Have gone through 5 or 6 pillows since buying a new mattress in Sept 2023, all have not given enough support to not give me substantial neck and upper back pain.  I sleep in funny positions , toss and turn alot.   Got the essential cooling pillow during my latest shopping trip. This was the only model available . Its far too short in height to support my neck properly.  If I can put my head exactly in the middle of the pillow , the support is great..It is well made, and a good product. its just not good for me   if I move my head much to either side or end of the pillow , ouch ouch, ouch with pain.   Quite expensive to experiment trying to find the right pillow..  Tonight ill probably  try to put something in the pillow case with the pillow to boost its height..  Also, what ever fabric is on the outside of the pillow is very slick, it won't stay in a pillow case ,, im ready to sew the pillow case shut so the pillow stays in the case
