The 6 Best Duvet Inserts of 2023, scientifically proven

our bed is your daily retreat to rest, reset, and rejuvenate. A quality duvet insert plays a key role in how cozy and comfortable it feels. Fluffy and thick like a blanket, duvet inserts are white or neutral bedding basics that are meant to be used with a cover. While comforters are similar, they do not require a cover. When selecting a duvet insert, focus on practical considerations, such as fill material, shell material, warmth, construction, and care instructions.Duvet inserts can be filled with down made of soft and fluffy feathers from the undercoat of a duck or goose or down alternative materials, such as microfiber, polyester, cotton, or rayon, that replicate the feel of down. The shell fabric is most commonly cotton or polyester. There is a wide range of duvet covers to protect your duvet insert from dirt and body oils. If you take proper care of a duvet insert, it will last for years. You can switch out the duvet cover seasonally or as your tastes or trends change.“I always want my beds to feel like a luxury hotel bed, and a duvet will help you achieve that,” says Jessica Mintz, principal designer, and owner of Jessica Mintz Interiors, an interior design firm based in Los Angeles. “It’s also going to give the bed a more full look. You can layer it with a waffle bed blanket or quilted bed blanket—I like to fold it down so a third of the bed is covered by a fluffy folded-over duvet.”To find the best duvet inserts, we rounded up 34 inserts and comforters and put them through a series of rigorous tests in our home testing lab to evaluate their warmth, comfort, and ease of use, also taking into account shell material, fill, size options, and care instructions.
