"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."

I am a hot sleeper and this is without a doubt one of the best things I have ever found to sleep with! I cannot recommend this enough for anyone who sleeps hot/during the summer months. Easily one of the softest blankets I own as well.

Absolutely love this comforter!!
Very cooling, very light, very silky smooth I love the one side that is very silky and cold feeling. Have done more than a couple washes, no balls on fabric very good comforter best one I’ve ever owned. -
★★★★★
Best blanket ever!!!! Rivals my Rest blanket which is twice the price!!! Love the two sides so I can have the cool side for my perimenopausal hot flashes and the soft comfy side for if I’m actually chilly.
