Down: Luxurious, lightweight, and breathable. Ideal for all-year comfort.
Feather: Provides firmer support and is suitable for those who prefer a slightly weightier feel.
Goose Down: Offers superior loft, warmth, and luxury.
Duck Down: A more affordable option that balances comfort and support.
Aerelle® Cool Night: Ideal for those who tend to overheat, providing excellent temperature regulation and cooling comfort.
Choose the fill that best suits your personal preferences and needs for the most comfortable and restorative sleep.
What is the best way to wash my bedding?
Always refer to the care label on your product for specific instructions. For general guidance:
Duvets & Pillows: Professional cleaning is preferred, as commercial machines offer the space needed (around 50% empty capacity) for even re-lofting. If washing at home, use a gentle cycle at 40°C and dry thoroughly on low heat.
Mattress Toppers: Spot clean only. These are not suitable for machine washing or dry cleaning.
Regular fluffing, rotating, and airing will help preserve freshness, loft, and performance.
