I have a 15cm high Tempur pillow ORIGINAL QUEEN XL, and am very satisfied. I actually have narrow shoulders and got me for years not married to this cushion height, because it in the shop always said that this pillow is much too high for me. I am glad to have tried it. I do not give her back. Also on the hardness of the pad, it is no problem. By body heat, there are slightly and adapts well, even if the ambient temperature is slightly lower, ie the bedroom in the winter's cold. I can only recommend this pillow. I've tried so many pillows, and finally, after years of what you wanted.
