Frequently asked questions
What is a 90×98 duvet cover?
A 90×98 duvet cover is sized for queen or full-queen comforters, measuring 90 inches wide by 98 inches long. It fits most standard queen-size duvets and provides a snug cover that protects the insert.
How do I choose the best duvet cover material?
Cotton is breathable and durable, microfiber is budget-friendly and wrinkle-resistant, while TENCEL offers eco-friendly luxury. Consider your sleep temperature, budget, and care preferences when selecting.
Are OEKO-TEX certified duvet covers better?
OEKO-TEX certification ensures the cover is tested for harmful substances, making it safer for sensitive skin. It's a mark of quality and environmental responsibility.
How do I keep my duvet cover from slipping?
Look for covers with corner ties or a hidden zipper that securely hold the insert in place. Some also feature button closures that help prevent shifting.
Can I use a 90×98 cover on a different size comforter?
It's best to match the cover to your comforter size. Using a 90×98 cover on a smaller duvet will leave excess fabric, while a larger comforter may not fit properly.
