Frequently asked questions
What size is a 230 x 220 duvet?
A 230 x 220 cm duvet corresponds to a super king or California king size bed. It is designed for larger mattresses, typically offering generous overhang on each side.
What fill type is best for a duvet?
Down is warm and lightweight but may be expensive and require special care. Down alternative is hypoallergenic, machine-washable, and more affordable. The best choice depends on your climate, budget, and ethical preferences.
How do I choose the right warmth level?
Consider your room temperature and personal sleeping temperature. A lightweight duvet (summer weight) is for warm climates, while an all-season or heavy weight is for colder climates. Some brands offer a 4-season duvet with detachable layers.
Are duvet certifications important?
Yes, certifications like OEKO-TEX (no harmful chemicals), Downpass (ethical down sourcing), and CertiPUR-US (for foam) ensure quality and safety. Look for these on the product page or packaging.
How often should I wash my duvet?
Most duvets should be washed every 1-2 months, but always check the care label. Many down alternatives are machine-washable, while down often requires professional dry cleaning. Using a duvet cover can reduce washing frequency.
