Thank you for this invention, it is exactly what I’ve been hoping to find for my husbands sensitive neck. He almost broke his neck 20 years ago and hasn’t been able to find a pillow… I really thought this would be the one, but even with zero filling in the middle of the pillow… his neck can’t tolerate even just fabric. But I love mine so much I just couldn’t get myself to return his (and I would normally consider myself a bit frugal!) so I have two all all for myself! I love that they fold in half so easily and store away compactly. Overall it is great to be able to sleep on my back with only the neck support I need; and then roll on my side and simply have the full support that I need right there easy without all the shifting and fluffing - that was never enough - but now it is!
