Mellow Sleep | Cloud Cooling Pillowcase

✨ Silky Smooth. Zero Wrinkles. Zero Compromise.

Engineered exclusively for the CloudAlign Pillow, this pillowcase is powered by FrostWeave™ Technology — a fabric so smooth it feels like it was made for sleep (because it was). No bunching, no creasing, no rough seams. Just a perfectly smooth surface from the first night to the hundredth.

❄️ Cool to the Touch. All Night Long.

Most pillowcases warm up within minutes. Ours doesn't. FrostWeave™ actively draws heat away from your skin, keeping the surface cool, fresh, and breathable from the moment your head hits the pillow until your alarm goes off. Hot sleepers, this one's for you.

🌿 Gentle on Skin. Easy to Clean.

Soft enough for sensitive skin, durable enough for the washing machine. Toss it in, pull it out, and it's ready to go — no special care, no fuss. Because taking care of your sleep shouldn't be extra work.

🏨 The Choice of Luxury Hotels & Spas.

The same silky, cooling feel that five-star hotels deliver — now on your pillow, every night. Once you sleep on it, standard pillowcases won't cut it anymore.


  • 1× Mellow Sleep Cooling Pillowcase
  • Available in Standard/Queen and King sizes

  • Compatible with the Cloudalign Pillow (sold separately)

Great Quality and Super Comfortable!

The pillow has a nice balance of softness and support. It feels very comfortable and helps keep my neck in a natural position while sleeping. I've been sleeping much better and waking up without the usual neck stiffness.

Outperformed every expensive pillow I've tried!

After switching to this Mellow pillow, I noticed the difference within one night. My neck feels properly supported and I finally wake up without that sore "slept wrong" feeling. It holds its shape well and doesn't flatten like the others. Easily one of the best pillows I've owned.

Great side sleeper pillow!

This pillow is incredibly comfortable and supportive! Purchased two for my husband and I and could not be happier! Provides great neck and shoulder support without feeling too firm, and I've been waking up with less stiffness. Definitely a great purchase!

No more neck pain!

First night sleeping with it and I have no neck pain. I had been waking up with headaches and my neck, shoulders, and back hurting for a very long time. First night and I didn't toss and turn as much as before. Now I need to look at more products from this company!

In love!!! 😍

FINALLY!!! A pillow worth the wait! I mainly sleep on my side but typically start off on my back and I finally am not having any neck or back issues. It has even helped with my teeth grinding and jaw clenching. I am over the moon happy! Highly recommend!

PLUSH YET SUPPORTIVE!

This pillow has the perfect mix of soft and supportive! It has that "sink in" feeling while still keeping your head and neck supported without constantly drooping off or needing to readjust it in the middle of the night. Super plush while keeping its structure!

Best pillow I've ever bought!

The best pillow I have ever bought. Love how it is always cool. Stuffed the right amount. Any way you flip it — long ways, sideways, or turned over — you'll find the perfect position for your neck and sleep sooo well. A wonderful pillow.

Best pillow you will ever purchase

Purchased one for my wife a couple months ago. Thought the reviews were all hype. The pillow helped with her sleeping and neck pain. Just purchased one for myself. Wish I would have done it sooner. Total game changer with sleeping. Highly recommend.

Comfortable and supportive

My husband and I both purchased this pillow, and we absolutely love it. It's incredibly soft, comfortable, and provides much better neck support than a regular pillow. I've also noticed that I fall asleep faster since switching to it. Would definitely recommend!

This has made a difference for me

I've been using it for 10 days and it has made a big difference in the quality of sleep I'm having. I don't seem to roll around all night looking for a comfortable position. I use the thicker edge under my neck and now primarily sleep on my back. I just go to sleep and wake up in the morning!

Absolutely love it!

It is big, supersoft and honestly way better than the cervical pillow I was originally planning to get. I still support my neck but feels much gentler and looks so much nicer too. Total Upgrade.

Bought 2 for a backup!

Love my pillow case. I actually bought 2 so I have a back up. They are so cooling and fit the cloud pillow perfectly.

Total game-changer!

I absolutely love my baby blue cooling pillowcase! The cooling fabric is a total game-changer. It stays wonderfully crisp and comfortable throughout the night, helping me get a much deeper, more restful sleep. Highly recommended!
