In-Depth Review and Process

There are a lot of things that contribute to a good night’s sleep. Your pillow and sheets matter, but if there’s one item that can make or break your night, it’s your comforter. A great comforter keeps you at the right temperature and actually helps you relax into deeper sleep.

Cooling comforters take this a step further by actively managing heat and moisture so you don’t overheat or wake up damp. Even if your mattress and pillow are dialed, the wrong comforter can trap heat and undo everything. The right one keeps you cool, dry, and comfortable all night.

I tested 7 of the most talked‑about cooling comforters to see which ones truly delivered. I ranked each on:

• Cooling Performance
• Comfort
• Quality
• Customer Service
• Value

For me, the best cooling comforter should keep me from overheating, feel great against the skin, and justify its price. I’m not trying to pinch pennies on something I use every night, but I also don’t want to pay for gimmicks.

The ideal pick relies on real, proven materials—things like phase‑change technology (PCM), TENCEL™ lyocell, and breathable weaves—that actually regulate temperature and wick moisture. That’s what I looked for, and that’s how I scored each one.

Things to Look For in a Cooling Comforter

• Temperature regulation – helps prevent overheating, not just at first touch, but throughout the night. Look for fabrics and fills that allow airflow and keep your body temperature steady.
• Cooling that lasts – many comforters feel cool at first but warm up quickly. The better ones use materials designed to regulate heat for hours, not minutes.
• Comfort and feel – beyond cooling, pay attention to how the fabric feels. Some shells are smooth and silky, others more textured. Choose what you’ll enjoy against your skin night after night.
• Moisture control – especially important for hot or humid sleepers. Moisture-wicking fills pull humidity away from the skin so you stay drier and more comfortable.
• Warranty and trial period – a comforter is a long-term investment. Look for products backed by strong guarantees and home sleep trials so you can test them without worry.

Things to Avoid

• Cheap synthetic fills – often trap heat, lose their loft, and wear down quickly after a few washes.
• “Cooling” marketing without substance – some products are labeled cooling but don’t actually use materials that regulate temperature. Always check how the effect is achieved.
• Rough or noisy shells – fabrics that feel scratchy or crinkle when you move may be inexpensive, but they won’t improve your sleep.

Are Comforters Under $100 Worth Considering?

Sometimes, but usually not for the long term. Budget comforters can be fine as a short-term solution and may feel cool at first. But to keep costs low, they often cut corners on materials and construction.

• Cooling effects often fade after a few washes.
• Cheap fills can clump, flatten, or lose softness quickly.
• You may end up replacing it sooner, which costs more in the long run.

Investing in quality pays off. A well-made cooling comforter can last for years, regulate temperature more effectively, and help you wake up feeling consistently rested.

The Final Winner:

Runner Up: Rest Evercool Cooling Comforter

The Rest Evercool was the best of the non-Dosaze group for me. Right away, I noticed how incredibly soft and smooth it felt against the skin. It’s clear that it uses real TENCEL™ in the fill, and that makes a big difference—there’s a silkiness and breathability you just don’t get with basic polyester. I appreciated how well it draped across the bed and conformed around me, making it feel genuinely luxurious.

Cooling performance was good. While it doesn’t have PCM or active heat-absorbing technology like the Dosaze, the Evercool fabric is lightweight, breathable, and moisture-managing, which helped keep me comfortable through most of the night. I also liked that it has a balanced feel—not too heavy, not too light—so it works year-round. My one critique is that it doesn’t stay as consistently cool as the ThermaCool, but for someone who wants a silky, high-quality comforter without paying top dollar, it’s a very strong choice.

All-Natural Pick: Birch Natural Down Duvet Insert

The Birch Natural Down Duvet Insert stands out for taking a completely different approach. Instead of modern cooling fills, it’s packed with high-quality, responsibly sourced down and wool. That gives it a fluffy, lofty feel that’s cozy and natural, rather than silky or “technical.” The craftsmanship is obvious, and it has a high-end, hotel-like presence on the bed.

Where it shines is for people who care about natural materials and sustainable sourcing. Down and wool both provide excellent insulation and breathability, and the duvet insert is very well-constructed. However, this isn’t what I’d call a true “cooling” comforter. It sleeps a little warmer than the others, and I doubt it would hold up as the best choice for hot summer nights. That said, if you’re someone who values organic materials and wants a natural lofted duvet that feels luxurious, it’s a great fit. For cooling performance specifically, it lags behind the PCM and TENCEL picks, but for eco-friendly comfort, it’s tough to beat.

