The pillows I bought were supposed to support our necks and keep us cool through the night. it was only cool when you first lay on the pillow but was never comfortable under out heads. The pillows are too bulky and I thought we were getting memory foams pillows but instead got alot of cut up foam in small pieces inside the pillow. I would ask for my money back if we had not already spent a month just trying to adjust to the pillow itself.
