Which chair would be better, CD or duo bag?

A. 1

If you're changing chairs because of a bad back, I recommend a disc chair.
It's also called a knilling chair.
There are several kinds, so try searching on the Internet.

If you're going to use it at home, it's better to buy a gym ball than a chair.
It's much cheaper than a chair, but it's also good for your waist disc.
