Blanket or Comforter on Top of Electric Blanket
Despite many newspaper and internet articles to the contrary, most electric blankets or electric mattress pads designed for use in the United States allow for the use of any other bedding you wish -- except another heated product (overheating could occur with two products operating simultaneously).
For example, a common question we get is whether one can use a comforter on top of an electric blanket. Most models of warming blankets allow for this – read your particular User Manual first. If you no longer have your User Manual, check out the web site, email or phone your blanket’s manufacturer. Contact information for the major manufacturers can be found on our Manufacturers Contact Information page.
We do usually advise though that if someone is cold enough that they need a comforter on top of their electric blanket, they should consider a heated mattress pad, rather than a heated blanket. Heated Mattress Pads are ALWAYS warmer than Heated Blankets. See out article comparing the two products.
