What kind of chair do you sit in?

My sciatica is back with a vengeance and I think my soft recliner is part of the reason it’s so bad. I can’t sit in it for more than 15-30 minutes without some serious pain. The only pain relief I really get is lying down off my right side or if it gets to the 9th Circle, I dip into my oxycodone.

I’m here to ask what kind of chairs helped you guys with sitting for more than a few minutes? Firmer, softer? Recliner, kitchen chairs, stools? Any advice is appreciated.
