Adjectives are unfalsifiable
Luxurious is not a measurement. Fill power is. So is cluster content, and so is the number of grams of down actually inside.
Goose down, made properly
Down chosen for how it feels in year ten, not just in the shop. Light enough to forget you are under it, warm enough to keep, and made to be repaired rather than replaced.
Everything behind it is published, for anyone who wants to look. Not as a selling point. We would simply rather be checked.

What we are for
Walk into any bedding shop and you will find a duvet described as luxurious, cloud-like and hotel quality, at four or five times what the material inside it costs. What you will rarely find is the one thing that actually determines whether it is good.
Luxurious is not a measurement. Fill power is. So is cluster content, and so is the number of grams of down actually inside.
When nobody publishes specifications, nobody can compare. That gap is where a four-times markup lives comfortably and unchallenged.
Every figure we print is on a lab report you can read. If we will not publish a number, we will not sell the product.
What is inside
None of them are secret and none of them are complicated. They are simply not printed, because printing them invites comparison. We print them.
How much space a fixed weight of down expands to fill. Higher means more warmth for less weight, and a product that packs smaller. Our floor is 750, and we target 800 and above.
Measured to EN 12130 or GB/T 14272, in cubic inches per 30g.
The share that is genuine three-dimensional down cluster rather than flat feather. This is the figure that decides how a duvet feels in year five, and it is the one most often left out.
A high fill power with poor cluster content is the oldest trick in the category.
Goose or duck, and what percentage. Goose clusters are larger and hold loft longer. We buy goose, and the report says so in percentages rather than adjectives.
Stated as a percentage on the lab report, not as a word on the packaging.
The actual grams of down in the product. A superb fill power with too little fill is a cold duvet, and no amount of marketing changes that arithmetic.
Printed on every product page and on the label itself.
This is an example of the format, not a product on sale yet.
The range
We start narrow deliberately. Every line has to meet the same published specification before it ships, and we would rather do four things properly than fourteen approximately.

Box-baffle construction so the down cannot migrate into cold spots, in the sizes Israeli beds actually use.
200 × 220 cm to start

The companion to the duvet, at a fill weight chosen for support rather than for looking plump in a photograph.
50 × 70 cm

The line we have sold before, rebuilt around everything that went wrong the first time. Two-way zips, reinforced stitching, a repair kit in the box.
Two-way zip, joinable

Clean, light and genuinely packable, in the everyday shape people actually reach for. No visible branding, no technical clutter, folds into its own pouch. Fit is unforgiving, so two sizes done properly before six done carelessly.
Ultra-light, packable, M and L first
Ethics and traceability
The Responsible Down Standard certifies that down came from birds that were not live-plucked or force-fed, audited along the whole chain. Plenty of sellers print the logo. Far fewer can tell you what it actually covers.
A factory certified for apparel is not certified for bedding. We check the scope certificate covers the exact category we are buying, every time, because a jacket certificate cannot carry a duvet.
It certifies the factory, not your shipment. The document that covers the actual goods is a Transaction Certificate, issued per shipment. We write it into the purchase order before production starts, not after the goods land.
Certificate numbers can be checked against the certifying body's public register. We publish ours so you can.
We hold suppliers to this standard in writing before we place an order. It is the same standard we ask you to hold us to.
Built to last
Our first production run had a written list of faults. It was never acted on. This time the list is the specification.
What failed
What we now specify
Stitching too weak
Reinforced stitching at every stress point
Liner below the promised quality
Shell and lining published on the product page
No two-way zip, so bags could not be joined
Two-way zips, left and right handed
No spare parts, zips especially
A repair kit with a spare zip pull in every box
Only one tier, no range
A clear range, with the difference stated in numbers
A zip is the single most common real-world failure on a down product, and it is the cheapest thing in the whole bill of materials. Shipping a spare costs us almost nothing and tells you exactly how long we expect the product to last.
Our story
Ansera is built by the team behind Lutra, an Israeli company that imported goose down products directly from China. Not through an agent: our own shipment, our own commercial invoice and bill of lading, our own customs clearance.
That line sold out completely. Then COVID closed the routes, and the years that followed in Israel were not years for launching a considered premium brand. The work stopped, and the relationships went quiet.
We are coming back, and narrower than before. One material, done properly. Goose down, bought on published specifications, certified for how the birds were treated, and priced so that the quality is obvious against what the heritage names charge.
The name comes from the Latin for the bird itself, Anser anser. It seemed more honest than inventing a word that sounds expensive.
