Why You’ll Love It+

A softer way to experience your mattress.

A mattress provides the foundation. The Eiderdown Topper transforms what lies above it.

A generous layer of pure Icelandic eiderdown adds softness, loft, and breathable insulation without creating the heavy, compressed feeling of traditional mattress toppers. Hand-filled to your chosen warmth, it creates a more inviting sleep surface from the moment you lie down.

How It Feels

Softness that gently gives beneath you.

The topper creates a naturally plush layer between the sleeper and mattress, cushioning the surface without sacrificing breathability.

Eiderdown’s exceptionally fine structure allows it to loft around the body while remaining remarkably light. The result is a softer, more comfortable sleep surface that feels indulgent rather than bulky.

How It Looks

Quiet luxury, from the first layer down.

Naturally lofty and beautifully understated, the topper gives the bed a fuller, more inviting appearance without looking overfilled.

It’s soft profile settles naturally across the mattress, creating the refined, effortless look of a thoughtfully made luxury bed.

Warmth & temperature

How warm is it, exactly?

Eiderdown traps still air rather than adding bulk, so it reaches a given warmth at roughly a third the weight of goose down. Match the weight to your bedroom temperature at night, not to the season outside.

If you sleep hot, or share a bed with someone who does, step down one weight.

Choosing your warmth

Three Heights. One softer sleep surface.

Eiderdown responds naturally to the surrounding environment, so the right fill is determined more by your bedroom and sleeping preference than by the calendar.

The heights are measured in inches of the finished topper with pure eiderdown.

Nest to needle

Gathered by hand. Filled by hand. Finished by hand.

The story of an Eiderdown Topper begins long before it reaches the bedroom. After the nesting season, eiderdown is carefully gathered from wild nests without taking it from living birds. It is then cleaned, prepared, tested, and individually weighed before being placed into the finished topper.

01Gathered after nesting - Eiderdown is collected only after the birds and ducklings have left the nests.
02Carefully prepared - The down is cleaned, processed, and tested to preserve its exceptional softness and loft.
03Filled to order - Each topper is filled to its selected gram weight and individually finished in Iceland.

Luxury should not be disposable. A tightly woven, breathable organic cotton shell protects the delicate eiderdown within, while carefully finished seams help maintain the topper's structure through years of use.

01Down-proof organic cotton shell - Designed to contain the fine eiderdown while allowing the material to breathe.
02Carefully finished construction - Precision stitching helps maintain the fill's distribution and shape.
03Made for long-term comfort - Backed by a 10-year warranty and designed to retain its loft with proper care.
What is eiderdown

The rarest down on earth

Eiderdown is not farmed or plucked from birds. It is the soft breast down that female eider ducks use to insulate their nests. Once the nesting season is over and the birds have left, the down can be carefully gathered by hand. Its naturally interlocking structure allows it to trap remarkable amounts of air while using very little material, one of the reasons genuine eiderdown is prized for exceptional warmth, softness, and lightness.

I bought a new king size mattress, and while it felt comfortable I started waking up with back pain. Rather than go through the headache of a return I added this eiderdown topper and what a difference. Pains mostly gone, the mattress stays pretty cool and it's more comfortable than the mattress top layer material. No issues with the topper sliding or moving, it really has been a great experience for me.

Questions before you commit

Please read our FAQs page to find out more.
Is an eiderdown topper worth it?+
For sleepers looking to soften their mattress and add a layer of natural loft, an eiderdown topper offers an exceptionally lightweight and luxurious alternative to conventional padded toppers.
Will it change the feel of my mattress?+
Yes. The topper adds a softer, more cushioned surface while allowing the underlying mattress to remain part of the overall support system.
Does the topper flatten over time?+
Eiderdown naturally compresses under use and regains loft when aired and gently fluffed. Proper care helps maintain its volume and performance.
How should the topper be cleaned?+
Professional dry cleaning by a cleaner experienced with down products is recommended. It should be stored in a breathable bag rather than compressed for long periods.
Can it be washed?+
Dry clean only, with a cleaner experienced in down. In practice most owners never need it, airing outdoors twice a year and regular fluffing keeps the loft.
How long does Eiderdown Topper last?+
With appropriate care, a high-quality eiderdown topper can remain comfortable for many years. The product is backed by a 10-year warranty.
