Stretching exercises help a lot. I prefer classical dance warmups, some people like yoga. When you sit pull your chin down. Lots of people stick out their backs and reach forward with their chins and this practices slouching and bad posture.
I guess my history as a pianist helps ME bc pianists do not sit all the way back on the piano stool. We sit forward, left leg bent so that the left foot is tucked under the stool to help balance the right foot, at the ready to use a pedal.
Try sitting forward on your computer chaire, and try tucking your feet under your computer chair and cross them. This will help, too.
It's probably a matter of bad habits. Most people have an uneven spine, but you can correct this with stretching and muscle workouts.
