Seems to be good quality for the little time Iâ€™ve had them. They do not work for me as I thought they would though. I need thinner pillows for stomach/side like these but, they actually are pretty puffy. They will sink in for a lower pillow with weight but, unless you like to sleep with your nostrils breathing into the pillow, you have to sleep on the edge of it and/or fold it so your breathing isnâ€™t obstructed.
I also sleep with my arm under the pillow and if you do this, it sinks far enough down where your ear will start hurting from pressure against your arm. I gave them to my brother in law to try out.
