I slept on one of these pillows for a week, and it became half as thick as the one I hadn't used. In other words it went flat as bad as a cheap walmart pillow.

Waited 3 months before doing this review....pillows are slick, you will end up chasing your pillow cases. Even my percale cases keep sliding off. I did get "envelope" pillowcases to keep the pillows in.There is a chemical smell when you take the zipper case off of it. Very cheap scratchy material inside. (Not sure what it is.) The pillows did stay somewhat cool. I would not purchase these again.

The pillows were flat after a week and $25 for these pillows definitely not worth it. Very upset with the price and quality. I thought this brand would be great.

There is nothing good to say about these pillows!! I have purchased many cheap pillows like these for a lot less money. Pass them by not worth taking home.

These pillows do produce a nice cooling effect but their durability is suspect. We purchased two sets of these pillows, one set is flat as a pancake already and the other lumpy and uncomfortable. When we first purchased these pillows, they were not only cool but also comfortable but these attributes didn't last long.

A pillow is supposed to help align your head and neck. These pillows are very thin. Sleeping with my head on my shoulder with my arm up is more comfortable than using these pillows. You would need to put both pillows in one case to have enough height.

If you like a very flat pillow this is for you

This pillow lacks form and function as it soft and head sinks instead of being supported

Comfortable, however pillowcase slips off! I am going to try sewing buttons on my pillow cases!

Cooling but go flat literally overnight. Haven't had them a week and already don't like them. Good price if you like flat pillows or use them for shams or guests that you don't want to stay too long. Ha
