Oversized
Size: Queen (Pack of 2), Color: White
I have chronic neck pain. I am forever buying new pillows. Sometimes I think I found the perfect pillow but then three months later they’re losing their loft. I thought I would give these pillows to try since the stuffing is removable. Now these pillows are really oversized. To the point where I thought that they had sent me king-size pillows but I double checked the packaging and they were Queen. I ended up having to buy king-size pillowcases for them because they just barely fit in the queen size and the pillowcases would always end up pulling back from the edge. So that’s a negative one star there. Now I’ve been sleeping on these pillows for a while and they have held up well. I did end up removing some of the stuffing because it was just too much. I’m a side sleeper and when I use this pillow, it does a good job of keeping my neck in alignment. However, the pillow tends to migrate up as I sleep. Or I tend to slip down off the pillow, either or. So that’s why I’ve removed a second star. Maybe if I removed more stuffing that wouldn’t happen, but then I feel like the loft would be too little. I will say that these provide great support when sitting up in bed reading or watching TV. So would I buy them again? Probably not. Am I going to keep using them? Yes

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.
