Whether you sleep cold or warm, the best king-size comforters create a cozy and comfortable sleeping environment. King-size comforters should measure more than 80 inches long by 76 inches wide, as this is the typical size of a standard king mattress. But the ideal comforter for you should also suit your personal sleeping preferences — whether you prefer a lightweight option to stay cool, a medium-weight pick for all seasons, or a thick and heavy option with plenty of fill for colder weather.
Before you choose a comforter, consider the materials used both inside and out. For the exterior, materials like cotton and bamboo are both soft and breathable, while polyester (often microfiber) is durable and budget-friendly, though not usually as breathable. When it comes to filling, your most common options are down, feathers, or a down alternative. Down comes from the plumage of ducks and geese, and goose down tends to be fluffier and warmer. Feathers provide more structure and less warmth. While down alternative is more budget-friendly, and a great option if you’re allergic to feathers or want to avoid animal products. It’s typically made from cotton, polyester, or rayon and can feel heavier than down.
While there’s no industry-standard way to rate warmth, most comforters are described as lightweight, medium weight (or all season), or heavyweight. Fill power is the best way to judge the warmth for down (and sometimes down alternative) comforters. Generally speaking, the higher the fill, the warmer the comforter; a fill power of 600 or higher will be toasty warm, and anything with lower fill will be better for slightly warmer weather. Alternatively, some comforters may list a GSM (aka grams per square meter) to describe the fill. The higher the GSM, the thicker and warmer it’ll be; a GSM of 500 to 700 is perfect for chilly nights.
These seven comforters are all available in king (and many other sizes, too!) to fit your bed perfectly. Bonus points — some even come with extra bedding pieces so you have everything you need for a good night's sleep.

3. A Reversible Comforter For Less Than $50
If you don’t want to fork over big bucks for a king-size comforter, this one from Homelike Moment is around $40; and honestly, it’s exceptional when it comes to quality for the price. But don’t just take my word for it; Amazon reviewers give this pick a knockout 4.7-star rating overall on the site after more than 10,000 reviews.
The comforter features an exterior shell that's made from durable microfiber polyester. And the inside is filled with 180 GSM of the same material, making this a lightweight option that’ll work well for warmer months. When temperatures drop, this comforter would also make a great layering piece — pair it with additional bedding for toasty warmth. A box-stitch design keeps the fill evenly distributed, so you won’t have to worry about it getting clumped.
While a duvet cover isn’t necessary with this pick, if you choose to pair it with one, there are four corner tabs to secure it.
Choose from a range of solid color options, the majority of which are reversible — so basically, two looks for the price of one! The king comforter is 104 by 88 inches in size, though other sizes are also available. Luckily, all sizes of the comforter are machine washable.
Enthusiastic Amazon review: "This was such a good buy! I’m impressed with the quality for such a low price. It is very light weight. I’ve washed it several times now and the material is not beading or pilling at all. Color is bright and true to pictures as well. Very pleased. It is better than what I expected at that low of a price."

4. A Luxurious Goose Down Comforter For Cold Sleepers
The pinnacle of luxury, this comforter from APSMILE will make you feel like you’re sleeping in a fluffy cloud — and who doesn’t want that? The outside of the comforter is made from a combination of soft Egyptian cotton and polyester (with a 400 thread count), while the interior is filled with premium goose down. The 750 fill power means this pick is heavy — the perfect comforter for naturally cold sleepers or when temperatures drop, though if you don’t need quite as warm of a comforter, this pick is also available in a medium-weight option for year round use. A 3D baffle-box construction keeps the fill evenly distributed.
In terms of care, it’s recommended by the manufacturer to spot clean or dry clean the comforter, so you may want to consider pairing it with a duvet cover that’s machine washable for easier in-between cleanings (eight corner tabs allow you to secure it in place).
The king-size comforter is 106 by 90 inches, though it's also available in Twin or Queen.
Enthusiastic Amazon review: "This comforter makes you feel like you are sleeping in a 5 star hotel and sleeping on a cloud. I used to have a very expensive cuddle down comforter and this is a 1/4 of the price of that one and is just as luxurious. The tie tabs help to hold it in place inside of the cover. For the night sleep I get with this I can’t believe the price tag isn’t higher."
- Also available in: Twin and Queen
