Wow! I’m so impressed! This is the best little cooling pillow! I use it on a daily basis, I only wish I had found it sooner! I suffer from night sweats and this pillow has been a big game changer! Perfect amount of firmness and comfort and not overly thick, just perfect! Wonderful value for the money! No odor!

Great travel pillow!

Color: White & Light Blue, Size: M - 18 x 13 Inch

This pillow is a blessing! Very comfortable, easy to fold, easy to travel with. Just finished a trip to Hawaii and so I can honestly say that I used and I highly recommend it! Ended up having to share it with my 4 year old grandson, so I will be ordering another. 😁

It works! Quality pillow.

Size: Standard (1 Count), Color: Original White (Cooling)

This does actually provide a cooling effect, and it's very comfortable! The accompanying literature is helpful too. I believe this to be a quality pillow for the price.
