no thank you
Color: Blue, Size: Queen Size Set of 2
while they look great, they are not soft. I can not sleep with them. Woke with a headache.

Loved the pillows
Color: Blue, Size: Queen Size Set of 2
I don’t get paid for reviews so if you want a real one here ya go ….
These pillows are great in my opinion. They came vacuum sealed and popped right up “ big and fluffy” immediately, as in big enough I wasn’t sure they would fit in my pillow cases.
I used them last night and even though they are full, big and fluffy they still smashed down to a proper size when I laid my head down. First night in a long time I did wake up with a headache. I was extremely happy with these pillows.
Now cooling ….I didn’t really find a difference from a reg pillow but, that again just could be me. Hope this helps

Heavenly Sleep Upgrade – DIORIS Pillows Are a Dream Come True!
I’ve finally found the perfect pillows! The DIORIS Queen Pillows Set of 2 has completely transformed my sleep experience. From the moment I laid my head down, I felt like I was at a luxury hotel — but right in my own bedroom!
These pillows strike the ideal balance between softness and support. The premium down alternative filling cradles the head and neck gently, yet offers just the right amount of firmness. Whether I sleep on my side, back, or stomach, these pillows adapt perfectly and keep me comfortable all night long.
The slow-rebound, breathable fiberfill is a game changer. It stays cool, supports proper posture, and even helps reduce neck pain — something I’ve struggled with for years. I wake up feeling refreshed and ache-free, which is priceless.

Wonderful
Size: Cooling Queen, Size: Cooling Queen
I absolutely love these pillows From the very first night, I could feel the difference. They are incredibly comfortable, soft, and still provide great support for my neck and head. Plus, the modern design makes my bed look so much cleaner and more elegant. The fabric feels high quality, and the pillows keep their shape really well. I genuinely feel like I’m sleeping better since I started using them. Great value for the price, and I would definitely buy them again. Highly recommend
