Took a while to get used to the noise, and some fine tuning on the amount of fill, but my Hullo pillow is now my guarantee of a good sleep with no stiff neck or shoulders in the morning. I’m a back sleeper and Hullo lets me have neck/cervical support while still letting my head rest just slightly to the side to prevent snoring.
I bought the small size which sideways in a standard pillow case that I then fold in half. To adjust the softness I took out enough hulls that I filled a little pillow that works great as a lap pillow to prop my Kindle or iPad on when I read.
