Place the Bedge on top of and near the head of your regular mattress (it will also work on water beds). You may cover the Bedge with a regular sheet to match your bedding (folding the sheet around it like wrapping a package) or use a fitted crib sheet which will cover the Bedge snuggly. When ready for sleep, position your head a few inches from the top of the wedge. You will be most comfortable sleeping on your back or side. Your own pillow can be placed under your head for added elevation and comfort.
