Nice foam latex pillow. A little thicker than I wanted, but has improved my sleep quality

Just what we were looking for.
Been buying these latex foam pillows for years. Definitely less firm due to it being “extra soft”. Soft and still somewhat supportive. Is not hot either. So glad I can still buy these pillows.
