Hi Pearl,

Many thanks for your enquiry.

As we do not manufacture products for Tempur, it would be inappropriate for us to provide an opinion as to whether it would be safe to use an electric blanket with your current mattress. Having said that, Tempur products are primarily constructed using memory foam as the main constituent and this uses body heat to function and the application of an electric blanket may make it soften too much.

It may be prudent to seek assurance either directly from Tempur or a recommended retailer to be absolutely sure.

We trust that this helps,

Kind Regards Gary
