Can you fold a fitted sheet?

I reckon the sheets are all the same. But the point of sewing two together is that there's no other way to tuck in the topsheet. The mattress is just ttooooo heavy. Water weighs a lot.

Plus, there are other things on the mattress, like mattress covers. Those aren't strictly "fitted" as much as they're flats with straps that pass under the corners of the mattress.
