Review: I purchased this silk quilt for my guest room, and it made an immediate difference in how the space feels. The Misty Blue color is soft and calming, and it gives the room a more polished, pulled-together look than I expected. The filling is 100% Tussah silk, which makes the quilt very breathable and comfortable. It feels lightweight but not flimsy, and it regulates temperature well, keeping you cool without feeling cold. It’s been especially nice for warmer weather and for sleeping with air conditioning. The long-staple cotton shell feels smooth and high quality against the skin. I also appreciate that the quilt is hypoallergenic, which makes it a good option for guests with sensitivities. The corner loops are a thoughtful detail if you plan to use it inside a duvet cover. Another plus is that it’s machine washable, which makes it easy to care for and practical for regular use. The quilt is lightweight, breathable, and comfortable, and it looks more upscale than I anticipated. I’m very happy with this purchase.
Review: I recently purchased new blanket called "Cotton & Silk Luxury Silk-Filling Duvet Insert/Comforter/Blanket," and it really changed how I sleep.

I usually get hot at night, but with this blanket, I don't move around as much because I'm not too hot. It really does what it says and lets me sleep comfortably without waking up. Hugs Your Body: ⭐⭐⭐⭐⭐ When it says it "naturally body-hugs," it's not just fancy talk. This blanket somehow fits to your body. It feels like a warm hug, especially after a long, tough day. To sum it up, the "Cotton & Silk Luxury Silk-Filling Duvet Insert/Comforter/Blanket" is better than I expected. It's an amazing blanket that works all year round. It's fancy, lets air through, and feels like a hug. If you want better sleep, get this blanket. I'm really happy with it, and I think others will be too. Sleep has never been this nice and relaxing.

*by S***G on 9 January 2026*

I bought this silk quilt for my daughter because her dorm gets extremely warm in winter—the central heating works a little too well. This turned out to be the perfect blanket for her. It’s lightweight and breathable, so it doesn’t trap excess heat, yet still feels comfortable. The quality is excellent: a soft cotton shell, silk filling, and very neat, durable stitching. I highly recommend it for hot sleepers or warm bedrooms. Just note that the brand offers multiple thickness options, so be sure to choose the one that best matches your preferred sleeping temperature.
