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

★★★★★

"I ordered from three different brands that all claimed to have the ‘best’ cooling comforter. The moment I unboxed them, Mellow stood out right away. The quality was obvious. After just a few nights of sleep, there was no question in my mind. This one’s the winner."
