The big distinction: duvets are typically meant to be paired with duvet covers, while comforters are usually used on their own. Duvet inserts are usually fluffier than comforters as well, and unlike comforters, most duvets are plain white, since you can easily jazz 'em up with a cute duvet cover.What is the best type of duvet insert filling?Alright, so you’ve got a couple different options, and it really boils down to your personal preference:Traditional, regular down filling typically consists of lightweight goose or duck plumage and feathers—it retains heat well, making it ideal for cold sleepers and winter months, and tends to be on the more expensive side.For the more budget-conscious (or vegan!), alternative down is usually made of synthetic materials like polyester. It’s a hypoallergenic option that shouldn’t trigger dust or dander allergies the same way regular down might.For those who are looking for more natural fill options, look for a duvet insert made with bamboo, eucalyptus, wool, or even silk, if you’re feeling splurge-y. Natural fibers tend to be more on the breathable side, so you’ll get the super plush effect of a duvet insert or two without overheating in the middle of the night!Advertisement - Continue Reading BelowHow much does a duvet insert cost?The cost of a duvet insert totally depends on the type and quality of the materials used. You can expect to pay more for real down or natural fibers than synthetic fills and shells. Luckily, the duvet inserts included in this article range from under $50 to over $500 for a queen-size duvet, so you can choose based on your budget. Some companies even offer a free trial period for you to sleep-test your duvet insert, so you can truly have peace of mind when committing to your final choice!How to choose the best duvet insert.Selecting a duvet insert is one of those things that is completely left up to personal preferences, but when shopping for the right duvet, here are some things to look for:Find the right weightDuvets are notoriously known for being pretty warm—which isn't exactly great for hot sleepers. But the good news is there are different duvet weight options to choose from, so if you tend to have sweaty snoozes but still want that fluffy duvet experience, then you can (literally) rest assured that there’s a lightweight or cooling duvet for you. Typically, you can find duvet inserts available in these weight levels: lightweight, heavyweight, or all-season.Lightweight options are great for warmer months and hot sleepers, while heavy duvets are fantastic for colder months and cool sleepers. And all-season duvets are exactly what they sound like—duvet blankets that are suitable for year-round use, thanks to their temperature-regulating fill. If you want to get really fancy with it, some companies offer two or three different weight options to really help you customize your sleep experience.Consider the care instructionsSince duvet inserts are meant to be put inside a duvet cover, they typically only need to get washed every four to six months. However! Spills can and do happen, and getting your duvet professionally laundered can be expensive (not to mention a pain). If you have pets or kids (or just happen to be v spill-prone), consider skipping the spot-clean-only or dry-clean-only duvets for something you can easily toss in the wash at home.Advertisement - Continue Reading BelowWhy trust 'Cosmo'?Not to brag or anything, but helping you (yes, you!) obtain The Perfect Night of Sleep™️ is one of our many specialties here at Cosmo.
