Where in your bed do you usually sleep?

King size mattress.
On my back: left.
On my stomach: right.

I sleep on the left, cats on the right.

I have a double bed. I chose 'sleep on the right' because that's where I start each night. I move around a ton when I'm sleeping though. I might wake up on the right (though it's doubtful I stayed there all night), or I may wake up on the left, in the middle, sprawled out over the whole bed, or hanging half off the bed!

Other: I don't have a "left" or "right" as I sleep on a very narrow futon on the floor. It is not as wide as a twin bed. But I can still turn to either side or on my back okay.

I sleep on a queen sized waterbed and I usually sleep in the middle.

I sleep in a single bed. I turn from side to side, plus on my back.

Well let's see, if I were sleeping on my right side, left of me would be the ceiling. If I were sleeping face down, that would be to my right.

Generally I do at least begin sleeping on my back though, so I'll say the left.
At my last home I slept on the right; It depends on the location of the bed.

I always sleep on the left, but just because of the configuration of the bedroom.

I always sleep on the right side, my SO has the left side.

I sleep alone in a double bed and sleep on the right hand side. Only because this is the side furthest from the window, which I think is my deciding factor.

I have a king-size bed and sleep on the right, since the left side is covered with books, DVDs, my CPAP machine, etc.

Queen, left.

My position varies it is left and right then middle then across the bed and hanging off the bed and I have a double bed

Single beds they are so tiny I do not know how you do it without falling on the floor?

I have a kingsize bed, but I sleep at the far right edge. I've always been an edge sleeper - I like to have my face as close to the edge as possible, if not overhanging it. I usually have my knees and arms right at the edge as well. Somehow, I feel more comfortable like that. In the seven months I've been here, I've never laid on the left side of the bed at all, and I've barely encroached on the middle.

LOL. It's a day bed up against the wall, with white/brass rod iron side, and ends. It's a twin bed mattress. I really like it I've never fallen from it yet. I'd much rather have a nice full sized bed, but I have my computer set up on an "L" shape desk in my room... It takes up a lot of room.

This whole survey has had me wondering what you are getting at, as to what underlying presumptions it was making.

Factors involved may include:
Where a body prefers to lie, relative only to a bed itself.
Location of mate or pets sharing a bed.
Proximity to door, closet, dresser, or computer desk.
Orientation in respect to a wall or sunlight.
View of a television.
Bed used concurrently as laundry, book, or project storage.

I'm guessing in your case that neither side is against a wall, and that the side you chose is most convenient relative to getting dressed. For many people several other factors are involved as well, and thus little is to be gleaned from survey results without accounting for these factors (which is ok).

In my case, I'd sleep in the middle, except that one side is storage for excess pillows, and so I choose the convenient access side which also has the best TV view.
At my last home the opposite side was chosen for the window view which also had the safety of being a wall, even though I had to climb over my active-project and pillow storage to get there.

I'm an edge sleeper too.

Another weird sleeping habit of mine: I'm far more comfortable fully making the bed up with a fitted and flat sheet and a comforter or quilt and then just sleeping on top of it with a throw blanket instead of getting under the blankets and sheets.

Well, I sleep on a queen bed on the left side, close to the edge. Two weeks ago, I slept on the right side. The reason is I moved the bed to the other side of the room. I sleep on the edge because there is less chance of getting tangled up in blankets, or trapped. Once I was trapped under blankets sharing a large bed with two other people and I thought I was going to die I couldn't get out. When I slpet in the same bed with my SO, I took the spot she didn't want, so it looks like I prefer the side nearest the door.

Me too! Although I do get under the blankets and sheet, I'd much prefer a sleeping bag on top of the bed. And the edge as close without hanging over.

We even sleep the same way!!

Double bed, left side when I am single occupant. I am a restless sleeper, changing position a lot; but somehow I manage to stay on the left side.
