Whether you need a separate duvet for summer and winter depends on your personal preference, climate, and how much warmth you need while sleeping. Here’s a breakdown of the key factors to consider:
1. TOG Rating and Seasonal Comfort
Duvets are rated by TOG (Thermal Overall Grade), which measures warmth.
- Summer Duvets (2.5 – 4.5 TOG): Lightweight and breathable, perfect for warm weather.
- Spring/Autumn Duvets (7 – 10.5 TOG): Medium warmth, ideal for in-between seasons.
- Winter Duvets (12 – 15 TOG): Extra warm and cosy for colder months.
2. All-Season Duvets
If you prefer a single duvet year-round, consider an all-season duvet, which typically comes in two parts (e.g., a 4.5 TOG + 9 TOG). You can use them separately in summer and combine them in winter.
3. Material Matters
- Natural Fillings (Down or Wool): More breathable and adaptable to body temperature.
- Synthetic Fillings: May be warmer but can trap more heat.
Final Thoughts
If you experience extreme temperature changes, having separate duvets for summer and winter is a great idea. However, an all-season duvet is a practical and cost-effective alternative.
