Duvets are built by sewing and feathers between the top and bottom covers, usually cotton. Silk or polyester covers are also used, although less frequently. Down comforters were originally called down comforters, a French word meaning a simple open fabric bag filled with feathers and down. Today, the top and bottom covers, stitched (quilted) together, are held down even in small compartments called partitions or boxes.
There are two basic types of lower blanket designs: a septum and a boxed stitch (also called a stitched). The comforter with a septum has thin strips of material sewn between the top and bottom covers in a checkered pattern. Partitions typically range from 6 to 15 inches, with the same number down in each. The suit of the rack box is also sewn in a checkered pattern; but instead of using small strips of material to separate the top and bottom covers, the top and bottom covers are stitched together, forming boxes. Boxes serve the same purpose as partitions: they hold down, even scattered around the blanket.
What is better design with a partition or box? A box stitch is more common and more expensive to build, so there is a general misunderstanding that the partition is a better design. In addition, many retailers make inaccurate claims about their products, which add to the confusion that most customers have when binding to make a decision about the bottom blanket. The truth is that both types of construction serve the purpose, and both are the best choice for some types of comforters.
Myth : Only the deflector box design “locks” in place.
true : Both partitions and the box-like construction of the line are fixed in separate compartments, which ensure an even distribution over the entire area of the blanket.
Myth : The box stitch design allows you to skip the cold at the points where the top and bottom covers are stitched together, causing “cold spots”.
true : It would be true if the comforter were stretched through the top of your bed, but it is not. In practice, the boxes shrink and fit your body shape, providing the same amount of insulation down as the partition design.
Myth : The partition design makes the blanket more complete than the stitch design.
true : The partition design actually does the opposite; this makes the top blanket flatter. A comforter with short stitches gives a more fashioned and plump look because each square is folded around the edges.
Box Stitch is generally the best choice for lighter weight blankets used in warmer climates and seasons. But box seam is also better suited for heavier blankets (using more filling) when you want a fashioned or puffy look. A septum is usually the best choice for heavier blankets used in colder climates and seasons. Partitions allow full expansion in heavier blankets, maximizing the insulating value of the comforter.
If you want to buy a new duvet and wonder what type of design you should get, first remember that both are excellent and serve the basic function of keeping the displacement down or grouping in the corners. A box stitch is probably the best choice for comforters below 30-40 ounces down (depending on size), and the dividing plate is most likely the smart choice for heavier and warmer down blankets above 30-40 ounces. The main exception is if you are really looking for a sculpted or puffy look, and your main concern is the appearance of the comforter. Then get a short stitch blanket with over 40 ounces of filling.
