The picture clearly shows two controls, but please be aware that it only comes with one. Both sides of the bed heat equally, so both partners have to have the heat. I was disappointed in this, hence the three stars. However, the mattress pad heats beautifully and makes for a comforting winter's sleep. When you touch the heated pad, it feels cool; you only feel the heat when your body weight is fully on the bed. It goes off automatically after so many hours, which is a nice safety feature. I just wish the two sides heated separately.
