depends on what side the missus sleeps, the last one slept on the right, the one before on the left so in the end it doesn't matter cos i like to
on top ... (no i dont)
all over the place i have the bed to my own and its a one-person matrass but these days with the house to me i usually sleep on the couch half the time ...
maybe you're familiar with it ... adapt to survive :p
