• Fetus (41%) – curling up in a fetal position. This was the most common position, and is especially popular with women.
• Log (15%) – lying on one's side with the arms down the side.
• Yearner (13%) – sleeping on one's side with the arms in front.
• Soldier (8%) – on one's back with the arms pinned to the sides.
• Freefall (7%) – on one's front with the arms around the pillow and the head tilted to one side.
• Starfish (5%) – on one's back with the arms around the pillow
• Rest of them did not know how they slept
