I wanted the flexibility of a down pillow with the support of a fiberfill pillow, and the standard fits the bill. The best sleep investment I have made in a long time, and absolutely worth it!
I previously had one of those contour pillows to better support my neck. This pillow is almost a good, but not quite. Still, it is much better than some of the others we have tried because it much more easily adjusts its shape. I'm still adjusting to it.
