ADJUSTFILL TECHNOLOGY
Designed & Recommended by Chiropractors
"I recommend this pillow to anyone who wants the perfect height. It fixes the alignment issue most pillows fail to address."
-Dr. Heim
Adjust To Your Perfect Height!
Only the Mellow Flex combines cloud-soft shredded memory foam with a AdjustFill (ā¢) technology, so you get the exact support your body needs, every single night.
YOUāLL NEVER GO BACK!
Finally Fix the Root Cause of Neck Pain
Most pillows take a "one-size-fits-all" approach. And your neck pays for it. You wake up with a stiff neck or with upper back pain because manufacturers didn't take your height into consideration.
The Mellow Flex breaks this cycle with AdjustFill Technology. You add or remove shredded memory foam until your pillow sits at the exact height your body needs.
The result: a single pillow that works for YOUR body, preventing pain, aches, stiffness, and every classic "pillow problem."
GET A FULL NIGHTāS REST ANDā¦
Sleep In Perfect Harmony With Your Spine
When you switch to the Mellow Flex, everything changes on night one. Your spine stays in perfect alignment. Pressure points disappear. Your muscles finally release.
No more having to adjust the fluff in the middle of the night. Just fill it to your perfect firmness and rest.
Your body gets the deep, restorative sleep it's been missing because you gave it a pillow that was actually built for it.

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 positionsā¦ but our pillows simply havenāt changed. We expect the same flat, barely-soft rectangle to support us no matter how we sleep. That simply doesnāt 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 youāll see why thousands of people have already switched and arenāt 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 ā 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 itās 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:
Itās 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 ā 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 ā 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 SwitchFitā¢ Dual-Height System like having two custom pillows in one. One side is 3.5" high for a softer, lower loft ā ideal for back and stomach sleepers or anyone who prefers less elevation. The other side is 4.3" high for extra lift ā 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 CloudSoftā¢ 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.
