Great buy
Size: Twin, Color: White
Pros: 1) Has held up well in the washer/dryer 2) lowest price I could find for down alternative comforters without a high return rate 3) My fur kids adore this brand vs similar big box store brands, especially my finicky cats. 4) Very soft Cons: None that I have experienced. I started searching and found Utopia after Target decided to raise the price on their down alternative comforters. This comforter is a light weight style that holds its own on laundry day, and isn't too heavy in our warm climate. It is great for a multi species household. Team Double Trouble loves it on their raised dog bed (amazon brand), Team Murder Mittens love it on their kitty city condos (available here on amazon) to sunbathe or bird watch, and I like it too as a hot sleeper. It really is a perfect all purpose comforter. 10/10 would buy again.

Pleasant surprise, warm and fluffy
Size: Queen, Color: White, Size: Queen, Color: White
For the past couple years my girlfriend and I have gone through a few cheap comforters. We never really gave much thought to them and subsequently they never impressed us. I grew up using a down comforter and have very fond memories of that blanket. The comfort and warmth was something that I hadn't experienced since I had moved out and gotten my own comforter. So this has been in the back of my mind ever since but I wasn't sure if I wanted to dish out that kind of money for a blanket and also deal with the hassle of dry cleaning it. Also by purchasing a down blanket we'd be supporting an industry in which the down feathers from geese are taken from them and that's not something we personally wanted to support. So for all those reason we started looking into down alternative. The first thing that made me question these products was the price, they seem TOO cheap. I was raised with the mantra, "you get what you pay for" and with that in mind I was quite weary when looking at these products. I always make sure to compare many different products and read through the reviews, both good and bad before I buy something. I decided to take a chance on this particular one as it seemed to be the highest rated by customers and I liked what I saw in the images provided by said customer. If anything, the price was low enough that I wasn't too worried if I didn't end up liking it. Now I wasn't actually home when it arrived but my girlfriend confirmed that it was very flat right out of the package, as was expected. By the time I got home 2-3 hours later it appeared to be fully fluffed. The material it is made of is very soft and comfortable on your skin and I was pleasantly surprised with the thickness/fluffyness. It is a fairly light blanket, similar to a down blanket I suppose in that regard. So far I have only slept with it one night but it did a great job of keeping me warm. I live in Wisconsin and the temperatures this week have been ranging from -10 over night to single digits during the day. I had been using 2 blankets prior to getting this one and sometimes I would still wake up in the night feeling cold. But so far with this blanket alone I have stayed warm which again was a pleasant surprise. I do have to say that this doesn't remind me a whole lot of my down blanket and I think that may have to do with the material used in the shell. And you're not going to be 100% able to recreate a down blanket not using down. So if you are looking for something that feels exactly like down and won't be satisfied otherwise, this might not be for you. However, if you are looking for a good quality, warm, fluffy and affordable priced blanket that will give you that "cloud" like feeling, I think you would be really happy with this blanket. Again this is my opinion from using it for one night, I can not comment on the durability or longevity of this blanket, but I am hoping that it holds up over time. **also our cats immediately fell in love with it, it is their new favorite spot to nap.

High quality duvet!
Size: Twin XL, Color: White, Size: Twin XL, Color: White
Extremely comfortable, soft, and thick duvet! It is also very light despite its thickness, and it makes all my comforters look super fluffy. It keeps me warm without making me sweat. It’s easy to wash, high quality, and it has 3 loops on all 4 sides of the comforter. You could also use this duvet by itself if you wanted to since it is so comfortable and looks like a white comforter on its own. Absolutely love this duvet and do recommend! (I will add another photo of the duvet by itself when I take the duvet cover off to wash it)

Super impressed for the price!
Size: Queen, Color: White
I didn’t have super high expectations ordering this, but it ended up being way better than I thought. It’s really soft and has that fluffy look without feeling super heavy. I was worried it would feel cheap or flat, but it actually holds its shape really well. I’ve been using it for a bit now and it still looks good on my bed, not lumpy or uneven. It’s warm enough but not too hot, so I’ve been able to use it comfortably without waking up overheating. I’ve also washed it and it didn’t fall apart or lose its fluff, which was a big thing for me. For the price, it honestly feels like something more expensive. Only thing I’d say is if you like a super thick/heavy comforter, this one is more on the lightweight side, but I personally prefer that. Overall really happy with it and would buy again.
