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.

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.
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.


A topper made with the same care as the mattress beneath it.
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.
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.
