Query: dissapointed

I have used the neckbone pillows for years. Every so often when they are not as firm as I would like, I buy a new one to replace it. That is why I purchased this one. Well, apparently they changed the inside filling since I last purchased this product. A fresh marshmellow is more firm than this pillow was. I went back to using my old one because it still offered more support than this new one did.
