Highly recommend this extra soft, plushy, ripple warm fluff blanket! Looks great, feels great!
Color: Light Blue, Size: Twin
Oh wow this is such a nice blanket!! I have 3 of their regular fleece blankets, without the ripple- just plain fleece and they get washed 1x a week for about 2 years now and they have held up beautifully —- except for the mocha one I keep on my bed that my dog loves to dig in is starting to get frayed —- but it is still nicely soft! Just looks a bit worn so popped on for a bed upgrade since we are in winterageddon the saga that never ends this winter 2026…. I was going to order the same mocha again because I really like this brand and I absolutely get the 25$ moneys worth at 2 years… then this rippled one showed up…. Ok let’s try something new. I am SO glad I upgraded to this ripple! It is plush, and soft, and washed beautifully, and dried beautifully in reg cotton heat— even though it says medium heat care…. I put it on my bed and it looks beautiful! The ripples feel so soft and fluffy— but no fluff or fabric cast off! Even going through the dryer I thought for sure I would have a lint tray full—- it really wasn’t a lot! The color of the light baby blue is just perfect for a cream bedroom or as a navy accent color— it’s a cool true baby blue that looks great with my navy beige and cream bedroom. It is so warm! Much thicker feeling than the plain fleece blanket by bed sure—- some will like the heavier weight- I personally like the weight of blankets so this was a win!! 100% worth the price- highly recommend!

Very Soft Blanket NOT Only For Women and Girls Go For it Guys - BUY THE BLANKET
Color: Orange, Size: Queen, Color: Orange, Size: Queen
This bed, sure, gentle, soft queen, blanket for bed, cozy, soft, fall, blankets, for women, cute large fall throws for girls, orange, 90 X 90 inches is sold by: BEDSURE a seller that is located in CHINA The product is made in CHINA The product arrived in a box with a label, stuck on it not like packaging. You would see if you were buying a blanket at a retail store. Upon removing it from its airtight inner sealed bag, it had a very strong chemical odor to it, and it was very smashed. I placed it in the dryer on high heat for 10 minutes and it really did help to remove the odor and fluff the blanket up. I'm a little confused why this blanket is only for a woman and girls? At least that's what I had for when I read the title of the listing so I guess if you are a man, you cannot have this blanket kind of odd and if I were the seller, I would change that because it definitely will affect search results... I used the blanket on top of my bed as an actual comforter. My bed is a full-size bed. I ordered a queen size blanket, and it covers it nicely. It is probably one of the softest blankets I have ever felt in my life and yes, I would recommend this if you were in the purchase for a nice large, soft, cozy blanket!
