Mulberry West comforters are a comfortable and luxurious, silk-filled comforter in a natural cotton shell. Lightweight but well constructed, these silk comforters feel the way bedding was meant to - comfortable, warm, and soft. You'll not only sleep better because of how they feel but also in knowing that silk is naturally repellant to bed bugs and dust mites. There are three sizes available, and each comes in a handy carry case. Each silk comforter is crafted of 100% certified Grade A Mulberry Silk. With 150 grams of silk filling, each is warm without being heavy and features an unbleached, 300 thread count cotton shell. The silk filling won't shift, and each Mulberry West comforter is tested and certified to contain no lead, bleach, ammonia, PVC, or formaldehyde. Mulberry West even sews in a small zipper so you can see, and feel, for yourself the difference certified silk filling makes!
