It's fine
Size: Ultra Slim (2.75-Inch Height), Color: Blue
I got this because it was recommended for stomach and side sleeping. The pillow itself is luxury so soft. It isn't the pillows fault but when I sleep on my sides I sleep on my arms and my neck pain hasn't subsided at all. It's been about four nights so far. I ordered one for my husband also cause he likes flat pillows and he absolutely loves it. If it changes for me I'll update.
