A Battle Creek® BedWarmer™ is the perfect solution for poor circulation or cold feet. People with Arthritis, PAD, Chronic Fatigue, Fibromyalgia, Reynaud's, MS, RLS and many other problems can benefit from the soothing warmth. The 18" X 36" size can warm just one side or all across the bottom of the bed. The standard, single temperature model warms with a low, consistent heat to surround feet and legs without heating the whole bed or raising the thermostat and features a lighted on/off switch. The deluxe, dual-temperature model allows the user to heat the unit quickly to warm cold feet, and then switch to low heat, to maintain warmth through the night. This model features a luxurious fleece cover that adds an extra layer of comfort - especially if you prefer the BedWarmer™ on top of the sheet.
