underblanket
Sheet goes above
An underblanket is a layer of padding or insulation placed beneath the bottom sheet on a bed, providing extra warmth or cushioning.
Electric underblankets heat the bed from below: I turn on the underblanket before getting in on cold nights.
Distinguished from a blanket, which goes on top.
