First off, I bought this because I have neck pain with my normal pillows. Second, i bought this because it said it was a king-size pillow. That is not true. I have a king-size bed with pillows, and i measured this neck pillow and 2 1/2 shorter, so definitely not king size. The first night, my neck didn't hurt, but my spine did. I find it comfortable, but flat. I am a side sleeper, right mainly.
It should be lowered in price due to size.
The cover can be removed from it to be washed. One side is higher than the other for neck preference. Overall, it's not bad, but not worth the money. I may send my back because it's not a king size. That was misleading, to be honest.
False advertising beware not king size.
