Very soft I would like to purchase more colors
I am extremely happy with this comforter and would absolutely purchase it again. The quality exceeded my expectations, especially for the price point. The material feels soft and smooth right out of the package, and it fluffed up nicely after a short time.What I love most is how well it regulates temperature. It keeps me warm without feeling heavy or overly hot, making it perfect for year-round use. The stitching is well done, and the box construction helps keep the filling evenly distributed—no bunching or cold spots.It’s also easy to care for. I’ve washed it once so far, and it held up beautifully without losing its shape or softness. The color is rich and true to the photos, adding a clean, cozy look to the bed.Overall, this is a great alternative to traditional down—especially if you’re looking for something hypoallergenic, lightweight, and comfortable.

Great all season comforter for hot sleepers
Great light weight but substantial all season comforter! I am a hot sleeper and I sweat when I sleep. This comforter is just heavy enough to where I feel cozy but breathable enough to where it doesn’t trap heat and make me hot and sweaty! I like that it is fluffy and not thin feeling. I am currently using it in the winter down south where it’s been in the mid 20s at night. It’s kept me warm. I also used it last summer and I didn’t overheat at night. It’s definitely not a luxury comforter, but its held up great. I own two black ones and rotate them in my bed. I have washed and used them for over 6 months now. No issues at all. Because they are light weight they don’t take forever to dry in the dryer. The outside feels like microfiber and I’m sure inside is your typical down alternative stuffing. It’s about comparable to something you would purchase at target. It looks great on my bed. To be honest you’d never know it is, what I would call, a budget friendly comforter. If you are looking for something that’s really luxurious feeling, you may want to look elsewhere. If you want a great all season comforter, at a good price, that holds up well then I would definitely recommend! Although there’s no duvet straps, I assume you could probably put a duvet cover over it if desired. Overall a great Amazon buy for me. Im about to purchase another for my kids rooms if a different color.

Very comfortable & Light for summer
I’ve sleeping great. It’s good quality for the money, looks good with a lot of versatility where you can easily flip it over making it two colors. It’s been pretty durable and I found it’s pretty resistant to water.

Soft and Comfortable All-Season Comforter
This comforter is soft, fluffy, and very comfortable to sleep with. It works well in different seasons and keeps a nice balance of warmth without feeling too heavy. The size fits my queen bed perfectly, and the corner tabs make it easy to use as a duvet insert. It also looks clean and simple on the bed. Overall, a great everyday comforter for the price.

Cozy cozy blanket
Love this comforter, especially for cold winter nights. During the summer, I place it over my bottom sheet for a soft nights sleep. Stay put very well.

Great Purchase
Used this in our ARI. Very soft and comfortable. I probably will purchase a few more for home. Everyone is always looking for a fluffy and soft blanket. Lightweight, but warm.

Good Quality
This is a nice comforter. We sleep great with it. It's well made and perfectly lightweight, making it ideal for summertime or even winter when the heat is up high. While it is lightweight, it's not overly thin. It's maybe half the thickness of a typical comforter. I do wish there were more color options, but I was able to buy a color that matches my sheets and it saved me from having to buy new sheets to match. My sheets are pretty expensive so that was nice.

Looks nice but not very warm
Comforter is soft, looks nice, and holds up well but is not anywhere near as warm as a true down comforter. Warmth is about as much as a standard bed-in-a-bag polyester comforter so if that's all you need, this will work well.
