Frequently asked questions
What does 15 tog mean in a duvet?
Tog measures thermal insulation; higher tog = warmer duvet. 15 tog is the warmest commonly available tog, suitable for very cold bedrooms. An all seasons duvet typically includes two layers that can be used separately (e.g., 4.5 tog for summer, 10.5 for autumn, combined for 15 tog in winter).
Can you use a 15 tog duvet all year round?
Yes, if it's an all seasons design with detachable layers. The 15 tog configuration is only necessary in colder months. For spring/summer, use the lighter layer alone. Some people find 15 tog too warm even in winter, depending on room temperature and personal preference.
What is the best fill for an all seasons duvet?
It depends on your needs. Down fill is soft and warm but not hypoallergenic and expensive. Synthetic fills are hypoallergenic, cheaper, and easier to care for. Hybrid blends offer a balance. Look for certifications like OEKO-TEX for safety.
How do I wash a 15 tog all seasons duvet?
Always check the care label. Most synthetic duvets can be machine washed on a gentle cycle at 40°C, but down duvets often require professional cleaning. Use a large-capacity washer and tumble dry on low heat with dryer balls to redistribute filling.
Are all seasons duvets worth the investment?
Yes, if you want versatility and year-round comfort without storing multiple duvets. They can be more cost-effective than buying separate winter and summer duvets. However, the quality of layers and connection mechanisms varies, so choose a reputable brand.
