IDK about chairs, but this is why it's important to try and stand for at least a minute or two once every hour (or at least every couple of hours). Sitting in a chair is not a natural position and it inherently messes with our spinal alignment and tightens the joints around our hips.
Also, exercise and lots of stretching. We're gonna be spending most of our lives in windowless rooms producing beats - We need to take care of our bodies whenever possible.
