When I purchased the mypillow for myself, I followed the appropriate sizing chart and got the white medium size. I decided to purchase additional pillows, for my spouse a green level and two pre-teen children were yellow small level.
The first week was great sleep. After that the comfort level decreased. I thought maybe they just needed to be laundered. But we did not notice any more comfort after that.
I now use mine as a body pillow because when I sleep on it, my neck gets numb traveling up the head. I thought maybe I needed a smaller size so I used one of the yellow. I could not get comfortable with this either, felt like not enough support. I am disappointed in the price for the lack of quality.
Additionally, if a pillow gets busted, my dog chewed a corner, it is impossible to clean up.
The particles stick to everything. I could have returned them, but didn't think return shipping charges were worth the hassle.
