This has been a sometimes fun, but most often infuriating discussion between my wife and I, as well as other family members and friends whenever we bring it up: which side of the bed is the front? Is it the foot end? The side where the heads are? Or are you a rebel and is it the side you get out of bed at?
I had a setup like this a while back. I’m going with the foot of the bed is the side that most easily lets you jump up and land on your back.
