Then again, what could be more luxurious than 100% Mulberry silk as a filling for a duvet? Silk duvets are available in two weights, firstly the 200g summer weight (equivalent to a 4 tog) which is perfect for hot summer nights or for those who prefer to be kept cool. Secondly there is the ‘all seasons’ 400g weight (equivalent to an 8 tog) which is ideal for most people all year round, light enough for summer and warm enough for winter in a centrally heated home. For versatility, the 200g weight silk duvet may be attached together with the 400g 'all seasons' silk duvet, for added warmth in winter. Mulberry silk duvets even come complete with a little inspection zip, discretely stitched into them, simply so the purchaser may inspect the long white silk fibres!

Both types of filling are wonderfully light-weight, appearing to float on your bed. The silk duvet displays all the stiffness of barely whipped cream, whilst the down duvet is more of a fully whipped version. After all, Mulberry silk duvets are created in a different way to down duvets as silk does not require box stitching in order to be kept evenly distributed and eliminate cold spots. This means that silk duvets probably drape that bit better than down duvets. Finally, and by no means least of all, as natural fibres both down and silk have the marvellous ability to breathe, lifting away perspiration so you don't experience the clamminess which often occurs when sleeping under a synthetic duvet.

All in all, it’s still not easy to decide between the two. There is, however, one main benefit of a silk-filled duvet. Silk is naturally hypoallergenic and resistant to dust mites, so a Mulberry silk duvet won't make you sneeze! Could this be the deciding factor between silk and down duvets? Certainly as far as those sensitive to traditional feather and down fillings are concerned, at least. The Mulberry silk duvet has proven to be a hypoallergenic duvet which allows your body to breathe, ultimately providing an extremely comfortable night’s sleep.
