Great cooling pillow
The Casper Sleep Essential Cooling Foam Pillow has completely elevated my sleep experience! From the moment I first rested my head on it, I could tell this pillow was something special — soft and comfortable yet supportive in all the right places. What I love most is how cool it stays throughout the night. The breathable foam doesn’t trap heat like traditional pillows, so I wake up feeling refreshed rather than warm or sweaty. The balance of plushness and structure is perfect — it cushions your head and neck without flattening out, which has helped improve my overall comfort and sleep alignment. The pillow also adapts well to different sleeping positions, whether I’m on my back, side, or stomach. It has a high-quality feel and holds its shape night after night without getting lumpy or compressed. Easy to care for and durable, this pillow is worth every penny. If you’re looking for a cool, comfortable, and supportive pillow that genuinely helps you sleep better, the Casper Sleep Essential Cooling Foam Pillow is a fantastic choice! 😴🛏️💤

The BEST pillow
This is THE pillow! So firm and yet soft. A little too thick but it absolutely molds to you and it becomes super comfy. I’ve only had it for one night and it was the best for side sleeping!!! I sleep so well and my neck felt so supported and relaxed. I’ve had chronic neck issues for years and gone through tons of pillows and finally found the one. It was good to use right out of the box, it is cool and there is no smell like others. Material is firm and soft and feels high quality. I shall see how the firmness holds over time but so far for a one time use I am super impressed.

Essential Cooling Pillow: Not firm or resilient, your head sinks into it
I don't know why they have different pillows all under the same listing because it lumps the reviews together. Some of the pillows are listed as down alternative and soft while some are foam and firm so it makes the reviews incorrect and inconsistent. This review is for the Essential Cooling Pillow. First, The listing is incorrect it is not 2 inches thick, it is 5.5 inches thick. I caught this before ordering it because I wouldn't be buying a 2 inch thick pillow. Second, The pillow is listed as firm however it is not firm at all. Your head sinks into it about 3 inches, leaving the pillow about 2 inches thick. That isn't firm. If you are looking for a medium soft memory foam pillow with a nice cover at a moderate price, maybe it is for you. It wasn't for me. I ordered firm because I wanted firm.

Comfortable pillow, but cooling effect is more subtle than expected
We picked up these Casper Essential Cooling Foam Pillows during Prime Day to replace our older cooling foam pillows that had started sticking to the pillowcases. The pillows themselves are comfortable and supportive, but the cooling technology isn’t as ‘chill’ as we hoped—there’s a slight cool feel, just not the strong cooling effect we were led to believe from the description. For now they’re fine, and we’re planning to pair them with dedicated cooling pillowcases to see if that helps keep things more comfortable on warm summer nights.

Great
Objective statements: Appears high quality, no loose threads, nice zipper closure. Material is soft. Size is as you would expect. Subjective statements: Very comfortable to sleep with. Great for side sleepers. More firm than fluffy. Material is very comfortable, and does not trap heat as much compared to regular pillows.

Great Quality, Firm Pillow
I am giving this pillow 5 stars, though it did not work for me. I think it will be an excellent find for some who are looking for the qualities this pillow has. First of all, it is excellent quality. It does have a factory smell that I believe will dissipate after a couple days. It is definitely a firm. Like very firm. I am shocked to see people saying this is not a firm pillow. I have been looking for a firm pillow. I have tried 5 so far. They have all been too soft. Then comes this one and somehow it's too hard. I was so bummed. It's also very tall and because it is firm, I didn't sink in far enough into it and it made my neck hurt. I think it'll be awesome for someone else though. I envy that person because this is a great pillow. One thing I want to point out is that in the images for the pillow, it states it is 6 inches. In the product description it says 5 inches. It is in fact 6 inches. I was glad for this at first thinking I maybe wouldn't sink to the bottom. Instead it ended up being too tall. Overall this is a very quality pillow. Firm and supportive. I hope this helps someone in the pillow buying crisis like myself.

Stay far away from this product, it will cost you!
This pillow seems very nice, I thought it was going to be great. However it causes the neck to be lifted up to high which results in a lot of neck, shoulder and middle/upper back pain. Chiropractic care cost my hundreds of dollars but couldn't fix it. All it took was getting a new pillow. I suspected it was the pillow because it started when I changed pillows but because this pillow was so expensive I didn't want to let it go. It would have been much better to lose the $60 pillow than to pay the hundreds for chiropractor to only still have pain.

Wayyyyyy too thick. So disappointed!
This pillow is very firm which I don’t mind and it is definitely cooling. But it is wayyyy too thick for me and I wake up every morning with neck pain. I have to get rid of it. I really like the memory foam but it’s just unbelievably thick and I can’t get comfortable in any position with it. I’m normally a side sleeper for reference.

Great pillow
Worth the wait to get this pillow in Europe. Was available in king size for a good price and is definitely worth it.

Invest in your sleep!
This pillow completely changed the way I sleep. The foam gives just the right amount of support without feeling too firm. It also stays cool through the night which is a big deal for me since I tend to overheat. I used to wake up with a sore neck and now I wake up feeling rested. I didn’t realize how much difference the right pillow could make until I tried this one. If you’re worried about spending so much on a pillow, I’d like to assure you that getting a restful sleep IS worth it!

Supportive pillow, but on the firmer side
This Casper foam pillow feels supportive and well made. It has a firmer feel than a regular soft pillow, which is good if you prefer more neck support or sleep mostly on your side. The cover also feels smooth and comfortable. I like that it keeps its shape better than many basic pillows, and it does not flatten too quickly. The cooling feel is nice at first, although it still depends on the room temperature and how warm you sleep. I gave it 4 stars because it may be too firm or too high for people who like a softer pillow. Overall, it is a good quality pillow if you want firm support and a cleaner, more structured feel.
