Feather sofa cushions: what is inside and what they ask of you

You know a feather sofa the moment you sit on it: it gives, gathers you in and keeps the shape. That is exactly the point, and exactly what needs looking after. What feather cushions have inside, how all feather differs from a foam core wrapped in feather, what the label has to say, and where the feather comes from.

All feather or a wrapped core

In an all-feather seat cushion the whole filling is feather, with nothing inside to hold the shape. It is the softest, and the most dependent on care: with nothing to hold it up, it needs plumping often to get its loft back.

The other usual form is a foam core wrapped in feather. Sophie Conran, who makes sofas in Britain, explains that the foam gives the structure and the feather the softness, and suggests it for anyone who wants a comfortable, settled-in seat with less upkeep.

What feather asks of you

Feather flattens with use and lofts again when it gets air. The Cotswold Company’s care guide asks you to take wrapped-core cushions out now and then, plump them and put them back in their covers, and to turn them every couple of weeks. Caravane, another sofa maker, points out that feather needs room to breathe; otherwise it clumps.

Sofas & Stuff adds two things: don’t leave heavy objects on the cushions for long, as they compress the core, and don’t wash its feather cushions. Before cleaning anything, the label on each cushion is what counts.

What the label says

The European standard EN 12934 sets out how a down and feather filling is declared. According to the summary published by Textination, the German textile industry’s portal, the percentage of down and of feather by weight is mandatory; for instance, “70% feather, 30% down”. Colour and origin are optional.

The same source explains two more details. The word “pure” in front of a species, as in “pure duck”, is only allowed if that species reaches 90%. And the material only counts as new if the “other elements” (fibre, broken feathers, residue) stay below 5%. IDFL, a laboratory specialising in down and feather fillings, tests products to that standard.

Where the feather comes from

The Responsible Down Standard, run by Textile Exchange, is an animal-welfare certification for down and feather. It bans plucking live birds, including during moulting, and force-feeding. It audits the whole chain, from the farm to the finished product, and tracks certified material with its own chain-of-custody standard.

If provenance matters to you, ask for the certificate for the filling, not just the fabric.

What to ask before ordering

With these answered, you know what you will be sitting on:

The filling: All feather, a foam core wrapped in feather, or fibre?
The mix: What percentage of down and feather does the label declare?
Provenance: Does the filling carry an animal-welfare certificate?
Care: How often does it need plumping? Can it be washed?
The cover: Does it come off so the cushion can be taken out and plumped?
