What Customers Say About It

On a popular consumer website the pillow has over one thousand positive reviews. Most customers found the balance between softness and firm support ideal and it helped them to sleep comfortably throughout the night. A majority of reviews cited the benefits of the pillow that has kept them cool and warm exactly when their temperatures need these most.

The Iso-Cool Memory Foam Pillow’s regulatory technology seems to automatically stop coolness or warmth after reaching the appropriate body temperature, which is saying a lot, as far as customers as concerned. Those who sleep on their back and sides are especially benefited by this pillow.

As to the “con” of a sore neck, this would seem as more of an exception rather than the rule since there were relatively few customers who experienced sore necks from use of the Iso-Cool pillow. As to the loss of its firmness after six months, this may be an issue that involves more of how customers used their pillows more than the quality of the pillow itself.

As to the faint odor, it may be the result of having been compressed for packing and eventual shipment. Customer reviews that reported this odor may be smell-sensitive, although the kind of odor was not described by any customer as having been of the foul kind. Still, this issue must be addressed by Sleep Better ASAP since it comes up regularly from reviews on other websites.


There is no doubt that favorable reviews of the pillow far outweigh those that are not. As to the issue of losing support for the neck or head after several months of use, you can always use the 15-year warranty and ask for a replacement. As to the issue of odor, airing the pillow out for a few days have worked for other customers as per their reviews.

The Iso-Cool Memory Foam Pillow is a quality product that you should get if you have support issues with both your head and your neck. And those who have body temperature changes quite often, then this pillow is your versatile sleep companion that will give you warmth and cool as your body temperature dictates.

For all of its features, the Iso-Cool has the best price for a pillow in its class.
