Super King Size electric blankets come in two main types, fitted under blankets and over blankets. A 6' fitted under electric blanket will heat the body from underneath and add extra warmth to your bedding and bed.
A 6' over blanket will warm you and your bed from the top with many designs available with heat sensitive technology that adjust to the temperature of the body and room while you sleep. The super king size over blanket can either be placed on top of the bed, or inserted into a duvet cover.
With the added convenience of being machine washable and tumble dry safe, a good quality 6' electric heated blanket will also help keep your bed fresh and clean.
