A quality comforter is a sleep essential. The best comforters are filled with lots of little air pockets to retain heat and enhance breathability. Since they come without a cover, they're wrapped in soft and stylish shells. A duvet is a lot like a comforter, only it's made up of two parts: the insert and the cover. 

Hot sleepers will appreciate a lighter layer, while a heavy-duty comforter might be more suitable for cooler climates. Down comforters are filled with real feathers, which trap heat to keep you warm in the winter, though vegans or allergy-suffers might prefer a down alternative option. In short, there are so many sorts of comforters that it can be difficult to find one that suits your sleep needs. 

That's where we come in. Our expert sleep editors know all the best places to buy comforters. After trying all the best duvet inserts, we've narrowed it down to our top nine to suit every season and sleep style. 

We've tested each of these comforters for months, if not years, to monitor their performance over time. We've ranked them based on comfort, sustainability, and ease of cleaning, as well as the all-important price.
