You’ll Sleep Cooler On The Very First Night!
The CloudCool Comforter combines the instant cool-to-touch sensation of Arctic Silk with the plush comfort of CloudKnit, filled with Naia™ air-channel fill that actively pulls body heat away as you sleep. Just pure, passive cooling built into every thread.
YOU KNOW THIS FEELING
Don't Choose Between Staying Cool & Being Comfortable
Every night, it's the same cycle. You crawl into bed exhausted. You pull up the comforter. And within 20 minutes... your body starts overheating.
The fill in regular comforters retains heat instead of cooling down.
But the CloudCool Comforter breaks this cycle with the Dual-Layer System.
Arctic Silk pulls heat away on contact.
The Naia™ fill has built-in air channels continuously circulates that heat out of your microclimate.
And CloudKnit provides the plush, weighted comfort that makes you feel held without trapping warmth.
The result? Your body reaches the temperature it needs to stay in deep, restorative sleep. All. Night. Long.
GET A FULL NIGHT’S REST AND…
Wake Up Refreshed & Ready Every Day
Most comforters, even the expensive ones, trap heat and humidity around your body, triggering night sweats and preventing the deep, restorative sleep your body craves.
When you switch to the CloudCool™ Comforter, everything changes. Your body stays at the perfect temperature all night, moisture is actively wicked away, and you finally get the deep, healing sleep you've been missing.
Enjoy perfect sleep, without night sweats and overheating, simply by switching your comforter to CloudCool™!

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 Naia™ 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 Naia™ 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 Naia™ 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
Care
Fully machine-washable and dryer-safe, no cover needed, no extra steps.

Q:
What makes CloudAlign different?
A:
Unlike mass-produced pillows that are designed for looks and the appearance of comfort, CloudAlign was actually designed by chiropractors to support proper sleep.
These days, we know that people sleep in many different positions… but our pillows simply haven’t changed. We expect the same flat, barely-soft rectangle to support us no matter how we sleep. That simply doesn’t work, and it leads to all sorts of problems: Neck pain, exhaustion, poor sleep, sleep apnea, snoring, and more.
CloudAlign fixes all these problems by creating a single pillow that works for EVERY type of sleeper. Try it for one night and you’ll see why thousands of people have already switched and aren’t looking back!
Q:
How quickly will I notice a difference in my sleep?
A:
In most cases, right away! Many people feel the difference from night one – you'll instantly notice how the 3-zone contour cradles your head, neck, and shoulders compared to a flat pillow. The real transformation happens over the first week as your body adapts to proper spinal alignment and your muscles stop straining during sleep. That's when you'll wake up without the usual stiffness, neck pain, or that "slept wrong" feeling.
Q:
How many should I order?
A:
We recommend ordering two pillows to ensure that you always maintain perfect sleep quality. While you only need one pillow at a time, most customers find that it’s great to have a backup so you never go a night without it. This is helpful to keep stress low on laundry day, and it also saves you a bunch of money on shipping costs. We also offer discounts on bulk orders, and it makes a great gift!
Q:
How do I wash it?
A:
It’s easy! The outer cover is fully removable and machine washable, so it simply goes in with the rest of your laundry. Just unzip it, toss it in the wash, and dry on low heat. The inner foam core is antimicrobial and does not need to be washed – simply spot clean if necessary.
Q:
How do the three zones actually help me sleep better?
A:
The zones are designed to support each part of your upper body the way it needs it most. The center cradles your head so it stays in line with your spine. The neck zone keeps your neck at a healthy angle to prevent stiffness. And the side sleeper zone cushions your shoulder and arm so you're not waking up with numbness or pressure pain. Whether you stay in one position or move during the night, the zones work together to keep your spine aligned and your muscles relaxed.
Q:
What if I try it and don't like it?
A:
No problem! You have 30 nights to try CloudAlign in your own bed. If it's not the best sleep you've had, just send it back for a full refund – no questions, no hassle. We make returns simple so you're never stuck with something that doesn't work for you.
Q:
What's the real difference between the two heights, and how do I know which one I need?
A:
Think of the SwitchFit™ Dual-Height System like having two custom pillows in one. One side is 3.5" high for a softer, lower loft – ideal for back and stomach sleepers or anyone who prefers less elevation. The other side is 4.3" high for extra lift – perfect for side sleepers or anyone who needs more neck support. You can try both sides on your first night to see which feels better, and switch any time your needs change.
Q:
Will it go flat or lose support after a few weeks?
A:
No. CloudAlign is built with proprietary CloudSoft™ shape-retaining memory foam, which means it springs back to its original shape every morning, even after years of use. No lumps, no collapsing, no endless fluffing. It's designed to feel just as supportive on night 300 as it does on night one!
Q:
Why did you work with chiropractors to create CloudAlign?
A:
Most pillows are designed by manufacturers focused on cost-cutting, not sleep science. We collaborated with licensed chiropractors because they're the only medical professionals who spend their entire careers studying spinal alignment and neck positioning. While other doctors treat symptoms after damage is done, chiropractors understand exactly how your head, neck, and spine need to be positioned during sleep to prevent problems before they start.
Q:
Will I have to pay any additional customs, duties or VAT fees when I receive my order?
A:
Depending on your country, it is possible that you will be charged one or more of these fees when you receive your order.
Please note that all international orders are charged in US dollars. International charges are based on the standard exchange rates between your currency and the US dollar at the time of purchase or refund.
Q:
Will you notify me by email when my order has shipped?
A:
Yes, we will send an invoice by email when your order has been placed and another when your order has been shipped.
If you can not find our emails in your normal inbox, it is worth checking in your spam or junk mail folder.
Q:
When can I expect my order?
A:
FAST! We ship all orders within 24-48 hours of receiving them! On average our product is delivered within 3-5 business days in the United States. International shipping times will vary depending on country/customs etc.
