I’ve only used this for several nights. Overall I’m pretty happy with it, especially for the price. It is soft to the touch and has a nice, smooth feel. It’s lightweight but still provides enough warmth for mild to cool nights. I don’t like feeling weighed down when I sleep, so the light fill is actually a big plus for me. If you’re someone who sleeps hot, this is a solid choice. The corner tabs are super helpful. I paired it with a duvet cover and haven’t had issues with shifting or bunching. It also fits my bed well, though I could see it being a bit short on the sides if you have a very thick mattress. This is a great budget-friendly option and seems like it will be easy to maintain.

A Great Comforter for Everyday Use

Size: Full/Queen, Style: All-Season

I absolutely love this comforter! I love the fact it’s machine washable, and it held up really well after the first wash. It fluffed back up nicely, stayed soft, and didn’t lose its shape. It’s not too heavy but still cozy enough to keep you comfortable. For the price, the quality exceeded my expectations, and I am very happy with this purchase. I highly recommend 😊

Excellent down alternative insert

Size: Full/Queen, Style: All-Season

I purchased this down alternative for my Airbnb because we can easily wash it. I love that it is fluffy and warm and easy to put into the duvet. Price was great as well!!

Feels luxury, I approve

Size: King, Style: Warm

I have purchased high end comforters/duvet inserts and this one is somehow my favorite. It's so thick and fluffy. I was going to do the double duvet insert method to create an extra lush bed situation, but honestly it's not needed at all with this comforter! It poofs up wonderfully inside my duvet cover (king duvet, king insert) and it's like heaven. It's very cozy yet airy, and it moves well during the night and does not fee too heavy despite its weight. This thing is definitely on the warm end and probably won't be suitable for Florida summers, but depending on how you set the AC at night it could be fine! The comforter is weighty, it feels like quality, and has a soft fabric. I wouldn't use it without a duvet cover, that's more of an aesthetic choice but I like keeping it clean. The white is very white. Honestly, I will be getting another one simply because I'm so impressed. Definitely no need to drop $300+ dollars elsewhere.

ALL SEASON IS TOO WARM!

Size: King, Style: All-Season

I got the King, All Season, to squeeze into a Queen duvet for extra floof and it's sooo cozy. Highly recommend. I redacted 1 star though because although it says All Season, the amount of down in here feels like it's for winter. The first night I used it I woke up dripping in sweat. It's currently March, I live in Los Angeles area, hitting about 75° weather outside rn, but I sleep with AC full blast at night (usually hit about 64 when I wake up). I can't sleep with it, I'll need to buy the "cool" one, and hope that isn't tooo thin. Don't get me wrong, it's a great insert, but holy hell, it's too heckin' warm. I saw someone else mention it and wish I had honed in on their comment. I don't wanna return it as it was used, so I'm stuck with it now. *UPDATE* I am back because I also bought the "Cool" blanket as well after experiencing the heat of the all season and it too is also too hot for me. I've had a duvet before but I guess not filled to the capacity of these blankets. If you're a hot sleeper maybe look elsewhere?
