There are a few factors to consider when choosing the right comforter for yourself or your family, but the most important one is the usual temperature in your bedroom. If your bedroom is not A/C’d then obviously this temperature could fluctuate with the season, so it’s best if you choose the season in which you would like to sleep in the silk comforter first. Unfortunately, there is no industry standard for name-weight-temperature correlation yet, so it could be difficult to tell if a winter comforter is actually for winter as it could be marketed to someone whose winter is a lot milder than your own. There is a general guideline, however: For a bedroom at 68F/20C, a queen size comforter weighing approximately 0.9-1kg/2lb should best suit your needs. With every 3C/6F degree decrease, add 0.3-0.5kg/0.6-0.9lb to the weight of the comforter. So if you are expecting to sleep in a bedroom with a temperature of 14C/57F in the fall/winter season, the comforter should weigh approximately 1.5-2kg/3-4lb. Of course, this is just a rough estimate and only used as a reference.
