We recently ordered the memory foam pillows which are very good and the hybrid ones were launched so we ordered one as still within our 30 days on the other pillows. We both tried it for a couple of nights and found it to be better so ordered a 2nd one and returned the memory foam ones, received full refund on previous purchase great service. These pillows are very comfy and wife has noticed I snore less maybe because haven't got two pillows now and just the Hybrid Bamboo Pillow which is all I need.
