Sisu is a checked upholstery designed by the celebrated designer Nanna Ditzel, which links to the iconic textile Hallingdal she created for Kvadrat in 1965. It is curated by artist Danh Vo, who discovered the design in the Kvadrat archives and chose it for an exhibition at Denmark’s National Gallery (SMK) entitled ‘Take My Breath Away’.
Danh Vo discovered Sisu as he explored Nanna Ditzel's output – a journey sparked by his curiosity around the relationship between textiles and furniture. As he delved into her acclaimed body of work, he discovered that often she did not put her name to her most famous designs.
The expression of Sisu is reminiscent of looking at Hallingdal through a magnifying glass. The textile is woven with thick, voluminous woollen yarns and features a bold yet subtle, checked pattern. Blocks of colour play across its surface, rising to tactile, rhythmic effect.

Durability {{site.selectedConfiguration.martindale || "70,000 Martindale"}}
EN ISO 12947
The Martindale method is the most widely used method for testing upholsteries for abrasion resistance. During testing the fabric is rubbed against a standard wool textile with a given weight-load applied. Running at intervals of 5.000 circular rubbing motions, the test continues until two threads are worn.
Minimum requirements
Private and low traffic public areas: 10.000 – 15.000 rubs
High traffic private and office spaces: 15.000 – 25.000 rubs
Public spaces and transportation: 25.000 – 45.000 rubsDurability test results exceeding ACT performance guidelines (> 40,000 rubs) are not an indicator of product lifespan. Multiple factors affect durability and appearance retention.

Pilling 3-4 (ISO 1-5)
EN ISO 12945
Pilling is the term used to indicate whether small balls of fibres, known as pills, form on the surface of the fabric due to wear.
It is evaluated on a scale from 5 (best) to 1 (worst).
-
LightFastness {{site.selectedConfiguration.lightFastness}}
ISO 105-B02
Lightfastness relates to the ability of a textile to retain its colour under light. When testing for lightfastness, samples are exposed to artificial daylight for a specified period.
The evaluation scale ranges from 1 (worst) to 8 (best). An increase of one point corresponds to a doubling of the lightfastness, i.e. the same fading takes twice as long.

Flame retardant performance depends on the type of foam used. There are differing requirements concerning the flame-retardancy of textiles dependent on the area of application, country or even region. Our textiles pass the majority of international standards and are also tested for a selection of regional requirements.

Fastness to rubbing {{site.selectedConfiguration.fastnessToRubbing}}
ISO 105-X12
The term for determining the resistance of the textile’s colour to rubbing off and staining other materials. A distinction is made between wet and dry rubbing.
It is evaluated on a scale from 5 (best) to 1 (worst).

Danh (pronounced Ya:n) Vo was born in Vietnam in 1975 and arrived in Denmark at the age of four. Hoping to reach the USA, Vo and his family had fled Vietnam on a boat, when they were picked up by a Maersk vessel in the Pacific Ocean and taken to Denmark.
Danh Vo is a graduate from the Royal Danish Academy of Fine Arts and the Städelschule in Frankfurt. He has received the international art award Hugo Boss Prize and has presented solo shows across the world. Recent examples include the Solomon R. Guggenheim Museum, New York (2018), Museo Nacional Centro de Arte Reina Sofia, Madrid (2015-16); Museum Ludwig, Cologne (2015) and Museo Jumex, Mexico City (2014-15). In 2015 he represented Denmark at the Venice Bienniale.
In May, Observer.com listed Vo as one of the artists who will change the world in 2018.
Regular cleaning is important in order to keep the upholstery textile looking its best and to prolong its life. Dust and dirt wear down the textile and also reduce its fire-retardant properties.

Regular care
Regular cleaning is important in order to keep the upholstery textile looking its best and to prolong its life. Dust and dirt wear down the textile and also reduce its re-retardant properties. Vacuum frequently, ideally every week, at half power where appropriate. Wipe upholstery fabrics made from polyurethane with a dry or moist cloth. May also be vacuum cleaned with a soft brush.

Stain removal
If you act quickly, it is not difficult to remove spills and prevent stains from forming. However, we cannot guarantee complete stain removal. First, scrape off any liquids or hardened residues with a spoon or a scoop before you proceed. Any loose particles must be vacuum cleaned before further cleaning. Liquids must be soaked up with an absorbent napkin or cloth. Remove non-greasy stains by carefully dabbing with a lintfree cloth or sponge wrung out in warm water. Edge marks can be avoided by dabbing gently in circular motions towards the centre of the stain with a clean lint-free cloth. Remove greasy stains by using appropriate detergents or solvents. In all cases, we recommend to test stain-removal agents on an inconspicuous area first, to see if there is any effect on the cover. Make sure to dry the fabric fully before use. It may also be necessary to use a hairdryer to avoid leaving edge marks. This applies especially to microfibre textiles. These tips are purely recommendations and cannot guarantee complete stain removal. In all cases, we recommend contacting a professional dry cleaning. In order to ensure satisfactory results, particularly for large stains, we recommend to contact a professional dry cleaner. It is important to state whether the stain has already undergone treatment.

Professional cleaning
Regular maintenance and cleaning removes dirt before it settles in the fabric and damages the fibres. Appropriate maintenance and regular cleaning can prolong the textile’s life cycle and reduce costs for renovation and repair, replacement and disposal. Extraction cleaning/carbonated cleaning is meant for major deep cleaning to be performed only when necessary. pH neutral carbon dioxide solutions are recommended as soap should not be used. It is important to use a suitable mouthpiece for upholstery fabrics as extraction cleaning is useable for both upholstery and rugs. Make sure to let the fabric dry fully before use. If the textile is glued attention must be paid to the temperature of the cleaning agent, max. 55-60°C is recommended. It is also important to avoid excess use of cleaning fluid, do not saturate the textile. If the fabric is very dirty it might be necessary to repeat cleaning. We do not recommend a steam cleaner as the steam will force dirt deeper into the textile and will move up to the surface later. Due to excess dye in jeans, dark jeans may leave stains on textiles; cleaning may not always lead to satisfying results.

Impregnation
We do not recommend impregnation of woollen upholstery fabrics, as wool itself is dirt-repellent. Impregnation of fabrics made from 100% Trevira CS should be avoided since it decreases the fabric’s permanent flame-retardant attributes.
-
Removable covers
Removable covers made from Trevira CS can be machine washed at maximum 40/60°C. Moreover, it is possible to wash certain cotton fabrics and micro-fibre textiles. Removable covers made from wool cannot be washed but should be dry cleaned. Use washing detergent designated for coloured textiles and obey the dosage. Wash the fabric inside-out and load only half on the machine. Spin-dry the fabric with decreased speed. The covers should be dried while suspended and mounted or applied while still slightly damp in order to ease the process. Not all covers with zippers are designed to be removable. Please ask the furniture manufacturer. We recommend contacting a professional dry cleaner for especially huge covers.
