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.

I’m really impressed with this duvet insert. It hits that perfect balance of being warm and cozy without getting too hot, something I’m always cautious about with synthetic fills. This one stays comfortable all night. Installation was simple. The duvet has four corner ties, and they line up perfectly with my cover, so getting it in place took almost no effort. It stays put and doesn’t bunch up, which is a huge plus. I chose the pink option because it was the most budget-friendly, and honestly, I’m glad I did. You can’t see the color once it’s inside the cover, but even on its own the pink is soft and pretty if that matters to you. The insert itself is very soft, fluffy, and feels surprisingly luxurious for the price. It seems well-made and durable, and I’ve been sleeping so comfortably with it that I notice the difference right away. Overall, I’m extremely happy with this purchase. If you’re looking for a lightweight, comfy duvet insert that doesn’t overheat, this is a great choice. Highly recommend.

This product is great quality, soft, and fits well inside duvet covers. If your preference is for a thick and slightly more weighted insert, you may find this item slightly too lightweight, particularly in the winter. However, the lightweight nature of this insert makes it very comfortable and easy to put into the cover. The corner tabs are also very easy to secure to whatever cover you choose to pair this insert with.

Love the marshmallowy and cool feel for this duvet inserts. Great quality for the price! Heavy and warm but not too warm or too heavy. Order this when we had a queen bed and just ordered the king when we upgraded to a king mattress.

This comforter is incredibly soft and well made. The all-season thickness is perfect, not too heavy, not too light and it fits the bed exactly as intended with great coverage. The quality exceeded my expectations, and it feels cozy without overheating. Very happy with this purchase!

I’m a bit disappointed, but was on a time crunch and had to take a chance with ordering this one. I tossed it on top of the guest bed, and no matter what way I turned it, it was too small. I ordered a King. After measuring the duvet insert, it measured several inches short on each side. The tag doesn’t say the size or dimensions, but I think I might have been sent a queen. It’s thin, but also expected. It’ll be good for a summer duvet, but again, time crunch. It went through the initial wash without falling apart, so I’m sure it’ll hold up for awhile. Basic, white duvet insert.
