What material is this duvet cover set made from?

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.

Can I wash these duvet covers in hot water?

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.

Does this duvet cover have closures?

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.

Would you recommend these duvet covers for all seasons, especially for hot sleepers?

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.

What is the return policy if I’m not satisfied with these duvet covers?

Amazon’s return window covers these duvet covers – so you can buy them with confidence even if you have washed or used them.
