This is a question which we get asked a lot by customers when they are deciding to buy their goose down duvets. Besides looking at other features such as the percentage of goose down filling, the construction of the duvet plays a vital role in the performance of your goose down duvet as it can affect the efficiency of the insulation.

Whilst both baffle box construction and the sewn through construction duvets would have boxes to ensure the filling is evenly spread out and stays in place, the baffle box construction would have a thin strip/layer of material stitched between the top and bottom of the duvet. This guarantees that there are no cold spots at all throughout the whole duvet for higher tog duvets. On the other hand, with duvets that have a sewn through construction, there will be no goose down filling between the stitching as the top and bottom of the duvet have been stitched through directly. On higher tog duvets, this will cause cold spots between the areas of the duvet where the stitching of each box goes through.

The sewn through construction is always suited for lower tog duvets and this is why many manufacturers will use the sewn through construction for the 4.5 tog duvets, while using the baffle box construction for the 10.5 tog and 13.5 tog duvets. 

Besides the construction of your goose down duvet, there are many other factors which you should also consider such as the fill power, the percentage of down inside the duvet, the thread count of the fabric used and which country the goose down was sourced from. For example, Hungarian goose down has the highest reputation due to its special properties so it’s no surprise as to why our customers love our Hungarian goose down duvets so much!
