I had a Tempur-Neck Pillow for ten years. This is my second one. I won't sleep without it. It is the best pillow I have ever had. I have had cervical spine fusion and this pillow is the most comfortable for me.
Pillow is very small and the medium firmness is way too hard. Not really big enough to roll over and not fall off the pillow. I tried using the high side and the low side under my neck. Both gave me headaches. I ended up getting a similar pillow for a fraction of the price. Pretty disappointed.
I have cervical spine fusion and this is the only pillow I can sleep with. I have used one for ten years and this is the second one I have purchased. I recommend it to anyone who has a neck problem.
I wanted to love this pillow but the smell was horrible even after letting it sit for 4+ days to air out. The pillow itself was just ok. Not as comfortable as I was hoping for .
