Query: Good for about 3 months

After 3 months this pillow DEFINITELY let me down. Unlike the other "5 star review" this pillow took about 1 week to fully break in. However after 2 months the pillow started to soften. I have just completed a 90 day trial and would definitely return it if possible.DO NO BUY THIS PILLOW UNLESS YOU ARE COMFORTABLE WITH A FLAT PILLOW
