First time I have tries a memory foam pillow. Last time I try a memory foam pillow. Tried this one because of firm review and 5 inch thickness. Center is 5 inches thick until you put any weight on it. Instantly compresses to about 2 inches thick. My head was in a little valley with the pillow higher on both sides. Memory foam is warmer than I expected. I had a thin, warm pillow wrapped around my head. Way too soft and thin for a side sleeper.
