    Talk about a BIG comforter!

    This comforter lives up to its advertisements for being 25% bigger than a standard King size comforter. My wife has been obsessively looking for something that will fully cover all sides of our bed, since we have a rather thick mattress (16”) on top of a box spring. This comforter does just that!!

    Very comfortable.

    I highly recommend the Duvet and cover if you are in the market. Very large with plenty of extra cover so no one gets left out in the cold.

    Best (and biggest) in class

    My husband and I have been looking for a duvet that we didn’t have to fight over all night but would keep us cool and covered all summer long and this duvet insert (paired with the duvet cover) is just the ticket. Soft and breathe-able, but plenty enough to avoid a tug-of-war all night!
