Review: Soft, cool, and still looks great after a year - I've been using this duvet cover set for about a year now, and I'm still very happy with it. The fabric is incredibly soft, comfortable to sleep under, and has a nice cooling feel that makes it comfortable year-round. The quality has held up really well over time. After a year of regular use and washing, I haven't had any issues with the fabric, stitching, or button closure. The corner ties also do a good job of keeping the comforter in place. The subtle striped pattern gives the bedding a clean, elegant look that fits well with almost any bedroom decor. If you're looking for a high-quality cotton duvet cover that's soft, breathable, and durable, I highly recommend this one. It has held up beautifully and still feels as good as when I first got it.
Review: Its doesn't get wrinkle after wash - Very nice! I will buy again

## Features

- OUR DUVET COVER SET IS BACKED BY THE GOOD HOUSEKEEPING SEAL: Experience comfort with our 400 thread count 100% cotton sateen oversized king Duvet Cover Set. It protects your duvet from spills and stains for lasting freshness. Experience comfort, convenience, and style with our 3-piece oversized king white cotton duvet cover & sham set. 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 standardised! So you must always measure your comforter before buying its oversized duvet cover king. Our 3 piece oversized king size duvet cover set will fit most, as the duvet cover measures 120" wide x 98" long & 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 durable duvet cover oversized king set is machine washable and dryable at home. The 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 oversized king duvet cover set. 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.

## Questions & Answers

**Q: What material is this duvet cover set made from?**
A: Our duvet cover set is made from 100% pure cotton, which is breathable, soft, and durable. Cotton helps regulate temperature and becomes softer with every wash, providing a comfortable sleeping experience.

**Q: Can I wash these duvet covers in hot water?**
A: Hot water washing is acceptable, but it may slightly shorten the lifespan of any cotton duvet cover. For optimal care, machine wash in warm water. Cotton duvet covers last a few years, while our high thread count options endure 5–10 years.

**Q: Does this duvet cover have closures?**
A: Yes! The duvet cover features a button closure for a clean, seamless look. It also includes 4 corner ties inside to keep the comforter securely in place and prevent it from shifting during use.

**Q: Would you recommend these duvet covers for all seasons, especially for hot sleepers?**
A: Our duvet covers, made from 100% cotton, are perfect for year-round use and especially ideal for hot sleepers. The natural softness and breathability of cotton help regulate body temperature, keeping you cool and comfortable throughout the night.

**Q: What is the return policy if I'm not satisfied with these duvet covers?**
A: Amazon's return window covers these duvet covers - so you can buy them with confidence even if you have washed or used them.

### ⭐⭐⭐⭐⭐ Its doesn't get wrinkle after wash
*by D***E on August 6, 2026*

Very nice! I will buy again

### ⭐⭐⭐⭐⭐ Love the sateen. Not too shiny. Excellent buy
*by V***A on June 25, 2026*

Very cosy! High quality! Very soft. Much more silky than a percale weave but after a wash- i don’t see much difference in the shininess of a sateen weave and a percale weave. Very happy with the sateen. O I do wish it had a middle tie at the top of the duvet cover - would help my Martha Stewart Comforter sit more securely inside it in addition to the 4 corner ties and button closure.
