Ours is against three walls - you can only access the bed from the foot. It’s also four feet up in the air as we put a closet under the bed. Turns out you can put on a fitted sheet while you’re on the bed really easily - just lift the head, bending the mattress and the corners in slightly, get the corners on, then off you hop and pull the corners onto the foot - takes 30 seconds at most, and there’s no walking around or lifting the entire mattress.
