chair before to good effect, but they don't half hurt your knees, though I'll likely go back to one if no one says these are outstanding.

Cheers


ETA. Actually I'll just use a ball, sod it, it can't make my back any worse. Rowing helps but not enough
