Quick Summary

Finding ideal bedding can be tricky if you’re a hot sleeper. On one hand, having a nice blanket or comforter can be cozy and inviting. On the other hand, if you already tend to sleep hot, having a comforter can cause you to sweat and overheat in the night. Thankfully, there are comforters that allow you to get some additional warmth and coziness without feeling like you’re spending the night in a sauna.

In this guide, we’ll share our top picks for the best cool comforters in several categories. Our comforter buying guide will also key you into the most important terminology and background information that you need to make an informed decision about the best purchase for you as a hot sleeper.

Cool Comforter Reviews

Nest Bedding Natural Cotton Comforter – Editor's Choice

  • Lightweight (2.8 pounds in Queen size)
  • 100% cotton shell and interior
  • 100-night sleep trial to test it out in your own home
  • Machine-washable

Our top pick is the Nest Bedding Natural Cotton Comforter that features high-quality cotton in both its shell and its fill. This natural cotton is airy and light and doesn’t trap heat in the way that a down comforter would. It has more limited loft and is thus lightweight, weighing under 3 pounds in the Queen size. This allows the comforter to give an added layer of warmth without leading to any kind of stifling heat.

If you are wary of even a light comforter like this, an added benefit is Nest Bedding’s 100-night sleep trial that lets you use the comforter for over 3 months with the option to return it for a full refund if you don’t like it.

Climabalance Down Alternative Comforter – Best Down Alternative

  • Mesh fabric improves breathability
  • In colder months, climate zones help retain heat
  • Fill made with hypoallergenic polyester
  • Machine-washable
  • Satisfaction guarantee with 30-day sleep trial

For the best option made with down alternative fill for hot sleepers, we recommend the Climabalance Down Alternative Comforter.

With a unique design that includes an array of mesh squares — also referred to as climate zones — this comforter is able to offer warmth in cooler times without causing overheating during summer months. The mesh gives plenty of breathability that allows for more rapid cooling, but there is still enough fill — with hypoallergenic polyester — to give you that necessary extra layer of heat when the mercury drops.

The blanket can be machine washed without causing damage, and it comes with a 30-day try out period that allows you to return the comforter for a full refund if it’s not to your liking.

Beckham Luxury Linens Goose Down Alternative Comforter – Fantastic Value

  • Quality design and materials at entry-level price
  • Fill with synthetic goose feathers
  • Reversible (2 colors) with numerous color choices to select from
  • 30-day sleep trial

If you’re on a tight budget or are just someone who is always looking to get the most bang for your buck, the Beckham Luxury Linens Goose Down Alternative Comforter is a great choice for hot sleepers. Its synthetic fill has the soft feel of down without the same amount of loft and insulation that would be found in most actual down comforters.

Each side of the comforter has a different color, allowing you to easily adjust the style and how it fits in your room. In addition, you have a handful of options with regard to which two colors your specific comforter will come in.

A 30-day sleep trial helps to protect your purchase in case you’re not satisfied even though the track record with this comforter is great. Given its bargain price, all these factors make this comforter our top choice for a fantastic value.

Buffy Comforter – Most Innovative

  • Shell made from soft and breathable Eucalyptus-based fabric
  • Eco-friendly fill composed of recycled plastics
  • Recycled polyester fill has loft but allows more airflow and cooling
  • No-risk returns during 30-night trial period

It’s rare to call a comforter innovative, but in the case of the Buffy Comforter, that term just simply fits the bill.

Both its shell and fill feature materials that you won’t find in virtually any other comforter. The shell is made from a fabric derived from Eucalyptus fibers, and it is naturally cooling and soft, a great combination for hot sleepers. The fill is derived from recycled plastics, and on average, each comforter removes 50 plastic bottles worth from landfills. The way that this recycled polyester is spun allows it to have both loft and lightness, so it can offer warmth but won’t make you sweat like a heavy down comforter.

If you’re into innovation and sustainability, this is a great choice, and if you’re skeptical about these new materials, the company offers a no-risk 30-night sleep trial.

PlushBeds Wool Comforter – Best Organic / Hypoallergenic

  • Shell made with 400 thread count sateen cotton
  • Natural wool fill that is chemical-free and cruelty-free
  • Wicks away moisture during warmer periods
  • Helps insulate and give warmth during winter

Wool is an incredible material because of its ability to regulate temperature. It insulates well and can provide meaningful warmth when the temperature drops, but what really sets it apart is that it remains breathable and moisture-wicking. The upshot is that when it’s hotter, the wool fill won’t overheat or cause you to wake up in a sweat.

As an added bonus, the wool that PlushBeds uses in this comforter is produced to high standards including being free of chemicals or animal cruelty. The wool is covered with a durable sateen cotton with 400 thread count to give the comforter a feel that is both soft and cooling.

Wool allergies are rare which makes this a great choice for people who are allergic to down but want a natural rather than a synthetic product.

Cool Comforter Buying Guide

What’s cooler than being cool? Knowing how to find the best comforter to keep you from sleeping hot. This guide walks you through what you need to know to make a great purchase.

