I'm in a small motorhome and this has helped my sleep quality a ton. I got rid of my big mattress because the 2 camp mattresses I have are smaller in size, but a bit dense than the mattress I had. Uncomfortable for anyone that sleeps on them for long periods and when I come from biking or hiking the pain was making it hard to sleep. These have improved my sleep quality immensely. It also, to my surprise fit well, the cushions are only a few inches. These are up to 18, but the edge is nearly a perfect fit at the start. The straps keep it from moving. The length and width using 2 of the bed rolls is nearly perfect. On mattress the deeper part of the pocket, would fit perfectly. The quality feels great, lightweight and washable, this is one of those items I wouldn't have likely ordered, but trying it is near priceless for my usage. Couldn't imagine how good it must be on a bed.

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...

Yeesss...

Such a lovely soft lavender! Cooling and soft and wonderful. I sleep hot and have night sweats (post menopause is a witch!), but this little comforter kept me cool and dry. I did notice that it wasn't effective with a top sheet underneath it. You really need it to be directly on the skin for the cooling effect. Besides this (and the price) I have no regrets. Will definitely buy again, if it goes on sale.
