Can you use an electric blanket on gel foam mattress?

It is not advisable to use an electric blanket on a gel foam mattress. Gel foam mattresses are made of a temperature-sensitive material that can be damaged by heat. The heat from an electric blanket could cause the gel foam to melt or deform, which would void the warranty on the mattress. Additionally, electric blankets can be a fire hazard if they are not used properly. It is important to follow the manufacturer's instructions carefully when using an electric blanket, especially on a sensitive gel foam mattress.
