What is the purpose of fitted sheets and flat sheets on a bed?
I found these answers while Googling:
[li]Fitted sheet collects sweat and shedded skin, preventing it from getting into your mattress[/li][li]Flat sheet collects sweat and shedded skin, preventing it from getting into your comforter, which is harder to wash/replace[/li][/ul]
Are these the only reasons? They’re fine reasons, and I’m not going to start laying directly on the mattress like a filthy animal, I’m just curious. The SDMB is a good candidate place for somebody to know other more arcane or interesting explanations.
