The duvet's construction features end-to-end sewn-through box stitching, which helps keep the fill evenly distributed and prevents shifting. Additionally, corner loops make it easy to secure a duvet cover, adding to the convenience and longevity of the product. A noteworthy aspect is its hypoallergenic quality, achieved through the FreshLoft process, making it suitable for those with allergies.
