I bought the small neck pillow 2 months ago to replace a lost tempur pedic pillow. My neck isn't sore anymore and I'm quite happy with it. Upon reflection I would have bought the medium pillow as a standard pillow case tends to fall off easily.
The Queen Large (24" x 13" x 5"): is the perfect pillow for me. i can finally sleep at night without pain. I must sleep on my back and this pillow works for me. $159.00 is money well spent!
I think this is my 3rd pillow I've bought over the years. I travel with them everywhere! I did notice a slight difference in the feel from those I had for many years. It is all good though because I immediately felt relief in my neck and upper back when I put my head on it. I'm 5'6" and have always used the small size. If you are new to these it does take a few weeks to get used to the feel especially if your neck is not 100%. Like many others that ordered these I have cervical disc issues and don't know what I would have done without this pillow. I'm hoping I can order/find the replacement for the satin cover I have but not sure it's available anymore.
I have one old "neck support" pillow that is perfect...I ordered another one and it's so hard, I hurts my neck and the bones beneath my ears and is unusable.
My husband bought me this pillow several years ago and other than my engagement ring, it's the best present he's ever given me! I carry it with me when I travel.
