Beware that small, medium, and large refers to the height of the neck support. The pillow itself is very small. Too small for regular pillow cases. Annoyingly small if you move around at all in the night. I would return it if I could.
I purchased it during the holiday season when they ran the two for one promotion. I thought it was a great deal and would be the solution I needed. I didn't get through the first night because it felt like a rock. I thought it just needed to be broken in. So far that has not worked so the other is still in the box. Unfortunately, I don't think I'll be using it and will keep looking for a solution.
I have purchased 4 Tempurpedic neck pillows, to ensure that I always have one, and to give to my mother who recently pinched a nerve in her neck. This pillow is vital to our spine care and pain relief.
This product is too hard and stuff for me. Also be careful when shopping to notice the size of the pillow, I accidentally got small and it’s an awkward size.
I love the pillow so much, I bought it for a gift for my brother who was having problems with his neck and I also bought one for my husband they both love it. Very comfortable if your a side sleeper or back sleeper. I highly recommend it.
