I ordered from three different brands that all claimed to have the ‘best’ cooling comforter. The moment I unboxed them, Mellow stood out right away. The quality was obvious. After just a few nights of sleep, there was no question in my mind. This one’s the winner.

FAQ
Will it keep me cool all night?
Yes. The dual-sided design lets you choose Arctic Silk for an instant cool handfeel or CloudKnit for soft, breathable cool. Airflow through the fill helps heat escape so you stay comfortable till morning.
How is this different from other “cooling” comforters?
Most use one fabric and call it a day. Mellow gives you two cooling faces, a built-in shell (no duvet cover), machine-washable construction, and a sustainable fill so it’s cooler, cleaner, and easier to live with.
Is it actually cool-to-the-touch or just “breathable”?
Arctic Silk feels noticeably cool on contact; CloudKnit feels like a premium, t-shirt-soft cool. Flip to the sensation you prefer.
Lightweight means thin. Will it still feel full?
It’s light on heat, full on loft. The airy core keeps a plush, comforter feel without the heavy, trapped warmth.
Do I need a duvet cover?
No. It has a built-in, duvet-style shell, no shifting, no extra layers, no hassle.
Good for night sweats and humid climates?
Yes. The breathable weave and airy fill move heat and moisture away from your body, helping you stay drier and more comfortable.
Can couples with different temps make this work?
Yes, set the comforter with the side you want facing up (Arctic Silk for max chill, CloudKnit for softer cool) and fine-tune with your thermostat or a light layer. It balances comfort without the blanket battles.
Is it safe for sensitive skin?
Absolutely. OEKO-TEX® certified, hypoallergenic, and antibacterial, so it’s gentle on skin and stays fresher between washes.
Is it vegan? How does it compare to down?
It’s 100% vegan—no feathers, no animal by-products. You get cool, breathable loft without down’s heat, allergens, or special-care requirements.
How do I wash it? Will it clump?
Just machine wash and tumble dry, no cover to remove, no dry cleaner. The construction is designed to wash evenly and fluff back up after drying.
Can I use it year-round?
Yes. Use it solo in warmer months, then layer with a sheet or throw when temps drop.
What if I don’t love it?
You’re covered with a 30 day return period and a lifetime warranty sleep on it, stress-free

I’m in love! I can’t sleep without it now Thank you!
I am under the comforter and my cat is laying up against me. We both love the Cloud Cooling Comforter! When it’s on me, I don’t really feel the coolness but it’s so soft that I don’t even mind. I actually sleep with it on the other side because the „non-cooling“ side is even softer. I can feel the coolness when I run my hand over the cooling side—it just doesn’t really cool me down to sleep under it. I didn’t expect a miracle; I have a very hard time regulating my body temperature and feel uncomfortably warm most of the time. The comforter at least doesn’t add to that! I already have a really hard time getting out of bed and the comforter makes it even harder because it’s so soft and cozy.
We love everything mellow has dropped. And this cooling blanket is top tier. Nice and cold on one side and a nice soft plush feeling on the other side for a warmer feeling. I got my son the nightfall color, my mom the pink, and me the midnight. Highly recommend
I purchased this for my husband as we had a blanket divorce and immediately felt it and decided I needed to get one for myself. Now our teenager wants one. Highly recommend if you sleep warm at night!
OMG. I have two of these cooling comforters now, in lavender and navy, and they are LIFESAVERS. It has been extremely hot where I live, and they have kept me sleeping comfortably. The material on the cooling side is unbelievable soft and breathable, so I use that side against my skin and it makes the heat a lot more bearable. It has another softer, warmer side you can flip over to if it's chillier, so it works both ways. I originally bought this in lavender back when there were less colors, and as soon as they dropped a Navy one, I got that, too! I wouldn't sleep good without Mellow, so if you're wondering: YES. GET IT. It keeps you cool in the heat and cozy if it's a little chillier. Nothing has ever felt as refreshing as cozying up with my cooling comforter after a hot day. Best sleep of my life! <33333 Mellow.
