Silk obviously comes from silkworms, and silkworms are naturally repellent to these particles. Another great benefit of luxury bedding collections is that they are hypoallergenic. Silk can protect against dust, mites, molds, fungi, and a whole bevy of other things. This can be a great help to those with allergies of these items. Silk bedding is also fire resistant, meaning it is great for everyone just in case, heaven forbid that a fire does occur in your home.
