Good pillow
Color: Black and White
Very comfortable and good quality. The only reason I am giving it four stars is I wish it was a little bigger. I’m a man and when I wrap my arms around the pillow they aren’t supported fully.

Great pillow
Color: Black and White
This has helped with my neck issues. It does stay cool and keeps me from sweating like my old one, but I do wish it stayed cold.

Perfect pillow
Color: Black and White
I love this pillow! At first I was afraid it was too thick but it's perfect. I have a lot of neck issues and this pillow has stopped all the pain that I used to feel when waking up! The price is good and it works great.
