Now the modern market offers a lot of pillows, which call as "orthopedic". But on closer inspection, they are not at all like that.
Why are they so called?
It's just to better sell them. Since the people in recent years are not interested in pillows in general, namely tempurpedic neck pillow.

And they can add a mysterious "memory effect" to the name.
