I used to have a mattress pad from Sunbeam. The improvement I see in Rest Secure are: 1) the power cord connector is on the side, instead of on top of the mattress like Sunbeam, which is annoying when you sleep on it. 2) warmer heat zone for the feet, it does get colder that side. 3) the setting control has 2 buttons, 5 levels, Sunbeam has a rotational knob for 10 levels. I have to say buttons looked less sophisticated, but it is easier to manipulate, especially when you are half awake at night.
