not convinced by the comments! I'm going to see real pro to a pillow for cervical !! the shape memory disturbs me, and then we do not sleep in the same way toujour! sorry
Small price, small results. Square molded regular foam. A little too firm for my taste. Argument "memory" lie. Possibly to put his feet. A little pricey for what it is. In a market it costs 2 or 3 euros.
