No, no size queen at all. I find the load fit in my 1515 to be tight after washing in the 1918. But then, I tend to wash "full" loads which some would say they were "Bob" loads. If you did that with the 1926, the 1515 would definitely be "over-Bobbed".
No, KA here (yet). I'd love one, but am not rushing for one (yet).
