Absolutely perfect!
I’ve been on the hunt for a nice down duvet insert for a long time. Previously I had one from real simple and it was just so flimsy that I questioned what it was actually filled with. During my search I looked for fully sewn boxes and a very lofty look. My husband and I use the duvet cover and insert year round so not only did we want something fluffy, but we also needed it to be comfortable. I chose the medium option, the all year one in king size and it’s so beautiful! The perfect weight and fluff inside. We’re warm at night without being sweaty. (Full disclosure we sleep with the air conditioner down low - we like a chill in the air while being bundled). This duvet insert isn’t light on the wallet, but it’s worth every penny spent. I know from the quality of the construction alone that it’ll last a very long time and the down won’t be sloppily shifting all over. I’m very pleased.