Budget Pick: Elegear Revolutionary Cooling Comforter

Elegear really surprised me for the price point. At under $60 for a queen, it’s one of the least expensive options out there, but it genuinely does cool better than cotton or polyester basics. The Japanese Arc-Chill fabric has a cool-to-the-touch feel, and it’s lightweight enough to use even in warm climates. If you’re on a tight budget, it’s an excellent way to get noticeable cooling benefits without overspending.

That said, there are some tradeoffs. One side of the comforter uses brushed polyester, which has that “catch” sensation on hands and feet that I personally don’t love. Also, the fill inside isn’t the most durable. Every time I pulled on the comforter, I could feel the fibers shifting and, in some cases, almost tearing. It doesn’t have the longevity or premium construction of higher-end options. Still, for hot sleepers who want something affordable that actually cools, Elegear delivers more than expected. It’s not perfect, but at this price point, it’s hard to complain.

SlumberCloud UltraCool Comforter

The SlumberCloud UltraCool Comforter felt instantly soft and refreshing to me, and overall I really enjoyed using it. The nylon/spandex shell is silky and comfortable, and paired with NASA-developed cooling fibers, it definitely feels different from your standard down alternative. I noticed a nice balance between softness and structure, and it draped well without feeling too heavy.

Cooling performance was solid, and it really did feel comfortable through the night. My main drawback, though, was the fill. It uses a polyester-based fiberfill, and every time I tugged or shifted the blanket, it felt like the fill was separating or breaking inside. It doesn’t feel as durable or high-end as PCM or TENCEL-based options. That said, for couples or individuals who want a comforter that adapts to changing body temps, the UltraCool is still a strong pick. It’s machine-washable, versatile, and backed by a reputable brand. I just wish the interior felt as premium as the silky shell.

Sijo Cooling Eucalyptus Comforter

Sijo takes a more natural approach, using eucalyptus-derived lyocell both inside and out. The TENCEL™ fill is breathable, moisture-wicking, and eco-friendly, which makes it appealing if you prefer natural materials over synthetics. I appreciated that it didn’t trap heat, and as a lightweight duvet insert, it works well for people who want airflow and softness without the weight of down.

That said, the exterior shell just didn’t feel as silky as some of the others. Compared to the Dosaze or even Rest, it was noticeably less smooth against the skin. I found myself thinking it would be better inside a duvet cover—especially if that cover was also cooling. On its own, it’s fine, but not the most luxurious. Where Sijo shines is sustainability and breathability. If you want something eco-friendly, airy, and reliable as a cooling duvet insert, this one fits nicely. Just don’t expect it to wow you with a silky, luxe finish.

Buffy Breeze Comforter

The Buffy Breeze is another all-lyocell option, made with a shell and fill that are both derived from eucalyptus. I appreciated the eco-friendly approach and the fact that it felt noticeably lighter than some of the heavier alternatives. It’s breathable, comfortable, and well-suited for warm nights or summer months.

However, compared to the Dosaze or even the Rest Evercool, it lacked that silky, smooth exterior that makes some comforters feel more premium. I found it worked better as a duvet insert than as a standalone comforter, since the fabric itself isn’t as soft or luxurious as some others. That said, for people who care about sustainability and want something simple, lightweight, and effective at preventing overheating, the Buffy Breeze does a good job. It’s not as advanced in its cooling technology, but it’s a comfortable, eco-conscious option that holds its own.

Company Store Cool Zzz Temperature-Regulating Comforter

The Cool Zzz from The Company Store is a dependable, straightforward option. I appreciated the construction and the fact that they’ve incorporated phase-change material (PCM) to help regulate heat. It’s clearly well-made, and the company has a strong reputation for quality bedding, which is always reassuring.

That said, it doesn’t feel as silky or premium as the others. The cotton percale shell is sturdy but not smooth, and the polyester fill lacks the luxury feel of TENCEL™. While it does a good job of keeping the temperature more balanced than a standard down alternative, it didn’t feel as comfortable or high-end as the Dosaze or Rest. Still, if you want something durable, practical, and from a trusted brand, the Cool Zzz is worth considering. It may not be the most advanced or luxurious comforter here, but it’s reliable and solid for the price.
