A warm hug from this fantastic blanket!
Color: Cream, Size: Throw(50" X 60")
This is my go to blanket when I want to cozy up on the couch. So soft and warm, it’s like snuggling a hug! Washes well and lasts forever years. I replaced mine after 4 years with the same thing in a different color option! Perfect size to cover up and also a nice accent piece on the back of the couch.

In Awe
Color: Tie-dye Taupe, Size: Throw(50" X 60")
this is one of my favorite blankets I’ve ever ordered from Amazon! We use it on our couch. The colors are absolutely beautiful and stunning. It looks very earthy and kind of grounds my living room decor. It is very soft and cozy as well so it serves as many functions in my room! Probably will order another one soon for the other chair. The quality is superb.

The best ever made by anyone is the super, soft, faux fur throw/blanket by BEDSURE!
Color: Black, Size: Twin(60" X 80")
I received my Bedsure super soft Faux Fur twin blanket on 2/3/26. I ordered the black in the twin, 60” x 80” because I love to wrap a throw around me & a regular throw is just not large enough to keep me comfortable. Bedsure bedding or relaxing throws is never a bad choice. I’ve purchased numerous bedding collections & was amazed at the quality of their collections & I will NEVER buy anything BUT BEDSURE bedding. This Bedsure super soft Faux Fur, double sided twin size blanket is absolutely gorgeous & beyond my expectations even though the brand is BEDSURE. The item came nicely packaged & with instructions to just put in the dryer on low to fluff up the blanket which I did & it came out so super soft & elegant. This awesome faux fur blanket is the softest that I’ve ever had. I’m so glad that I read the reviews to help me decide what size to order & the twin size is perfect for me. You can never go wrong with BEDSURE bedding or throws. The Black Faux Fur twin blanket looks elegant on the back of the couch or chair. If I could give this product 10 stars I would. This item was an amazing value for the money. There was no smell to the blanket at all & the quality is fantastic; I’ve never had anything so super soft & is machine washable & can be dried in the dryer. The gorgeous fabric & depth in color is so rich & awesome.

Color: Cream, Size: Throw(50" X 60")
I’m a big fan of Bedsure products—I own and enjoy several. But this one’s my favorite: thick, soft, fluffy, just right. High quality fabric, carefully sewn, washes and dries like a dream.
