Bedding Experts Say Your Comforter Can Make or Break Your Sleep—These 7 Are the Best

In the Good Housekeeping Institute, we evaluate dozens of comforters and duvet inserts (terms that are often used interchangeably when you shop) each year. First, we inspect the comforters to get a sense of standout features and any construction concerns. Next, we coordinate at-home sleep testing with consumers to get real-life feedback. Here's what we consider when evaluating each comforter:

✔️ Craftsmanship: We inspect each comforter's construction for elements like stitching at the seams, corner loops or tabs for duvet cover attachment, and baffle-box vs. box-stitch designs. We also note how the fabric feels upon unboxing, whether any fill is poking through the material, and whether there are lingering odors. Analysts hold up the comforters to light (pictured here), which allows us to see if the fill is evenly spread out or has potential cold spots.

After testers complete their review, they also weigh in on whether the fill shifted during use or shed through the outer fabric. If they use a duvet cover, they note whether it was easy to attach to the comforter.

✔️ Washability: Lab pros consider whether the comforters can be machine washed and if they have special care instructions. We also ask at-home users to share their experiences with laundering the comforters.

✔️ Noise level: Some comforters are constructed with noisy outer covers, so we assess how quiet the fabric is when it moves. Consumer testers also rate the noise level after sleeping under the comforters.

✔️ Comfort: This is key when it comes to bedding, so we have our testers rate various aspects like overall comfort, the feel of the outer fabric, and overall satisfaction. They also provide answers to open-ended questions about anything they specifically liked or disliked.

✔️ Temperature: Our pros review cooling characteristics, and testers share whether they maintained a comfortable body temperature while sleeping under the comforter.

✔️ Certifications: We check whether the claims are validated by trusted third parties when relevant, like the Responsible Down Standard (which ensures ducks and geese are treated humanely), Global Recycling Standard, and Global Organic Textiles Standard.

✔️ Down standards: We also ensure that down products meet labeling standards for down and feathers, including like fill power and percentage of down in fill blends.

Down is often called the best material for insulation and fluffiness, but the truth is that the type of fill is a matter of personal preference. Here's how to choose which one is right for you:

✔️ Down: Not to be confused with feathers, down is a fluffy cluster from the undercoat of ducks and geese. It offers top-notch insulation because its lofty makeup traps air to provide warmth without weight. Down feels luxurious but costs more than down alternative fill and can sometimes be more difficult to clean. You can also find down-feather blends for a lower cost, but they won't be as fluffy.

If you shop for down, opt for one that's certified by the Responsible Down Standard to ensure the supply chain is properly traced. This verifies that the ducks and geese are not force-fed or live-plucked.

✔️ Down alternative: Typically made of synthetic polyester or regenerated cellulose fibers like Lyocell, this fill costs less than down and is a great option if you prefer to shop animal-free. Sometimes polyester can cause overheating, but newer constructions allow these materials to be more breathable and temperature-regulating. Down alternative is also typically easier to care for than real down, and you can sometimes find fills made from recycled plastic to reduce their environmental impact. Some brands use animal wool as comforter fill, which is inherently moisture-wicking and temperature-regulating but is often more difficult to care for, similar to down.

Besides the fill, here's what else you should keep in mind as you shop for your best comforter:

✔️ Stay-in-place construction: In order to prevent the fill from shifting around and clumping (which could result in cold spots), check for a baffle-box construction. This means there are vertical walls of fabric in the interior to help keep the fill in place. Less expensive comforters typically use a box-stitch construction, which means the sections are separated like a quilt. Oftentimes box stitching can be sufficient, but it can sometimes allow down fill to shift.

✔️ Down-proof materials: Most down comforters have 100% cotton outer fabric, and in those cases, the thread count can be an indicator that it's tightly woven to keep the fill from poking through. If the cover is cotton and the thread count is listed, look for one that's at least 300. With other outer cover materials like lyocell and polyester, thread count won't be as relevant, but these fabrics aren't typically paired with down fills so this isn't as much of a concern.

✔️ Fill power: Also specific to down, you'll typically see a fill power listed (just like you'll find on down-insulated winter coats). The higher the fill power, the more space the down clusters take up, meaning more air gets trapped to give you warmth without adding weight. If you're looking for good warmth in winter weather, we recommend a fill power of 600 or higher.

✔️ Warmth levels: Some comforters come in just one level, while others come in two to three options ranging from lightweight to all-season to extra warm. Typically a mid-level warmth is great for year-round use, but sometimes users prefer to swap out their bedding in the summer or winter months. The levels usually vary by the amount (or weight) of fill. Warmer comforters will have more fill, while cooling comforters will be more lightweight.

✔️ Care instructions: Some comforters are dry clean only, but all of the comforters in this article are machine washable. Just keep in mind that you may need to use large-capacity or commercial-grade machines because there should be room for the comforter to move around while it's washing and drying. It's also a good idea to use dryer balls and pause the drying cycle midway to manually fluff the comforter, which will help prevent clumps.

✔️ Cost: Our tests show that the best comforters typically fall in the $150 to $500 range. In general, the price of a comforter varies by size, materials, and warmth level. If you're looking to spend as little as possible, a polyester comforter (including the outer cover and fill) will be the least expensive. Ones with natural, luxury, and responsibly sourced materials (like cotton and down) can cost well over $300, but are certainly worth the splurge.

Technically, a comforter is intended to be used on its own, while a duvet insert is meant to go inside a duvet cover. Traditionally, comforters may be more decorative to be used on their own. That being said, the two terms are often used interchangeably while you shop. All of the comforters we recommend can be used on their own or inside of a duvet cover.

Stand-alone comforters skip the fuss of adding a duvet cover each time you wash it. On the flip side, using a duvet cover means you can wash just the cover—not the entire comforter—on a regular basis to keep it clean and protect it from wear and tear, helping it to last longer.
