Is the Sleep Relief pillow material sensitive to temperature?
The Sleep Relief pillow is temperature sensitive, so environmental temperatures may affect the feel of your pillow. Very warm and humid weather may make the mattress feel very soft, while very cold weather may render the mattress somewhat firmer. If you feel the pillow is too firm, try lying your head on the pillows for a few minutes to head it up with your body warmth to increase the responsiveness of memory foam material.
