I'm bad at this *sheet

I'm bad at dealing with sheets, bed sheets, bed cover sheets. 

So, wouldn't it be better if the bed had holes at each corner and the bed sheets has rubber screws to be attached in the bed? Then make the bed sheet in the form of an opened up dice, so at the sides of the bed, the wings could be tucked in. (ok that would leave the corners opened, maybe put a zipper at each corners?). Then when it was time to wash the sheet, the rubber screws could be unattached from it, because it is mushroom shaped. 

For bed cover sheet, the zipper should be all the way from the top side to the bottom side, opened it up like a book, put the bed cover in, tie it up to the sheets, and then zip it. (Ok, on the top side the zip would cause discomfort, so maybe a wing to cover it that could be buttoned? At the end of the wing you fold it inward and then button it).
