On first impressions, the hybrid memory foam pillow was great. A soft case covering what appeared to be a “deformable” (memory foam) yet supportive pillow. The excitement however waned over subsequent weeks. The pillow was simply too high, and unless you have a really heavy head, it does not depress sufficiently, resulting in unwelcome strain on the neck (excessive forward flexion when sleeping on the back, and towards the opposite shoulder when sleeping on the side). Basically, the hybrid pillow forced the spine to be curved at the neck/upper back region throughout the night. Not quite the “ideal” spinal alignment one hopes for when desiring a restful undisturbed sleep. Compared with traditionally shaped memory foam pillows, the panda hybrid pillow lacked an arched neck support. I was interested in giving this a go as the reviews were stellar, but clearly this was not one for me. The lack of a neck arch combined with the overly high pillow meant that any curving of the neck was further exacerbated. This pillow isn’t quite a one-size-fits-all, and given the difficulty with returning the item, is not one I would recommend for “trying out”. Additionally, the advertised hybrid system did not result in a cooler surface to sleep on. Certainly, it was neither warmer nor cooler compared with my regular memory foam pillow. It might not be worth the added cost over the non-hybrid version if this is the feature you’re keen on. Overall, if you are prone to neck problems, and require a specific “fit” in a pillow, I wouldn’t recommend this unless you’ve already tried it previously and know for certain it will work for you. I wanted to love this pillow, and required a replacement for my old memory foam, but alas, this was not meant to be, and not the “fuss-free” breakup as advertised by Panda.
