La Compagnie Dumas also has a duvet and featherbed (over-mattress) workshop where 90,000 and 11,000 pieces respectively are manufactured on an annual basis.

The duvet workshop implements two different manufacturing techniques to meet all of the requests. The first technique, called "soufflée" (blown) permits us to make high-end natural and synthetic duvets. This technique allows us to obtain products with smooth and fluffy fillings.  

The second technique called "nappée" (topped/layered), applicable only to synthetic materials, guarantees a uniform and fluffy distribution of the synthetic fillings.

A sewing workshop is also integrated. It is possible to make the desired sizes in different percales suitable to the filling being shaped.  These covers are then filled using the "soufflée" (blown) technique and then completed.  The distribution of the filling, natural or synthetic, is a major step in the manufacture of these products. Only the expertise and the expert eye of our employees guarantee a uniform and even distribution of the material in the covers before the final stage. Stitching, the last action in the making of the duvet allows for the filling to be attached.  Different types of stitching can be offered, with box stitching being the most prevalent.

To meet ever increasing demand, La Compagnie Dumas has invested in a production line for topped/layered ("nappées") duvets.  This technique is a continuous manufacture of synthetic duvets. The synthetic material is shaped so that it forms a kind of layer and is mechanically distributed before the stitching. The various materials, the layered/topped ("nappé") filling and the fabric, are then assembled together, sewn by a robot/automation process operating with the selected design. All sizes are also possible. The finishes, satin stitch and bias are provided by our staff at the end of the process to offer a wide range of choice.

All the duvets and overmattress manufactured by La Compagnie are conform to the requirements of European Regulation EN 12952 (part 1 and 2) regarding the fire rules (no cigarette fire).
