The Mellow Temperature Controlling Comforter’s innovative design puts an end to the nightly struggle for a comfortable temperature, so you can wake up feeling rested, rejuvenated, and ready to start your day. _“I absolutely love this comforter! It’s the perfect level of comfort! Pillowy soft while it provides warmth and comfort it also keeps me feeling cool.”_ -Suzanne M. **GET YOUR COMFORTER NOW** AS SEEN ON  Temperature Controlling Comforter from Mellow Sleep on Vimeo  Playing in picture-in-picture Play Fullscreen   2 comforters in 1 With Cooling Tech  All Season Comfort Year Round  Award-Winning Softest Comforter of 2025  Rated 5 Stars By 99% of Customers ## Adjust Your Warmth In Seconds! ## CloudControl™ Dual-Layer let's you choose how warm or cool you want to sleep. Slide 1 of 3        **GET YOUR COMFORTER NOW**  ## YOU’LL NEVER GO BACK! Simply Zip or Unzip for a More Cozy or Fresh Feel Most comforters are poorly made “one-size-fits-all” designs with cheap filling that either traps heat or lets it escape completely. Our Temperature Controlling Comforter fixes that by letting you choose between a warm or cool feel... How? If you sleep hot, simply unzip for a more fresh, airy feel. But if you sleep cold, zip it up and enjoy a cozy, warm sleep. **You literally get 2 comforters in 1!** ## GET A FULL NIGHT’S REST ## Regulates Temperature, & Promotes Restful The Mellow Comforter’s Dual-Layer Sleep System™ was created by sleep experts to help your body naturally rest in the ideal temperature zone. This doesn’t just feel good, this proper temperature regulation helps relieve the main problems associated with poor sleep: Stops Night Sweats & Overheating Reduces Fatigue Boosts Energy Prevents Chills Promotes Deep, Restorative REM Sleep   **CoolWick™ Bottom Layer**  **HeatLock™ Top Layer** ## Patented Multi Layer Design ## Perfect For Every Season & Temperature Preference The Mellow Comforter always feels comfortable, no matter the season. The secret is in the Dual-Layer Sleep System™: 1. **The CoolWick™ Layer –** The ultra-breathable fabric actively pulls heat and moisture away from your body. Perfect for hot sleepers or warm summer nights to keep you cool and dry. 2. **The HeatLock™ Layer –** The insulating fill traps your natural body heat, creating a cozy cocoon of warmth. Ideal for cold sleepers or for crisp fall and spring evenings. 3. **Zipped Together –** Combine both layers for maximum warmth and coziness, creating the perfect heavy-duty comforter for the coldest winter nights. Finally get a full night of deep, uninterrupted sleep, no matter the season. ## Promotes restful sleep ## Wake Up With Refreshed & With Energy! Most comforters (even the expensive ones) trap body heat and force your body into a nightly battle for thermal regulation. This prevents deep REM sleep and leaves you feeling exhausted. When you switch to the Mellow Comforter, everything changes overnight! Its CoolWick™ layer breathes and pulls heat away from your body, allowing you to finally relax into the deep, healing sleep it's been craving. Enjoy perfect, uninterrupted sleep, without the night sweats – simply by changing your comforter!   ## LUXURY YOU CAN TRUST ## Certified Materials For A Safe And Comfortable Sleep. Nothing ruins a good night’s sleep like a hot, sweaty comforter… and on the other hand, our bodies absolutely love the feeling of cozy, breathable warmth. That’s why the Mellow Comforter uses our Dual-Layer Sleep System™ that actively adapts to your body’s needs, keeping you at the ideal temperature all night long. Plus, the Mellow Comforter’s OEKO-TEX® Certified cover and Naia™ Sustainable Filling are independently tested and proven safe from over 350 harmful substances. That means it’s 100% safe for long-term skin contact – and it’s perfect for sensitive skin, too!

MarshMellow Comforter  Jamie M.Verified 9/24/2026 I got the head pillow and the body pillow ALSO yes, the puffy blanket. I did not regret! They made the sleeping experience way more elevated.
