I was saddened when I learned this wasn’t a duvet cover that I could open because I was scared it wasn’t going to be fluffy enough on its own so I bought a comforter to add inside thinking it was a zipper duvet. however, I was very pleased to find out that I was incorrect in thinking it wasn’t fluffy enough, it’s very soft material, the comforter itself is quite squishy and the shams aren’t the ones with a single opening but with the middle opening (if that makes sense) which I don’t really mind but others may like to know. either way, I am very happy with this purchase as it exceeded my expectations and I could not be less disappointed. 
I’d also like to add that you can ask the seller questions and they very kindly respond with a helpful manner which was also appreciated.
