How does the bedwarmer stay in place under the covers?
The 115 volt fitted bedwarmer is very similar to a fitted sheet in that it covers the entire mattress and is held in place using elastic all around the skirt of the bedwarmer. The 12 volt bunk warmers are held in place by pinning the warmer, stretched out on the mattress, through tabs that are located along the ends and sides of the pad. Pins are provided.
