I'm always on the right...not sure why, but I think it's because the left has always been closer to the ensuite and DH gets up for work at 4:30am and I don't want to be woken by the shower. Because the additional 1/2m makes All the difference to the noise level!

We don't have a zombie/intruder proof side because it's the quilt/sheet that protects you from bullets and knives, not what side of the bed you have (and why I MUST always sleep with something pulled right up over me)...Derrr, doesn't everyone know that?!
