Love them!
Color: White-cooling Basic, Size: Queen(Pack of 2)
Love them! After 10 years with our MyPillows, they finally lost their fluff. The reviews I read of the MyPillows of today were not good; they didn’t have as much filling as they used to. These pillows remind me of how fluffy our new MyPillows were 10 years ago!! You sink right into them and can mush them however and they stay. These are way cheaper than the Coop and it’s the same concept; add or remove the filling as needed. The cooling side is a huge plus too! You won’t be disappointed with these pillows!

Best Pillow Ever
Size: Queen(Pack of 2)
I am absolutely obsessed with these pillows! They have the perfect balance of firmness and softness, providing amazing support for my head and neck. I've never slept better, and I can honestly say I'd order more in a heartbeat. These pillows are a game-changer for my sleep quality. I highly recommend them to anyone looking for the ultimate comfort.

Worth it!
Size: Queen(Pack of 2)
These pillows are amazing and very soft and comfortable. They came nicely packaged and I let them sit out for just a few hours before using them and that was plenty of time! They come with the cooling cover and fit a standard queen sized pillowcase. The material expands well and does not have any weird smells. 10/10 well worth the price.

Miracle pillow
Size: Standard(Pack of 2)
Best pillow I’ve ever had. I have been using this since December 2024 and it still hasn’t gotten flat. It is amazingly comfortable and solves all my neck issues for a side sleeper. My head never gets hot either. I’ve recommended this to my friends and they’ve had success with it as well.

Really wanted to love these
Size: Queen(Pack of 2)
I really wanted to love these but they gave me a stiff neck. I haven't slept with a pillow since buying these. They are firm except where you lay your head. It just deflates there. I expected it to sink in to match the curve of my neck but it was more than I could handle. My head ended up in a valley between the two ends of the pillow. The price was good, zipper worked fine, it looks as advertised and the pillows are good quality. The cooling part works, its just not what I needed.
