FAQs

How do I choose the right king size duvet?

Start with warmth. Lightweight (around 4 tog) for summer, mid-weight (7-9 tog) for spring and autumn, heavy (12+ tog) for cold winters. Then choose fill: down is lighter and loftier, synthetic is hypoallergenic and easier to wash.

A king size duvet fills a big bed. Getting the weight right means the warmth distributes evenly across the whole mattress without hot spots or cold edges.

What fill options are there for king size duvets?

Natural down (lighter, loftier, longer-lasting), down-feather blends (sturdier, slightly heavier), and synthetic polyester clusters (hypoallergenic, machine-washable). Each fill type comes in multiple warmth ratings.

Your choice depends on whether you prioritise warmth-to-weight ratio (down), easy care (synthetic), or a balance of both (blend).

What tog rating should I choose for a king duvet?

Tog measures warmth, not thickness. For most centrally-heated bedrooms, 9-10.5 tog covers autumn through spring comfortably. Buy a lighter one (around 4 tog) for summer and switch at the season change.

What's the difference between down and synthetic king size duvets?

Down is natural plumage: lighter for its warmth, plumper, and longer-lasting if cared for. Synthetic is polyester clusters that mimic down: cheaper, machine-washable, and good for allergies.

A king size duvet in down lasts ten to fifteen years. A synthetic king duvet lasts around five before flattening.

Where are Marshmellow king size duvets made?

Filled and finished in Portugal, in the same Lintexport mill we've been running since 1967. The shell is woven from our own Portuguese cotton. The fill is sourced and processed to European traceability standards.

How do I care for a king size duvet?

Air it out weekly to keep the loft up. Wash once or twice a year on a delicate cycle, ideally at a launderette with a large-capacity drum, since most home machines are too small for king size duvets.

Tumble dry low with clean dryer balls to redistribute the fill.

How long does a king size duvet last?

A well-made down king duvet, properly cared for, lasts ten to fifteen years. A synthetic king size duvet lasts around five before flattening.

The cost-per-year of a good king duvet is lower than people think. You just pay it up front.

Luxury King Size Duvets

A king size duvet fills a big bed. What fills the duvet matters.

More filling means more places where shortcuts show. Cheap king duvets sag in the middle, clump after a year, lose their loft under their own weight. A properly made king size duvet holds together for a decade.

Ours is filled and finished in Portugal, since 1967. Natural down for warmth without weight. Synthetic for easy care and allergy-friendliness. Both in summer, mid, and winter tog ratings.

A king duvet bought once and used for ten years is one of the better deals in the bedroom. Treat it well, air it out, and it stays plump.

Other king size duvets cut corners on fill power and shell cotton. Ours don't. Luxury king size duvets from a mill that makes the shell and fills the duvet under the same roof.

Made in Portugal, since 1967. Fill it properly.
