"I love these pillows and I receive a lot of deserving rest and comfort from them! I always purchase these pillows because they’re so very comfortable and supportive too! The effects I receive are amazing for my body. The representative, a very nice lady who I spoke with on the phone was extremely nice and helpful too! Thanks Slumber Cloud for your service again."
"Great pillow"
"Initially, I was pleased with the pillow but about 75 days after purchase the pillow lost all of its firmness and the filling started to get lumpy. I'm past the window of being able to request a return so I figured I'd at least warn other potential buyers."
"Finally found an incredibly comfortable pillow! I have been hunting for a pillow and wasting a lot of money and time trying to find one. I got the pillow based on stomach sleeper recommendations, and I’m so glad I did. It is the most comfortable pillow I’ve ever had. Regarding coolness, it’s not like WOW, this is frosty, BUT, it doesn’t get hot or retain heat. It’s VERY comfortable (I use a pillowcase). It does have an odd smell at first, I washed it and the smell is not noticeable now. I recommend this pillow, it’s simply wonderful. In fact, it’s a pillow that I’ll take when I travel because it’s just THAT cozy."
"Bought a soft. It's comfortable but is not cool at all. Very disappointing. Searching for another option"
"Simply amazing!!"
"I tried four cooling pillows and Slumber Cloud's was the best. It was the only pillow that kept me cool enough to sleep throughout the night. It doesn't retain heat like other pillows."
"It’s hard to explain how luxurious these pillows actually are. They are so generous in size and completely fill up any of my king size pillow cases. They are dense yet soft. I’ve never enjoyed a pillow more. Definitely don’t feel as if they get warm at all which I so appreciate as I was always flipping my other pillows from front to back throughout the night! Would buy these again and again."
"my son used to need an ice pack under his pillow every night and would flip it constantly to keep it cool but this has been a wonderful change. He doesn't need the ice pack anymore and rarely flips it (more so out of habit). We are very happy with this product"
"Best pillows! I have purchased about every pillow on the market and disliked them all. These keep my head cool at night and alleviate my neck pain. I have to sleep with two pillows and these stack nicely."
