This pillow is a combination of original and foam pillows from Casper.  I have the original casper pillow, and then bought the casper foam pillow.   That pillow was too rigid and I returned it.   When the Hybrid pillow introduced, I decided to try it for the 30 day period.   The hybrid pillow is more comfortable and elevates my head to a comfortable height.   I have been very satsified with this pillow.
