“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.”

Perfect for Hot Sleepers

Love my new comforter! The sand color is a nice shade of nude. It is cool to the touch which helps because my husband and I are hot sleepers. We love that it’s not too thick, but it pairs well with having a fan or AC running at night. The only con I would say is that it is not really oversize. We have a king size bed and the comforter hangs over just a few inches on each side, instead of a longer oversize fit. Other than that we are satisfied with our purchase!

Cool Against My Skin

This is the softest most comfortable cover I’ve ever had, and I own many. I LOVE how cool it feels against my skin, and when I awaken during the night I put my hands and arms on it and it instantly is so cooling and relaxing. It’s unbelievable! I don’t know how they made it to do that, but it definitely works wonderfully! I look forward to going to bed every night and cuddling up with this amazing comforter! 💕
