Review (5/5): Super soft, maybe a little too soft.
This is probably the softest, lightest pillow you will lay your head-on. It will take some getting used to the softness of the pillow because it will feel like your head is sleeping on a piece of cloth filled with clouds. This is good and bad for some people, some say it may be a little too soft because there is very little firmness to it, but after about a week It felt completely natural to me.
If you do purchase this pillow I recommend that you also buy a second firmer pillow to put under it, along with some type of fabric freshener. Since I tend to sweat at night my pillow easily started to smell a bit.
I can't really say whether it helps with neck pain because I never really had neck pain.
