HARMONIE duvet – cotton cover, 150 or 300 g/m²

At the end of a busy day, few things feel as inviting as a freshly made bed and a duvet that suits the way you sleep. HARMONIE lets you choose between a lighter feel and a more generously filled duvet, without changing the reassuring simplicity of a cotton cover.

Lightweight or temperate: choose your 150 or 300 g/m² duvet

The 150 g/m² version is the lightweight option. It is worth considering if your bedroom tends to be warm or you prefer less filling around you. The 300 g/m² version is described as temperate and contains more filling. Rather than choosing by season alone, think about your bedroom temperature and whether you usually feel hot or cold at night.

Both are available in 140 × 200, 200 × 200, 220 × 240 and 240 × 260 cm. A wider duvet may give you a more comfortable drape on either side of the bed, especially if two people share it. Check your mattress measurements and the overhang you enjoy before selecting a size.

Cotton on the outside, carefully specified filling inside

HARMONIE has a 100% cotton cover and a filling made of 100% polyester siliconised hollow fibres. The technical information describes the filling as having an anti-dust-mite and antibacterial treatment based on linseed oil. This describes a textile treatment; it is not a promise that the duvet will eliminate allergens or bacteria in your bedroom. The duvet has a bias-bound finish and is made in France.

A cosy bedroom that feels like yours

Slip HARMONIE inside a duvet cover in calming, natural colours, or brighten your bed with patterned pillowcases and a contrasting throw. Your duvet provides the filling and comfort; the colours and textures around it create the mood. Choose a cover in the same dimensions as the duvet for an easy fit.

Mamimosa’s care tip

The supplied care instructions recommend a delicate wash at 40°C with reduced spin. Before washing, check the label and make sure the drum has enough room for the duvet to move freely. Follow the label for drying, too, rather than assuming that every filling tolerates the same treatment.

Is this duvet made in France?

Yes. All eight sizes and filling weights in this HARMONIE range are listed as made in France.

How should I wash it?
