Know before you buy
The lightweight option is ideal for warmer climates or hot sleepers, while the mid-weight is a versatile choice for year-round comfort in temperate rooms. Choose the heavyweight option if you live in a colder climate or prefer a substantial, cozy feel during the winter months.
The baffle box construction creates internal walls that allow the down to expand fully, maximizing loft and warmth. It also keeps the fill evenly distributed across the duvet, preventing cold spots and clumping over time.
Yes, the Sferra Cornwall Duvet is RDS (Responsible Down Standard) Certified. This ensures that the down is sourced from animals that have been treated humanely and ethically throughout their lives.
This duvet is machine washable, making it easier to maintain than many other high-end down products. Always use a large-capacity machine and follow the care instructions to ensure the down remains fluffy and properly distributed.
The Cornwall Duvet features corner silks designed to anchor the comforter to the inside of your duvet cover. This helps keep the duvet securely in place and prevents it from bunching up while you sleep.
Cotton batiste is a lightweight, plain-weave fabric known for its exceptional breathability and soft, crisp hand-feel. At 345 thread count, it provides a durable yet airy casing that allows the high-loft down to breathe without letting the fill escape.
