When I received my two pillows I was concerned they wouldn't be as fluffy as advertised; they came rolled up and shoved in a small box. However, after some time sitting out they are even fluffier than imagined. Firmness is exactly what I wanted and even after my husband folds them, they bounce back to their previous shape.

Works very well!

It is made of good quality and has definitely helped with my hot flashes at night. Love the color. Soft and light weight. Only thing is it tends to slide off here n there but its no big deal.

The best comforter I've ever had. Like being wrapped in clouds.

I've been suffering for a long time with night sweats due to menopause and have been experiencing insomnia. Even in winter, I sleep with a fan on. I would wake up several times during the night, alternating between feeling cold from being uncovered and hot from being under the duvet. Well, after much research on Amazon, I decided on this product, and it was the best decision I've ever made. I have no words to describe the comfort, the softness of the fabric, and how cool it keeps me. It's thin, but it's cozy and doesn't slip on the bed. Tonight I wasn't fighting a battle in my bed.It really is exactly as described in the product description. I slept without feeling hot and didn't even turn on the fan (my house's heating system wasn't on). I highly recommend it, especially for women going through menopause. It's worth every penny. I think I'll even buy another one in a different color...
