I tried using this pillow
I tried using this pillow over 2 nights and I find that the 3D mesh filling is simply too firm. It does not have any flexibility to conform or "hug" the head. After laying my head on the pillow, i can feel pressure slowly building at the back of my head after a few minutes, as if I'm laying on a yoga block. The experience is uncomfortable and not conducive for sleeping. My partner tried it too, and had the same conclusion. The only pro I notice is this pillow does not trap as much heat as my form-pillow.
