My favorite pillow! This one pillow solved all of my problems and it can last a long time thanks to coming with fill.

they are amazing super soft great for my neck perfect high
At first it seemed a little hard to get used to had to take quite a bit of stuffing out of the pillow, but when I had it adjusted to my desired firm it’s absolutely wonderful to sleep on. I’m now only using one pillow instead of two for the first time ever.
Love the pillow the softness, the comfy is really good and thank you for the relaxing sleep on the neck part it helps a lot!!!
Nice pillows 😎

Insanely comfortable and adjustable. Best pillow!!
These pillows are way too big. They have way too much foam inside of them and cause severe neck problems when sleeping with them.
OK, I think it’s ridiculous to include that little bag of extra fluff because it’s very hard to add to the pillow. You just have blue fluff falling all over the place and I don’t think it made it any bigger. It was an OK sleep
