Love it!
Color: Red Buffalo Plaid, Size: Full/Queen
Instantly became my favorite comforter for winter months. Colors are vibrant and beautiful; soft and warm; appears to be durable. I would get another of it came in others colors. Paired with the Amazon Basics red buffalo plaid sheet set. Matches my pajamas and my dogs’ bandannas perfectly!

Comfortable and light
Team Name: Lightweight Comforter, Size: Twin, Color: Green
This comforter is nice and soft. I was looking for something lightweight and not too thick and this has been perfect as I get very hot during the night. Pretty color and low price too!

Was leary of the price but honestly it's a really nice comforter. Not to heavy. Not to thin. Highly recommended this if you want a budget friendly comforter for your bed. Would buy again.
