It is made of innovative fabrics that are very soft to the skin and are effective in preserving heat.
You do not need to add a top blanket for insulation as it comes designed with one already.
It is very comfortable to use since its wires are thin and very flexible eliminating any stiffness.
Heat is distributed evenly on the blanket due to the wires running zigzag reducing chances of potential cold spots.
It has wire sensors that adjust the settings on the temperatures on the blanket to automatically adjust it to perfect temperatures.
It comes with dual temperature controls.
The fabric is quite slippery and so can slip off easily when you toss and turn during sleep.
