Details
The Klinun duck down topper adds an exceptional layer of cloud-like comfort to any mattress, giving it a noticeably fuller, more plush appearance and making every night's sleep feel like sleeping on air.
Its core uses a dual-chamber construction. The upper chamber is filled with 90% duck down clusters and 10% small feathers — only authentic whole-cluster down is used, not loose fibres, which are far inferior in quality — delivering outstanding softness and a full, enveloping feel throughout the night. The lower chamber is filled with 100% small feathers, which add a subtle layer of firmness and help keep the topper securely in position during sleep.
The outer fabric is 100% percale cotton — a naturally hypoallergenic material of exceptional softness, making this topper ideal for those with sensitive skin or temperature sensitivity who want extra comfort without needing to change their mattress. Four wide elastic straps — one at each corner — allow a perfect fit on mattresses of any depth without displacement during the night. Free delivery. Made in Spain.

Product technical info
Advantages
Cover in 100% DownProof cotton fabric
The cotton subjected to this treatment is completely natural and hypoallergenic. In addition, it maintains optimal body thermoregulation and prevents the finest and softest feathers from escaping through the fabric.
100% adaptable
Down adapts naturally to the shape of each body, helping to maintain a constant level of comfort throughout the night.
Maximum breathability
The natural structure of the down allows free circulation of air inside the pillow, preventing excess sweating and promoting an optimal temperature for rest.
Made with authentic down
Small feathers that cover the inside of the neck of aquatic birds (never terrestrial) and insulate from the cold outside, helping to maintain body heat without causing a feeling of overwhelm. Its natural structure allows rapid recovery after deformation and facilitates free air circulation.
Fill Power 700
Fill Power is an indicator of down quality that measures its recovery capacity after deformations. Klinum specifies this in all its products. The maximum Fill Power on the market is 900, and this product has a Fill Power of 700.
Quality guarantee
Klinum maintains complete traceability of all the down used in its sleep articles. Both the down and the feathers have been exhaustively monitored since the ducks were raised, thus guaranteeing the origin and maximum quality of the fillings.
Manufactured by down clusters
The down cluster is the structure that guarantees the Fill Power of the articles that incorporate this type of filling. Many products that indicate on their labeling that they are made of down do not incorporate clusters, but rather loose fibers, which has a negative impact on the quality and performance of the product.

Full comfort. It's like those American mattresses with a very tasty topper. Let's say that with this topper I managed to make my mattress look like those mattresses that have a built-in topper.
Maria19-05-2026
Perfect fit to the mattress. It fits the mattress perfectly and the comfort is maximum.
Natalia19-05-2026
Breathable. I've had the topper for 5 months and it's wonderful. It's not hot and I have the firmness I was looking for since my mattress is very hard, it was destroying my shoulders.
Ignacio19-05-2026
A real cloud. It has a very good cloud effect. I thought that with the rubber bands it wouldn't fit well but quite the opposite. It fits perfectly to the mattress and does not move. We recommend it.
Francisco19-05-2026
like a cloud. It is wonderful, it has excellent comfort. Both my wife and I are truly surprised. We are people who are very cold in winter and with this feather topper sleeping is amazing. It's a shame not to find him sooner.
Merche19-05-2026
Breathable. We were afraid of purchasing it because of the heat it could give. I consulted the express mattress advisors and they told me that it had very good breathability. Indeed the temperature is not excessive, it is not hot and the temperature is perfect.
Lorena19-05-2026
Very nice. I found this topper because of your comments. We bought a fairly firm mattress and we wanted to lower the firmness or at least have a soft feeling... completely right.
Charo19-05-2026
without exaggeration, the best. It's incredible. Fluffy and very comfortable
