There are several key factors to consider when choosing the perfect duvet insert, with weight being one of the most important.  The weight of a duvet insert can greatly affect its warmth and comfort, so it's important to understand the different options available.  From ultralight to heavy-duty duvet inserts, each type serves a specific purpose and satisfies different preferences.

'Linen is exceptionally breathable and is a go-to for the summer months,' says Aja Tilghman, of Lulu & Georgia. 'It has an airy, breezy quality that will keep you cool and its natural fibers provide an effortlessly elegant look. Cotton percale is also a good option for hot weather as it is inherently cooler in nature and provides a lighter, crispier feel.'
