Do you put an electric blanket over or under a foam topper pad?

An electric blanket should be placed under a foam topper pad for the best results. This is because an electric blanket generates heat, and placing it under the foam topper pad will help to distribute the heat evenly. This will ensure that the sleeper is evenly warmed, and it will also help to prevent the foam topper pad from overheating. Additionally, placing the electric blanket under the foam topper pad will help to prevent it from shifting or bunching up, which could cause discomfort.
