A 240 × 240 cm duvet cover fits a large square duvet of exactly that size. At Zizzz it comes in fine percale and smooth satin, both in certified organic cotton – so you can put together a complete 240x240 bedding set with matching fitted sheets and pillowcases.
For a 240 × 240 cm duvet, choose a 240 × 240 cm duvet cover. The size refers to the duvet and the cover – not to the mattress.
Who is the 240 × 240 cm size for?
240 × 240 cm is a large double duvet for beds 160 to 180 cm wide. It hangs down generously on each side, so both sleepers stay covered, even when one of them turns over in the night. For a 200 cm bed, or if you like even more length, there is 240 × 260 cm.

Still not sure? Take our short quiz: a few questions and you will know which fabric suits you. More about each fabric: our percale duvet covers and our satin duvet covers.
Percale duvet cover 240 × 240 cm
Percale is a tight plain weave: each thread passes alternately over and under the crossing thread. At 220 threads per square inch it gives a fine, matt, breathable fabric that gets softer with every wash. All our 240 × 240 cm percale duvet covers close with a zip and the two-tone models are reversible: turn the cover over and the bed has a new look.
Satin duvet cover 240 × 240 cm
Satin is woven so that most of the threads lie on the surface: the fabric is smooth and soft, with a subtle sheen. At 276 threads per square inch it is denser than our percale and feels more enveloping. Our écru satin in 240 × 240 closes with a zip.
Écru: our satin is undyed
Our écru satin is not dyed. Its warm, natural tone is the original colour of the cotton: no dye is added after weaving.
GOTS-certified organic cotton
Our percale duvet covers are made from GOTS-certified organic cotton. The Global Organic Textile Standard combines certified organic fibres with strict environmental and social criteria for textile processing, and checks the whole supply chain up to the finished product. Our satin is made from certified organic cotton.
Care: washing, drying, ironing
Percale and satin can both be washed at up to 60 °C. Close the zip before washing. Ironing is usually unnecessary: shake the cover out well and hang it up, or put it straight back on the duvet when it comes out of the dryer.
Sewn in Portugal
Our duvet covers are sewn in Portugal, in percale and in satin, by a partner we know well and visit regularly.
