This is beyond awesome!
Color: Green Bamboo(2300gsm), Size: Queen
I have Airbnb properties and I have bought all sorts of bed toppers. Nothing that I have ever bought has been THIS perfect! Anything with polyester is going to fail you. This one is exactly what I was hoping for which is ONLY shredded memory foam that will last and give you what you want for a cloud like experience!! I just got delivery of this one and unpacked it! It is above and beyond anything I could hope for! It is 100% shredded memory foam through and through, very nice and thick!! It's extremely well made and well packaged. I am totally thrilled with this bed topper! No more experimenting with my purchases anymore.. and sending them back when it's nothing like. I hope. This one is EVERYTHING! YOU HAVE GOT TO GET THIS AND YOU WON'T BE SORRY!

Like sleeping on a cloud!
Color: Green Bamboo(2300gsm), Size: Queen, Color: Green Bamboo(2300gsm), Size: Queen
This mattress topper exceeded my expectations. It's very comfortable, provides excellent support, and helps relieve pressure points while I sleep. The foam conforms well to the body without feeling too soft, and the cover feels cool and pleasant. Since using it, I sleep much better and wake up more comfortable. Excellent quality for the price!

bury me in snuggle sac!!
soo i’ve purchased 6 of the fuzzy blankets, 2 packs of the socks, the cardigan, and now this gem of a cooling blanket! im usually a heavy fluffy blanket person, regardless of season or temperature, but living in florida it’s sometimes a struggle. figured i’d give this one a try since i’m obsessed with snuggle sac. the blanket is very thin, intentionally, and is such a deliciously soft and unique material! the one side is cooling and really cold to the touch! both sides look very rich and high quality. definitely makes a difference so i’m not waking up hot anymore! in order to replicate my heavy blanket habit, i use the snuggle sac ribbed blanket on top of it, and can always remove it in the night. so happy with my purchase! always keeping my eye out for new releases from them.

Cools quite well, about 85% but works well for hot flashes
Being in perimenopause I tend to have hot flashes at the most inopportune times, especially in the middle of winter where I'm sleeping practically naked and everyone in the house is sleeping with hoodies and sweats and extra blankets. I just found out that one side is extremely cooler than the other and the first night I had it I washed it gently dried it in a very light, delicate setting on my dryer. In fact, I didn't let it dry all the way and let it hang up and the first three nights I slept with this blanket. I slept an entire 8 hours instead of the usual three because hot flashes like to do that to you. Wake you up at 2:00 in the morning or 5:00 in the morning when you have to get up for work in an hour. It's very light. It smells great. It's very soft and one side like I said is cooler than the other and you will feel so much better wearing this or sleeping with this rather. I'm
