Buying a down duvet is no everyday purchase. The duvet stays, often a lifetime. What you check on the label and with the seller:
The filling
The percentage of down. The higher, the lighter and softer the duvet lies. We typically work with ninety per cent down and above.
The origin
Goose or duck down. Both are real down. Goose down is a touch lighter at the same warmth. Duck down is more resilient and generally more affordable.
The European standard
EN12934 classifies fillings by purity. Class I is the highest, new down from mature birds. A good duvet states its class on the label.
The fill power
A number telling how much volume the filling occupies. Above seven hundred we speak of premium down.
The casing
Tight enough to keep clusters in, open enough to breathe. Ask for the thread density.
The size
Standard sizes do not fit every bed. Ask whether tailor-made volants are possible.
The finishing
Channels or cassettes. Both have their place, ask what the house recommends for the way you sleep.
After-sales service
Washing, refilling, mending. With us it belongs to the purchase. Ask with each purchase what happens after five, ten, twenty years.
A good duvet you choose once. The rest of its life follows on the house that makes it.
