Ok
Color: Dark Teal, Size: King
Looks pretty but not on my bed. It constantly looks messy. I don’t like the lack of neatness.

Couple Win
Color: Spa Blue, Size: King
The Amazon Basics Lightweight Soft King Size Comforter has been a wonderful purchase for our home! The comforter is incredibly soft, comes in beautiful colors, and is the perfect lightweight option for year-round use. My husband and I have very different sleep preferences—I tend to run hot while he’s always cold—but this comforter somehow works perfectly for both of us. It’s breathable enough that I stay comfortable while still providing enough warmth for him. We finally started sharing the same blanket again, which is a win in itself! Highly recommend for couples with different temperature preferences. 🛏️💕✨

Light Weight but Not Hot
Color: Dark Grey, Size: King
Ok... I absolutely love this comforter. In fact, I use it on three different beds. The colors are perfect. The material is soft. It's extremely light weight, but it keeps you warm in the winter and does not overheat you in the summer. I have this in King and Queen, and the sizing has been good for both. I have thrown it in my washing machine multiple times, and it holds up well. Great quality, low price.

Navy is pretty, but doesn’t feel like a great quality set.
Color: Navy Blue, Size: King
I purchased the Navy. The color is great and the pleated pattern is a nice touch. My daughter has the white and it’s very soft. The navy is not, though. So that was disappointing. It’s also not breathable. It’s not thick, but just not breathable. I actually get pretty warm at night with this one when I don’t normally with any other blankets. It also seems on the small side. We have a king and always buy king, this just feels a little smaller. Doesn’t feel high quality. I would not buy again.
