Attention multi-position sleepers! Get ready for the best sleep of your life. Bedgear's' Impulse Performance(R) Pillow is a dual-chamber pillow that is soft on one side and firm on the other. React(TM) Blend and React(TM) Foam Crown fill provide soft, conforming support for your head, neck and shoulders while an Air-X(R) mesh patch and one air vent on top and bottom keep air flowing to provide cross-ventilation throughout the pillow. A Ver-Tex(TM) instant-cooling cover helps the body to naturally regulate its temperature throughout the night.
