I bought these pillows to go along with my new memory foam mattress. At first these pillows were great. Awesome comfort and great neck and head support. After about a month or so, these pillows started to, for lack of a better term, de-fluff. They started to get really painful and awkward to sleep on. I'm the kind of sleeper where my arm is up and under the pillow. These pillows do nothing to support an arm sleeper. I would probably get more comfort with just my bare arm. I really couldn't recommend these pillows because they don't last as long as you would expect them to. It only takes about a month, maybe less, to "de-fluff." Granted they are not bad pillows at all, maybe more suited for kids than adults. If you want to get these pillows for your kids, they are great. For adults, they will only last a very short while before you're looking for something more comfortable to sleep on.
