Modified twin xl - with a further 5" added on. My wife sleeps in the queen with our daughter in the same room because she still gets up a few times a night to feed. That way I can sleep the whole night through and be well rested in the morning.
I did sort of miss my weird bed, as it's the only one I can fit on without my feet poking off the edge. I'm only 6'5", but this allows me to put the pillow up top, not have to force my head up against the wall, and still have my feet on the bed. Everything else has them dangling.
Only downside is that fitted sheets are not made for that mattress size so I have to splice in fabric and extra elastic onto a premade twin xl set.