It's a mess right now, but we absolutely LOVE this comforter. It's lightweight but still keeps us warm enough. The top is SO cold to the touch and so soft and silky. By far my favorite comforter I've ever had. ❤️
I absolutely love my mellow soft cooling blanket. Us older ladies going through menopause tend to have severe hot flashes. I don’t have those anymore. I stay nice and cool and the blanket is so lightweight but yet it feels like it’s got some substance to it. I would absolutely recommend getting this blanket.
I find it told me stayed cooler, and my dog loves sleeping under it. Keep him cool as well. My boyfriend thinks it’s the best and now we might have to buy him one as well.
Sorry for the bad picture! But this comforter is definitely cooling! I like it & my cats like it. My boyfriend even admitted that he liked it! The color is so pretty & it’s so soft & cool to the touch. I will be buying another one soon.
I love love this blanket. It's light, I can have the cool side or the warm side, which ever I need. I would love to have a throw size for watching movies. Plus I could get a throw size for my dog to have one. I just got the sheets but they only had white. I need colors due to having a dog. I'm sure they will be coming. Love the pillow cases too. Not like the satin ones that fuss up. These don't. I got the pajamas thinking 🤔 they would be out of the same material but it was different material and not as comfortable.
The shipping on this order had a few issues but the customer service team were awesome and checked in with me everyday until it came! Amazing contact and effort from them. The blanket itself is awesome I love it! I also have the cloud comforter but that was way to hot for the summer. The cooling blanket is very thin but it's perfect for hot summer nights and the feel is so smooth and soft!
I LOVE my comforter! It is so light weight & feels like a cloud when sleeping. I am a hot sleeper & this cools me right down. It washes very well & is super comfy! I am going to get the larger comforter for winter 🙂
Love this blanket! I bought it to use as a lighter blanket in the summer and to see how the cooling side would be. Best thing ever, it feels so soft.I love it and I can't stop saying it! My kids like it too. Will definitely buy more of this.
Very nice comforter! I actually just bought one for my daughter as well! Well worth the price. The one side is soft and warm but not hot, like a soft sheet the other side is a soft silky feel with cooling touch! It’s an amazing combination. I only sleep with this and if I get a little warm I just lay my legs on the cold side and cool off quickly then back under I go! Highly recommend. I live in Florida and it’s difficult to be comfortable. I want a blanket but usually am too hot. This is literally perfect.
As you can see, I got my new Navy and it matches my bedding perfectly….
I first tried this when I visited my girlfriend in Texas and she had ordered one for my guestroom and one for herself, and one for her husband… I fell in love with the texture of this blanket, and it’s all I needed to sleep, especially in Texas!! I love that it has two sides because I usually run cold-this is the blanket that I use and drag around the house to the sofa to my recliner wherever I am… it is my favorite! I really want to try a pillow because I’m having some bad headaches that they think are related to my neck, but I’m not sure which one to try… suggestions?
Thank you so much for making this and! Thank you to my friend Jodi Niemann in Texas for getting me hooked on these!
I’ve had my comfy cool 😎 breeze comforter for a couple weeks now and it’s incredible! My fiancé is insisting on one for her place in Kansas City! I have never had anything like it before and it’s crazy cozy and breathable yet I’m warm and cool comfortable at the same time! Crazy! Thanks 🙏 for a great experience! Greg McGivern, Topeka, Kansas
I followed the wash instructions 100%. I even bought a huge washer and dryer set for this blanket. On the very first wash, the corner tore in a few spots. I emailed customer about this and they continued to accuse me of washing it wrong, washing it with other laundry, and not using a larger washer and dryer. They refused to take accountability and just continued to dismiss me. I have recommended them previous to washing. I won’t anymore. The blanket also has a bad pilling issue.
I’m a really hot sleeper so this has been a game changer!! It really cools me down and helps my anxiety at night. It’s really smooth too! Love how lightweight it is. The color is really pretty too!! The lightening is just hard to get it for pictures. Highly recommend!!!
Silky Arctic Silk for instant chill, plush CloudKnit for cozy cool flip to the side that feels just right.
