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!

heavenly.
Color: White, Size: Queen (Pack of 2), Color: White, Size: Queen (Pack of 2)
UGH, i'm so obsessed with these pillows!! they're so comfortable, adjustable, AND perfect in general. they're so fluffy when you get them, but you can take out as much of the memory foam as you'd want. what i really like about these pillows is, the ability to unzip the pillow & wash when desired (please read the instructions!) 💫. i sleep a lottt better compared to my other pillows, i highly recommend to get you some of these 🙂↕️✨✨. i'm not sure about a "cooling effect" since i have a pillow case over them, but they stay a neutral temperature where it's comfortable. i'm definitely going to back soon to buy the body pillow and a case (or two!) to revive old pillows (which i also love!). they come in a pair, so it's HIGHLY worth it, get them rnnn!!

Shocked
Color: White, Size: Queen (Pack of 2)
I'm really bougie when it comes to pillows. I've never spent less than $50 on a pillow. I'm a side sleeper and like firm support, but also want something soft. I almost ordered the really pricey pillows on Amazon, but was turned off by all the odor complaints. I needed something quick to at least hold me over until I could get exactly what I want, so I took a shot with this pillow with the plan of it being a temporary fix. However, this pillow turned out to be exactly what I was looking for. The first time I laid on it I was skeptical. It had support, but felt like it may have been too soft. It took a bit to get accustomed to, but by the second night I knew this is the pillow. No chemical odors, it's quality at a low cost. I figured this pillow would've been quickly replaced and put into the leg pillow rotation, but it is shockingly a really great pillow. It is not lumpy, stays way cooler than standard or shredded memory foam and is comfy. Hopefully it holds up for a long time. I've paid triple what these 2 pillows cost for a single pillow that isn't as good.

Favorite pillows
Color: White, Size: Queen (Pack of 2)
These pillows are amazing! They are huge and plush but you can change that if you prefer. I really like that the outside cover can be washed and is also filled. It held up great in the washer and dryer. I just followed the directions on the tag. Great price for the quality and look very nice and fluffed on the bed.

Good option
Color: White, Size: Body(Pack of 1)
I’ve been using the ACCURATEX Full Body Pillow for Adults – Hybrid Shredded Memory Foam for a few weeks now, and overall I’m really happy with it. The blend of shredded memory foam gives it a firm, supportive feel, but what I love most is that you can adjust the filling to get the exact firmness you want. Whether you prefer something more structured or slightly softer, it’s easy to customize by adding or removing foam.
Comfort-wise, it’s definitely a step up from standard body pillows. It keeps its shape throughout the night and offers great support for side sleeping. That said, it is a bit firmer out of the box than I expected, which is why I’m giving it 4 stars instead of 5.
If you’re looking for a body pillow that won’t go flat and lets you tweak the feel to your liking, this one is a solid choice.
