I've had serious back injuries in the past and sitting at a desk would soon lead to poor posture and discomfort.

The three best things I found for my back are.

1. Be mindful of how you're sitting and keep that natural curve in your spine with your shoulders back and chest out. You don't have to be aware of it all the time just make a habit of checking in with your posture when you sit down or when you're changing tasks.

2. If you go to a gym then hit the rowing machine. Good technique requires good posture and its great for strengthing those muscles.

3. Get a ball like a tennis ball and put it between the back of the chair and around the base of your spine/hips. This gives you space to relax your shoulders back and maintain a natural curve in your back. Just as long as you feel comfortable.

I found that after a while maintaining a good posture gets easy and more comfortable than slouching.
