Duvet and Pillow, warm/cold technology

I need a team which can make me a prototype for a Duvet and Pillow which can be turned up like a volume bar in warm and cold.

I don't know which technology there is needed, but i need a prototype for this product.

DUVET:

When it's cold outside, you can turn up the warm in the duvet.

When it's warm, you can turn down the warm (turn up the cold) in the duvet.

Same as pillow.

Please bid if you can DO this
