I think the concept of a safe place or position is important. When I'm sick I always want to lie on the floor, and both times I have birthed kneeling on the floor, leaning over a couch/bed. With dd I also wrapped myself in a sheet, because it made me feel safe (I was nude underneath)

There is no right way to birth...the important thing is that it's your choice.

This was much my experience too. When in pain, upset or scared, I've always felt safer on the floor. Giving birth, and in fact 99% of my labour, I was on my hands and knees on the floor, in the bathroom There were times when my doula got me up to sit on the toilet or a birth stool to help DD around the bend, and moving from my 'safe' position was excruciating. I assume it would be the same for anyone and their 'safe' position, regardless of where that is.
