I had a friend who had her last child at home in bed, no drugs. She seemed to find it far preferable to the hospital setup - you can move around and find the position best for you.
I’ve never had a child, but putting a woman on her back in stirrups - largely to accommodate the doctors - always seemed very unnatural to me.

I think other cultures use gravity to help with birthing - as opposed to trying to work against gravity
