The YnM Weighted Blanket is made from bamboo viscose, meaning it does have breathability and some soothing properties. The only downside is that you’d only be dealing through Amazon (so there’s a possibility of it not being genuine).
That said, it’s not a terrible blanket. You have the option to buy the bamboo cover, so the blanket does come with loops on the corners so that you can anchor the cover to it.
Plus, with it being sold on Amazon, the features and instructions aren’t that clear. The site says you can machine wash the blanket, but it’s best to buy the cover and wash the cover only.
