Wait you don't understand why someone would push their bed in the corner? Or you don't understand why it's a problem for two people sleeping in the same bed if the bed is pushed in the corner?
Washing my blankets as frequently as they would need it would wear them down much faster and for that matter, sheets are just easier and more efficient to wash. That's why I use a top sheet at least. It's not a comfort thing for me.
They're not too bad, just start with them inside out, grab the corners, and pull through. And it makes it easier to make the bed later because you don't have to deal with the top sheet.
Perhaps too afraid to ask for styling advice for himself and "asking for a friend" would invite too many follow up questions so he has to make up a girlfriend to impress.
