They are huge and very fluffy queen size pillows, and they’re so comfortable. I’m actually laying on one right now.

Helps you get a good night's rest
Color: Blue, Size: Queen Size Set of 2
These are my favorite pillows. I've had so much neck pain and headaches in the morning. This all stopped once I started using them. They hold up their shape and seem like they are good quality. My husband kept trying to steal my pillow, so I had to order him his own. You won't be disappointed in these pillows, and you'll get much better sleep.

Very soft!
Color: Blue, Size: Queen Size Set of 2
I like the softness of these pillows. They are too bulky for me but my husband loves his. I’ve been using a flat pillow for too long. I may just need to adjust to it.

BUY THEM NOW!! the search is OVER! 🥳
Color: Blue, Size: Queen Size Set of 2, Color: Blue, Size: Queen Size Set of 2
pillow whore here 🤭 and I very rarely find anything worth writing a 5 star review for but let me just save you the time of searching anymore for the PERFECT pillow!!! BUY THEM! 😍 I promise you will NOT be disappointed!! I have spend thousands on pillows over the years, trying to find the perfect pillows... As someone who suffers from debilitating chronic pain and who has had multiple neck and back surgeries I'm very particular about pillows & have such a hard time finding one's that are comfortable, not too hard, not too soft but also offer great support. I FINALLY found them 🥹 and my hubby is Italian and stays hot but gets even hotter when he sleeps so finding an authentic cooling pillow has seemed impossible UNTIL now!! Just wow!! Now Im adding more to my cart while they are still 70% off 🥳🤩
