In its very best state, a down duvet is a soft, fluffy cover to cuddle up beneath to a chilly night. If the duvet gets damp or flattened from lying or sitting upon it, it feels lumpy, together with the down inside redistributed into clumps and gaps. To revive that clumpy duvet, shake it and air it out once in a while.
Shake Your Own Duvet
Shaking a duvet fluffs up a number of those flat spots and removes clumps. While creating the bed each day, grab 1 corner of this duvet and vigorously shake it as you smooth it back onto the bed. Should you feel clumps through the material, smooth them out with your hands.
Light and Fluffy
Airing the duvet outside on a sunny day also can help revive the down inside, as bedding builds sweat and moisture out of use. Hang the duvet on a clothesline or above a porch railing following first shaking it out. Moisture trapped inside the duvet disappears when exposed to dry air and sunshine. For best results, always use a duvet cover to keep the duvet its safest.
