[This review was collected as part of a promotion.] When I first received this pillow, I first noted how heavy it was. Unzipping the washable cover, I saw the memory foam is cut into pieces. I tend to twist and move my pillow during sleep but found I can't do so with this one. My head sunk in the middle and the sides puffed out. The cooling effect was not there nor the gel aspect. The pillow is fluffy while I prefer something that lays flatter. The pillow does not work for me but may work for someone who prefers fullness.

[This review was collected as part of a promotion.] I am always trying to look for the unicorn pillow and these are pretty close to that! I really like that shredded foam stuffing and it is even better that you can customize who full or flat you want the pillow since there is a zipper and you can remove the filling. It does a pretty good job staying cool too.

[This review was collected as part of a promotion.] The pillow is great! It's firm but, not hard it's really squishy! The fabric feels soft, I didn't really feel “ cooler” but it is super comfy. I love that it's machine washable! Just toss it in the wash on cold and dry for 2 hours easy peasy!

[This review was collected as part of a promotion.] These pillows are very comfortable. They do have a cooling effect, and they seem very form-fitting. The cradle your head. They are a standard size so if you want a pretty case on them it is easy to fit.

[This review was collected as part of a promotion.] The Serta 2pk Cluster Pillow has been working pretty well. They are comfy as that additional pillow. Depending on your preference this might be the right primary pillow but its definitely great as that additional pillow for extra comfort and support.

[This review was collected as part of a promotion.] These pillows are just amazing! I have night sweats super bad due to medically induced menopause and for the first time ever…These pillows keep u from soaking your hair/ neckline from night sweats! I was so happy to see they actually work! They are very thick and quite dense they are very supportive but very cozy! I highly recommend!

[This review was collected as part of a promotion.] This pillow worked well for me as a side sleeper. Initially, it did have its cooling effects as it advertised and I believe it did have "memory." The only downside I would say was that it also had a dense, heavy feeling that I was not a fan of.

[This review was collected as part of a promotion.] I was having issues finding a good pillow, the last set i brought went flat in a couple of weeks so when i get this Serta Cluster pillows i did not have high hopes, well i was happily surprised with the quality! It's been a month and a half and my pillows are so fluffy but at the same time they hold my head nice. Im very happy with the quality.

[This review was collected as part of a promotion.] Have you ever wanted to sleep on a rock that doesn't hurt your head? Well, I have. This is the firmest pillow I have ever used. It's glorious. If you're looking for an extra firm pillow, give these a try.

[This review was collected as part of a promotion.] These pillows are great for the bedroom. We use 2 of these and 2 other fluffy (down) style. I feel like that with these two combinations it is the best way to experience relaxing sleep all night. I put the memory gel pillow at the bottom and the down version on top. The quality of the materials is very very nice and the plush effect you get is also very premium. Highly recommended!
