We needed new pillows really bad so after reading reviews I decided on the Molecule Gel Foam Pillows. Whether you sleep hot like I do or cold like my fiance these pillows will be perfect for anyone. My fiance sleeps on his back, I sleep on my side but that's not a problem because the @MOLECULE Pillows were designed to satisfy any sleeper. I absolutely love how solid and cool these pillows feel. If by chance the pillows are too high or too firm for your liking you can remove some of the memory foam and make it how you want it. @MOLECULE Pillows were crafted for proper head support, spine alignment, and recovery focused sleep. These pillows are scientifically crafted with support for the ultimate in temperature regulation,adjustability and comfort. I 100% recommend this pillow for back, side, hot and cold sleepers you will not be disappointed.
