Soft warmth for cold nights
Color: Charcoal, Size: King
This bedding set with faux mink fleece and sherpa backing is perfect for cold weather or low-heated rooms. It’s ultra-soft on both sides, and the down-alternative fill keeps warmth in without feeling heavy. The reversible design lets you switch up the look, and the stitching holds up well. Even after several washes, it keeps its texture and shape. No clumping or loss of loft. A practical choice for anyone who wants comfort, warmth, and simple style.

Great bedding at a great price!
Color: Tide Pool Blue, Size: King
I can’t believe how great this is for the price! Super soft, comfy and very warm. Perfect for wintertime. I don’t think I’d use it for other seasons…but it’s great right now.

Warm, soft, cozy… not very fluffy though
Color: Tide Pool Blue, Size: Full/Queen
I LOVE this comforter!! The color is beautiful, it’s super soft, it’s nice and warm, and it has a nice weight to it. I will say it isn’t as fluffy as it seems in the pictures, there doesn’t seem to be any filling between the 2 layers, and if there is, it’s minimal. It’s more like the thickness of a similar double sided throw blanket. It also has the tendency to grab any small debris which clings to it, but this is to be expected with this type of fabric. I would not recommend this comforter for pet owners as it will definitely be covered in hair and whatever else your furbabies may track in! Despite the lack of fluffiness and it constantly holding on to any loose thread or other random debris, I am still very happy with my purchase. Very good comforter for the price and it looks beautiful on the bed!!

I originally got the King set & loved it so much I ordered another in Queen size!
Color: Charcoal, Size: King
I didn't add a picture because the advertised picture is exactly what it looks like (and my beds not made at the moment, lol). It's so soft, comfortable, cosey and warm. It's thicker and fluffier than I expected, but still very lightweight. The price was great for a king size bed with 2 king sized pillow cases! I love it so much I ordered a second set in Queen size, just to have the cases for my smaller queen pillows that go in front of the King pillows and to have the extra blanket as a cozy throw. The only drawback is it does snag easily on rings, fingernails, etc. (also another reason I ordered the second one to lay across the places that I've snagged & a few that were already snagged when I got them). However, it's so cozy that I didn't want to go through the hassle of sending it back and having to wait for a new one! I'm very glad that it was suggested as an add on when I ordered the mattress pad & that I chose to add it on. I'd definitely recommend it to anyone!
