    The only duvet I will ever need

    Even though description says both, duvet and comforter, I am using it as duvet only. I have no need/use for a white comforter but, more importantly, I wanted duvet cover to protect it as much as I can so it lasts me as long as possible because it is so good that I do not want to risk anything. This is, hands down, the best duvet (comforter) I ever owned. Not because of the price tag but because of the quality and comfort. It is light, soft and fluffy at the same time and all that while providing a perfect balance of heat and cool. I have been using it for the past 5-6 month, through cold and warmer weather and I had no issues with cold or heat. The only remark, which is not a big deal, is that I would prefer few more loops for better fit in the duvet cover but, again, this is not a must just personal preference.

    Excellent with or without a cover

    This is a gorgeous piece of bedding. It can be a comforter or duvet insert. The material is so soft and luxurious that you almost hate to put a duvet cover on it, but having that option makes it versatile. It arrives with care, packaged well, and stored in a bag for future use if you need to store it again or like to switch out your duvet insert seasonally. I love the quilting, or as they call it, the baffle box design, that ensures that the down alternative filling stays in place and evenly distributed even with prolonged use and washing without becoming bunched up and lumpy in spots. The corners have ties to attach to your duvet cover if you choose to use one. The fluff and weight of this blanket are extremely comfortable but not bulky. I'm impressed with this brand and the craftsmanship of this product.

    Great down comforter for winter

    This is a great winter down comforter for my guest bed. It is a decent weight and will keep you warm during the cooler nights. I will say if you get warm while you sleep you don't want to use it during the warmer months. I love that it has the corner loops to help it stay secure inside of a duvet cover.

    Super soft and comfortable!

    The corner loops are very solid and make connecting the cover a breeze. This comforter is so soft and fluffy. I opted for a King size for my queen size bed for a slightly oversized fit. Truly luxurious!

    Where has this been all my life?

    This comforter can be used as a duvet stuffing or on it's own and I have used it on it's own with a quilt on top. I love this so much. It made my bed so comfy and cozy over the winter that I am wanting to get more for every room. On it's own it makes my bed look elegant and pretty much like an air bnb or hotel with a bed calling me after a day of travel. I am so impressed with the quality. I have had no shedding through the cloth and it feels so much like down, light and airy. As it has been turning to spring and the nights get a bit colder this is a nice light weight blanket that does not make me sweat. It is perfect for year-round snuggling and cozy comfort.

    A considered pairing

    Finish the bed, thoughtfully.

    Start with what is missing: a cover that fits, the right pillow feel, or an extra layer. Nothing is preselected.
