About This
- OUR DUVET COVER SET IS BACKED BY THE GOOD HOUSEKEEPING SEAL: Experience comfort with our 400 thread count 100% cotton sateen grey Duvet Cover King Set. It protects your duvet from spills and stains for lasting freshness. Experience comfort, convenience, and style with our 3-piece cotton duvet cover king size and sham set. Independently tested to earn the prestigious Good Housekeeping Seal. Our product also won the GH Best Bedding award in 2025.
- WHAT'S IN A SET & WILL IT FIT? The sizes for comforters or duvet inserts are not standardized! So you must always measure your comforter before buying its king size comforter cover. Our 3 Piece king size duvet cover set will fit most, as the duvet cover measures 106" wide x 90" long. And the 2 pillow shams in the set measure 21" x 37", to fit king size pillows. Our sheet sets and pillowcases are made from the same 400 thread count fabric for a coordinated look (each sold separately).
- EASY TO WASH & USE: Safeguard your duvet insert or comforter without washing it entirely. Our king duvet cover set is machine washable and dryable at home. This 100% cotton duvet cover features button openings and internal ties for added convenience. Every item bearing the OEKO-TEX STANDARD 100 label is certified as having passed safety tests for harmful substances.
- THE LOOK: Imagine your bed looking beautifully styled with our duvet cover set king size. Our cotton sateen fabric has a beautiful sheen and has minimal wrinkles giving it a crisp and elegant look. Complete the set with matching bed sheets available in the same fabric and color.
- OUR COMMITMENT: We prioritize comfort, community, and sustainability. Since 2022, we've donated over 36,000 bedding items to US charities and removed plastic from our packaging. Sheets are crafted in our family‑owned factory in India with care and quality‑checked—thread count may vary by ±5% due to standard manufacturing limits. Thoughtfully crafted for everyday comfort.

Tired of Waking Up Hot and Uncomfortable?
Most people don’t realize that poor-quality bedding traps heat and blocks airflow, leading to restless nights and constant discomfort.
Synthetic fabrics, low breathability, and heavy materials can make your bed feel warm, sticky, and irritating — especially during warmer nights.
If you’re constantly searching for “cooling bedding” or “best sheets for hot sleepers,” you’re not alone.
