Couples sleeping together sometime have disagreements over how warm or cool the room should be, and the top sheet in the bed can be a source of contention. Cotton or flannel? Now a company called OppoSheets thinks it’s hit upon a solution. Their product, the, uhhh “OppoSheet,” has two sides: One half is cotton, the other is flannel. So now folks who share a bed can have their favorite type of cloth covering them at night. Only drawback we see? A 600-thread count queen-sized sheet set goes for $289.95. Yowza! Folks who are as cheap as us could do what we and the missus do: We each have separate twin-sized top sheets. End of problem, especially if one of the sleepers (Visual: Throwing a sidelong glance at the wife) is a “sheet-cocooner.” See them for yourself at OppoSheets.com.
