You can feel this by just placing your hand on the pillow. It really stays cool. It is firm and I prefer this, along with the thickness, for side sleeping.
I use the memory gel foam GhostPillow for my main pillow. I use the faux GhostPillow for when I roll to my side then I throw my arm over it. I basically hug it it while I sleep. These two pillows are great for cpap users too.
When I purchased my new mattress I also got a two pack of the GhostPillow Shredded pillows. These are very comfortable and offer a perfect amount of support . They make an amazing difference on my level of comfort at night.
This is seriously the best ever. I’m a HOT sleeper. I struggle...... and I’ve tried so many pillows in all price ranges and ding ding ding this is the one. It’s smushy but firm enough to cradle my neck. It stays cool. It’s the first pillow I simply do not fight. And my sleep has truly improved. I love it. Going to ge purchasing a second one.