How to Choose the Best Cool Comforter

Shell material

While a lot of focus is placed on the inner material in a comforter, the exterior — also known as the shell — cannot be ignored, especially for hot sleepers. The most common materials for comforter shells include:

  • Cotton: you’re probably familiar with cotton since it’s used in so many products including in clothing and bedding. Cotton shines when it comes to softness and when it’s produced to a high standard, it also is quite durable. Cotton can retain moisture, which isn’t ideal for hot sleepers, but some types of cotton, like sateen, have a smoother texture that feels more breathable.
  • Silk: silk is a fantastic material for hot sleepers because it does not retain heat and in fact can help a great deal with wicking away moisture. It’s also naturally soft and smooth, but unfortunately, it’s costly and tricky to keep clean, so it’s not employed as frequently in comforter shells.
  • Wool: wool is able to simultaneously be soft, warm, and moisture-wicking, and this is a combination that works well for hot sleepers. That said, because of its cost wool is less often found as a shell material, especially for comforters in the low-to-mid range price-wise.
  • Cotton-synthetic blends: sometimes cotton is blended with a synthetic textile (like polyester or rayon) to provide more moisture-wicking characteristics to the shell. These synthetics may also make it stretchier and/or more breathable.

Fill material

The fill material in a comforter will have the biggest impact on how much heat a comforter will retain, and as a result, it is a key point of emphasis for hot sleepers. The most important fill materials to be aware of include:

  • Goose down: taken from the underside of the plumage of geese, goose down is a powerful insulator. It is very lightweight and soft yet retains a huge amount of heat. These types of comforters tend to feel stifling to hot sleepers and given their price tag, usually are not a good choice for people with temperature regulation issues.
  • Duck down: like goose down, duck down comes from the underside of the plumage, but in this case of ducks. While it generally doesn’t have quite as much loft and warmth as goose down, it’s still far better suited for people who sleep cool rather than people who sleep hot.
  • Down cluster: the down cluster is the part of the down with the greatest insulating power. Down comforters with a high percentage of down clusters are the warmest, and as a result, should usually be avoided by hot sleepers.
  • Down alternative: down alternative fills take a number of different forms but are generally synthetic materials that are produced to be soft and light like down. Some are also made to have more loft and heat-retention power. Given their lower cost, down alternative comforters can be an attractive option for hot sleepers especially if there is not an abundant amount of fill.
  • Other feathers: only the material under the plumage is down, but there are obviously other feathers on ducks and geese. These feathers can be used to make comforters that are soft and light but not as lofty and warm as down. For hot sleepers who like the feel of a feather fill, this type is likely to be preferable to true down.
  • Cotton: cotton is affordable and soft and does not insulate at anywhere near the power of down. All of these make it a solid choice for hot sleepers even though in some cases cotton’s poor moisture-wicking issues can be an issue.
  • Wool: thanks to its natural temperature management properties — an ability to give warmth when needed and wick-moisture and breathe when needed — wool can be a solid bet for hot sleepers. The biggest downsides are its cost and weight.
  • Silk: a silk fill can work extremely well for hot sleepers because silk resists heat retention and is naturally airy and light, preventing it from feeling suffocating. However, silk can be expensive and may be out of the budget of many shoppers when it is used as the primary fill material.

Thread count

The thread count, used in describing the shell of a comforter, tells you how dense the yarns are within one square inch of fabric. If you’re not well-versed in sewing and textiles, it will suffice to know that higher thread counts normally indicate a shell that will feel smoother and that will hold up better over time. But it’s also important to know that thread counts can be manipulated to seem higher (through what’s known as “double counting” two-ply yarns in the material). For this reason, we advise looking for a thread count of 300-600 since counts higher than this probably are calculated using double counting.

Stitch design

There are various methods that are used to stitch together the various materials within a comforter.

  • Sewn-through: this technique uses stitching to connect the top and bottom of a comforter so that very small compartments are created that keep the fill from moving around within the comforter. It creates tighter compartments so that the comforter stays more compact, which prevents the fill from having more loft and insulation.
  • Diamond-quilted: this is usually a method of sewn-through stitching in which the stitches are in the shape of a diamond.
  • Gusseted: a comforter is gusseted if the top and bottom are sewn together around the exterior of the comforter. This does not have a huge effect on heat but can make the comforter feel more compact.
  • Baffle box: when the top and bottom are not sewn together directly but instead are connected with a smaller piece of fabric, it’s called baffle-box design. This gives the material a bit more room to move around within the compartments created by the stitches. This can necessitate fluffing a comforter more to redistribute the fabric. Having more space usually means more loft and heat, so this isn’t a primary feature for hot sleepers to look for.

Other Ways to Sleep Cool

Sleeping cool isn’t just about your comforter. There are a handful of other ways that you can optimize your sleep environment to prevent from overheating at night.

  • Choose the right mattress: Different mattress materials have huge variations in how much heat they tend to retain. For example, traditional memory foam is much more likely to contribute to sleeping hot than latex. Similarly, a very plush mattress that you sink into will be more prone to sleeping hot. For more on finding a great mattress if you’re a hot sleeper, check out all of our guides to buying a new mattress.
  • Cooling mattress toppers: If your mattress seems to sleep hot and you can’t afford to replace it, a cooling mattress topper, which goes above the mattress but under the sheets, may be able to help keep you from overheating.
  • Proper bedding: Your sheets and pillows can also affect hot much you’re likely to heat up in the night. Avoid heavy sheets (like flannel) or pillows made from one piece of memory foam that have a propensity to retain heat.
  • ChillPad: This is a mattress pad that has the ability to heat up or cool down your bed by circulating cooled or heated water through the pad.
  • BedJet: This device uses a hose to pump hot or cool air that can adjust the temperature of your bed and help to keep from sleeping too hot (or too cold).
  • Pajamas: Make sure not to wear heavy pajamas or other clothing that will hold in heat or restrict airflow around your body. Light and loose clothes — or limited clothes — are a far better bet.
  • Keep the thermostat low: Of course, the ambient temperature of your bedroom is going to have a direct effect on your body temperature when you sleep. Keep the temperature down (which research indicates may be good for you anyway) and consider using a fan to keep air moving.
