generally not recommended to use a weighted blanket on top of an electric blanket. Weighted blankets work best when they have direct contact with your body to provide even pressure. Placing a heavy weighted blanket on top of an electric blanket could potentially damage the electric blanket and may not allow the weighted blanket to provide its intended benefits. If you want warmth and the comfort of a weighted blanket, you can use them separately by turning off the electric blanket while using the weighted one. Always follow the safety guidelines provided for your electric blanket to prevent any issues.
