FAQ
Will this comforter actually regulate my temperature?
Yes. mellow is designed with a dual-layer system: the CoolWick™ layer pulls heat and moisture away to keep you cool, while the HeatLock™ layer traps warmth when you need it. Whether you run hot, cold, or fluctuate, it balances your body temperature for better sleep.
Do I need a duvet cover with this?
Nope. mellow has a built-in duvet-style shell, so you get the clean, styled look without the stuffing, slipping, or shifting. One piece. No extra layers. No hassle.
Can I really put the whole thing in the washing machine?
Yes, the entire thing. mellow is fully machine washable and dryer-safe. You can toss it in as-is, or unzip the layers to fit smaller machines. No covers to remove. No dry cleaner required.
How is mellow different from Buffy, Tuft & Needle, or Rest?
mellow is the only comforter designed as a 2-in-1 sleep system — not just a blanket. It regulates temperature more intelligently, doesn’t require a duvet cover, and is fully washable without losing shape. It's built for how people sleep, not just how beds look in ads.
Why is it priced higher than a normal comforter?
Because it does more. mellow replaces your comforter + duvet cover, adapts to how you sleep, and lasts longer. It’s made with premium, certified materials that stay soft, breathable, and structured, even after dozens of washes.
Is it good for couples who sleep differently?
Yes. Each layer can be used separately or together, so it adapts to different sleep styles and temperatures. One person sleeps hot, one sleeps cold? mellow covers both — literally.
Can I return it if I don’t love it?
Yes, you have a 30-day return period!
Is it good for sensitive skin?
Yes. mellow is made with OEKO-TEX® certified fabrics that are hypoallergenic and safe for sensitive skin. It’s clean, breathable, and antibacterial by design.
Care
Machine-washable. Tumble dry low. Hang to dry recommended.
Simply unzip and detach the comforter into two pieces, machine wash and dry, and enjoy effortless freshness.

Frequently asked questions

Yes. mellow is designed with a dual-layer system: the CoolWick™ layer pulls heat and moisture away to keep you cool, while the HeatLock™ layer traps warmth when you need it. Whether you run hot, cold, or fluctuate, it balances your body temperature for better sleep.

Can I really put the whole thing in the washing machine?
Yes, the entire thing. mellow is fully machine washable and dryer-safe. No dry cleaner required.
We recommend separating the comforter’s two layers before washing; machine-wash each layer in cold water (≤ 30 °C) on a gentle cycle, then tumble-dry them separately on low heat (40–50 °C) for at least two hours or until completely dry.
How does mellow compare to Buffy, Rest, or Tuft & Needle?
Unlike one-layer comforters, Mellow offers two layers you can zip together or separate for temperature control. No cover required. Fully washable. Customizable. It’s everything others aren’t.
Why is it priced higher than a normal comforter?
Because it does more. mellow replaces your comforter + duvet cover, adapts to how you sleep, and lasts longer. It’s made with premium, certified materials that stay soft, breathable, and structured, even after dozens of washes.
Is it good for couples who sleep differently?
Yes. Each layer can be used separately or together, so it adapts to different sleep styles and temperatures. One person sleeps hot, one sleeps cold? mellow covers both, literally.
Can I return it if I don’t love it?
Yes. Every comforter comes with a 30-night risk-free trial. If it’s not the best sleep you’ve had, send it back, no hard feelings.
Is it good for sensitive skin?
Yes. mellow is made with OEKO-TEX® certified fabrics that are hypoallergenic and safe for sensitive skin. It’s clean, breathable, and antibacterial by design.
Does it come with a trial or warranty?
Yes to both. mellow includes a 30-night trial and a lifetime warranty. We’re confident it’ll be the last comforter you’ll ever need.
