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.

This pillow is very soft and comfortable, and the cool side of the pillowcase works wonderfully.

Perfect Pillow!

Size: Ultra Slim (2.75-Inch Height), Color: Blue

I have spent so much money trying to find the right pillow. As a side sleeper I would always wake up with a stiff neck but not with this pillow! It’s a perfect height and the pillow stays fairly cool. It’s totally my Goldilocks pillow!❤️
