If you're a restless sleeper – or simply prefer to keep bedding off your feet – you'll appreciate this sheet and blanket support. Our blanket support lift is vinyl-coated and won't snag or rust; slips under mattress, holds bedding up, away from feet. This blanket lifter has 20" arms to accommodate many deeper mattresses. Blanket raiser assembles easily without tools, and folds flat during the day. Instructions included. This blanket support is safe for electric blankets, too.
