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. ## Frequently Bought Together - California Design Den 3-Pc 100% Cotton Duvet Cover Set Oversized King, 400 Thread Count Cool Bedding Set, Premium Smooth Sateen Weave, Button Closure and Corner Ties (White, Oversized King) - California Design Den 100% Cotton Bed Sheets King Size Set - 400 Thread Count Sateen, Deep Pocket King Sheet Set, King Sheets, Cooling King Size Sheets Set, Softer Than Egyptian Cotton Sheets (White) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/218712050-california-design-den-luxury-duvet-cover-set-oversized-king-white](https://www.desertcart.jp/products/218712050-california-design-den-luxury-duvet-cover-set-oversized-king-white) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-09-17*
