  • Picture is deceiving
    Verified Purchase

    This product does not look like the picture nor is it as described. It does not have baffles boxes, it is one big sleeve for my duvet. It is good quality and fits well however. Disappointed! to say the least, I ordered it for the baffles box looks

    Very nice quality fabric and construction. Lightweight enough so does not add bulk and weight to the comforter.

  • Item not as pictured
    Verified Purchase

    If you are looking for a box pattern like the picture shows, you will be disappointed. When I opened the package, I found a plain, no patter duvet. It is very good quality and has alight sheen to it but it is definitely not the picture shown. Had to return it and start my search over!

    You will need a king size insert. We bought a queen and I have about a foot of space on the horizontal side of the duvet.
