Pretty nice blanket
First off I have to say that this is not exactly a cooling blanket. It is true that when you first get under it, it does feel cool. Shortly thereafter though, wherever the blanket makes contact with you it warms up to your body temperature, so it doesn’t remain cool. Still, I just moved my foot to a different area and hit a cool pocket, so it has its moments. I have to say I really like the weight of this blanket. It’s so hard to find a good blanket, that is not that thick, It is thin, which is exactly what I was looking for since I live in Florida. One side of the blanket is the “cooling“ side which is plain gray, and on the other side is a gray and white striped pattern. I’m not really crazy about the pattern to be honest. I wish this blanket came in more colors or patterns. The blanket fit my queen bed nicely - not too big or too small. For what it is, I’m not really sure I would say it’s good value for the money, but I do like this blanket.

Surprisingly, effective cooling blanket
When I first saw this cooling blanket available, I grabbed one right away. I had purchased a cooling blanket for my grandfather last summer that was fantastic but very expensive, so I was curious whether this one would actually compare considering the price difference. Right out of the package, I could immediately feel that it was different from a normal comforter. The fabric itself feels noticeably cool when you touch it, which honestly caught me off guard in a good way. The gray version I have features a striped design on one side and a solid gray color on the reverse. I love that it isn’t just plain white like so many cooling blankets tend to be. The pattern adds some visual interest while still matching pretty much any bedroom setup. The fabric is incredibly soft and smooth against the skin. The brand says it’s made with Ice Toweling technology fabric, which supposedly works by absorbing body heat through the fibers’ molecular structure. I’m not totally sure how that works scientifically, but I can definitely tell you the result is real because the blanket does feel cooler when you sleep under it. Something else I appreciate is that despite being silky smooth, it doesn’t constantly slide off the bed. I was expecting it to behave like a satin sheet, but it actually stays in place surprisingly well and its true to size. Cleaning is straightforward. They recommend air drying the blanket to preserve the cooling fibers, which seems like a reasonable precaution. I would probably treat it like a delicate fabric just to keep it in good shape long term. All things considered, I’m really impressed with this blanket. It’s soft, comfortable, genuinely cooling, and a great value compared to some of the pricey alternatives out there. If you tend to overheat while sleeping, this is definitely worth considering.

Not firm.
Color: White, Size: Queen
This mattress topper is not firm. So it doesn’t really fluff up to 3 inches. More like inches. But when you lay on it ,it’s like so soft and comfortable. It makes you feel so cozy. I plan on ordering a second one for more cushion.

Life changing!!
Color: White, Size: Queen
I slept like I've never slept before in several years! I'm diabetic and run hot and cold all night! The mattress topper is truly a game changer! I have a mattress with 4 inch memory foam. I usually sleep about 2-3 hours and then awake 2-3 hours! Last night I didn't sweat or get hot! I'm not one to waste money when I'm already comfortable! This topper is life changing! It's quality is outstanding! And a value is priceless if you sleep and don't keep waking up! It fits my queen bed perfectly. No odor! I love my topper and never knew it would be a game changer!
