Overview
The perfect sheets don't just feel amazing when you climb into bed, they stay that way all night.
The CloudCool™ Cooling Sheet Set is made from buttery-soft cooling fibers that instantly pull heat away from your body while releasing excess moisture for a cooler, deeper sleep. Silky smooth with just the right amount of stretch, they feel like your favorite loungewear but for your bed.
Unlike traditional sheets that wrinkle, bunch, and pop off the corners, mellow's adaptive stretch design hugs your mattress for a smooth, tailored fit that stays perfectly in place from bedtime to morning. No slipping. No loose corners. No waking up tangled in your sheets.
Thoughtfully designed to help you sleep cooler and more comfortably, every detail (from the breathable fabric to the wrinkle-free finish) was made to turn your bed into your favorite place to be.

We are a mellow family. From the sheets, pillow, mattress pad and comforter. It is so worth every penny!
First off, love love the dark color!! Thank you for more color options. These are soft, sleek, cooling. My only complaint is they are a bit slippery feeling.
Such a beautiful bedding set! I love how soft and lightweight the fabric feels. It’s smooth, comfortable, and gives my bed a clean, elegant look. The cooling material is a lovely feature, and the quality feels great. A wonderful addition to my bedroom!
I really love this bedding set! The fabric feels incredibly soft, smooth, and comfortable against my skin. I especially appreciate the cooling feel, which makes sleeping much more pleasant. The sheets look beautiful on my bed and give my bedroom a fresh, luxurious feel. I’m very happy with the quality and would definitely recommend them!
I love them, they are cool and I love the feel of them. We just upgraded from a queen to a king size bed so I'll definitely be making another order to get a set of these sheets in king size.
These are incredibly soft and fit so well in our bed. We have both noticed that we don’t get quite as hot at night sleeping on these! Definitely our favorite sheet set!
I will only buy mellow products for my bed for now on. The sheet set is incredibly soft and cooling that doesn't make you hot and sweaty like others. Absolutely love Mellow products 😍
These sheets are great! The only negatives were just two things. 1) they took months to get to me and 2) when they did one of the corners of the fitted sheet had two small holes in it, would have sent them back buck thought I would sleep I. Them first just to see if I even wanted them back and YES I wanted to keep them and didn’t even send them back. BUT, I’m just saying if people are expected to pay over $100 for a set of sheets they should not arrive with holes of any kind in them, especially after waiting months to get them. But I DO love them.
I love Mellow products. I have one of everything. The cloud cooling sheets are great for summer. They feel so good and are very comfortable. The silky feel is wonderful on my skin. They keep me cool through the night and it helps me sleep better when it’s hot out. The cooling pillow cases feel so good on my face. They are even nice to use when it’s not hot. I’m using them now and it is fall,. They keep me warm and cozy even when it’s cold outside. There are a lot of pretty colors to choose from. I highly recommend them.
I have shopped and looked for something soft, heavy-ish and not too heavy and sweaty….this is fantastic! The feeling, quality, size, price is just what I was looking for!!
Absolutely my favorite sheets I've ever had. I'm going through night sweats (I'm 51) and this set is amazing. I've been sleeping so much better since using these :)
The sheets are very cool to the touch, just like the cooling comforter. The mellow comforter is super breathable. Nothing makes me over heat at night and I am a hot sleeper.
The only issue I have is the color which I am working with Mellow on currently. I am unsure what shade of white their “white” option is, but everything came in an ivory or cream color and I ordered everything in white. Their customer service has been amazing while trying to confirm everything. Very timely and thoughtful. I would recommend, and already have recommended a friend.
absolutely do not order from this company. the quality of their fabric is poor. the quality of their service is poor. I have been using these sheets for 2 weeks. I have only washed them once, exactly how they said to. in cold water, delicate and tumble dry. it already feels like I have had these sheets for years and like its been thru 100 washes. I want a refund. I also ordered a comforter from here and it never came. after a month I finally got a refund for that. they took 2 weeks to ship out sheets and comforter when their site says 3 to 5 business days. after a month I finally got a refund for the comforter that never came. and im glad it didnt based off the poor quality for these expensive sheets
I feel like these 5 star reviews have to be bots. I had such high hopes for the comforter and the sheets. At first feel, I was like wow what nice material but then getting them on my bed and sleeping with them are a different story. The sheets and the comforter are so slick, trying to make your bed is a nightmare. All the linens are slipping and sliding off, constantly needing to be readjusted. Night time is the same problem. You’re constantly trying to find where the sheets or the comforter went because they just easily slide away. Your pillows slide around. Everything is just slipping and sliding. Good product in theory, horrible in execution.
