GET A FULL NIGHTâS REST
Wake Up Looking & Feeling Rested!
Standard pillowcases (even the "nice" ones) are made of cotton fibers that grab onto your skin as you move in your sleep. That friction is what causes sleep creases.
And while all that friction is happening, your cotton pillowcase is soaking up the serum you applied before bed, the moisturizer you paid $60 for, the face oil that is supposed to work overnight.
When you switch to Mellow, everything changes on night one.
The silk-like surface glides against your skin instead of grabbing it. Sleep creases disappear. Your skincare products stay where you put them. And because of the cooling fiber technology built into every pillowcase, you stop flipping your pillow at 2 AM looking for the cool side.
FOR BEAUTY AND HOT SLEEPERS
Perfect For Every Type of Sleeper
Mellow always feels cool and smooth against your face, no matter how you sleep or how many times you toss and turn at night.
Hot Sleeper â Instantly draws heart away on contact. Keeping your pillow cool and dry while you sleep for a refreshing nightâs rest.
Beauty Sleeper â The same smooth surface lets your hair move freely while you sleep instead of snagging and pulling against rough cotton fibers, so you wake up with less frizz, fewer tangles, and noticeably less breakage over time.
Finally wake up with smoother skin, healthier hair, and a pillow that actually stays cool all night.
LUXURY YOU CAN TRUST
Silk-Like Softness + Cooling Technology
For the first time ever, you donât have to choose between a pillowcase thatâs good for your skin and hair, and one that keeps you cool.
Unlike other pillowcases that use cheap coatings that wash out, FrostWeaveâĸ is a proprietary cooling fiber woven directly into the fabric. This creates a cool-to-the-touch surface that actively pulls heat away from your body, so you stay comfortable all night long.
But itâs not just about cooling. The weave is incredibly fine and smooth.
This allows your skin and hair to glide across the surface, instead of catching and tugging.

Every standard pillowcase on the market was designed the same way, cheap fabric, mass produced, shipped out, and forgotten.
Mellow started from a different question: what if your pillowcase was actually an active part of your beauty and wellness routine? What if, while you were sleeping, your bedding was protecting your skin, preserving your hair, and keeping you cool, instead of working against all three?
The Mellow Cooling Pillowcase is the answer. The FrostWeave (âĸ) isn't just soft fabric with a nice name. It's a purposeful combination of cooling fiber technology and a friction-free surface that has been designed to deliver real, visible results by morning.
This is what beauty sleep is supposed to feel like.

FAQ
Is it really cool to the touch?
Yes. FrostWeaveâĸ fabric uses advanced cooling yarns that instantly draw heat away from your skin. Independent lab tests show it transfers heat up to twice as fast as cotton or silk for a genuinely refreshing feel.
Will it help my skin and hair?
Definitely. The low-friction FrostWeaveâĸ surface glides smoothly against your skin and hair, reducing overnight creases, frizz, and dryness while helping maintain your skinâs natural moisture balance.
Is it safe for sensitive skin?
Yes. The pillowcase is OEKO-TEXÂŽ certified, hypoallergenic, and free of harsh coatings. It feels gentle even on delicate or breakout-prone skin.
Does it stay fresh between washes?
It does. The fabricâs odor-resistant fibers and moisture-control weave keep your pillow feeling clean and dry longer, with less buildup from oils or skincare products.
Is it machine washable?
Absolutely. Wash cold, tumble dry low, and it comes out soft and smooth every time. No special care or delicate cycles required.
How is it different from silk or bamboo pillowcases?
Silk and bamboo can trap heat and require careful washing. FrostWeaveâĸ offers the same smooth, beauty-friendly surface but stays cooler, feels fresher, and is easier to maintain for everyday use.
I bought this thinking it would just feel cool, but itâs way more than that. The fabric actually stays cool all night, and my skin and hair feel amazing in the morning. No creases on my face, no frizz, and it still looks brand new after several washes. It feels like sleeping on a chilled silk cloud.

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 positionsâĻ but our pillows simply havenât changed. We expect the same flat, barely-soft rectangle to support us no matter how we sleep. That simply doesnât 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 youâll see why thousands of people have already switched and arenât 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 â 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 itâs 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:
Itâs 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 â 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 â 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 SwitchFitâĸ Dual-Height System like having two custom pillows in one. One side is 3.5" high for a softer, lower loft â ideal for back and stomach sleepers or anyone who prefers less elevation. The other side is 4.3" high for extra lift â 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 CloudSoftâĸ 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.
