In the description of this pillow, it states it contains slow release noodles. I have not heard of them and I have tried probably all major latex retailers in my quest for the perfect pillow. Upon sleeping on this pillow, I noticed it has a very firm feel, but it also conforms to you. It feels more like memory foam to me than a bouyant bouncy latex pillow. It was a good hugging pillow , but I did not like that I felt my head sinking in and waking up feeling like my pillow shifted. I would use this as a body pillow for myself. But my son took the pillow from me, and he loves it. If you like the firm memory foam pillows and don’t want the smell and chemicals then this is a good substitute. The shipping was fast and materials were quality.
