If you're a hot sleeper, you've probably heard of Slumber Cloud. They've made a name for themselves with their incredible temperature-regulating bedding that uses Outlast®, a special technology originally developed for NASA to keep astronauts comfortable in space. It's science-backed comfort that helps you stop sleeping too hot or too cold.
For those of us who love Slumber Cloud's high-tech approach to a better night's sleep but are curious about what else is out there, you're in luck. Here are 19 other brands that deliver amazing cooling comfort, from active, tech-driven systems to natural, breathable fabrics.
1. ChiliSleep
ChiliSleep (formerly ChiliPad) takes cooling to the next level with its water-based systems. Their mattress pads, like the OOLER and the Cube, let you set a precise temperature from 55 to 115°F, actively circulating water to maintain your perfect climate. It's a more high-tech approach compared to Slumber Cloud’s passive Outlast® technology.
Prices range from around $399 to $799, making this a premium investment for anyone who wants total control over their sleep temperature. If Slumber Cloud helps manage temperature, ChiliSleep lets you dictate it entirely, making it ideal for those who need serious cooling power.

2. Eight Sleep
Eight Sleep is the tech enthusiast's dream bed. Their flagship "Pod" is a smart mattress cover that not only offers dual-zone cooling and heating but also tracks your sleep metrics - like heart rate and toss-and-turns - to adjust the temperature automatically. It's an all-in-one smart sleep system, with prices for the Pod cover starting around $1,699.
While Slumber Cloud focuses on fabric science, Eight Sleep is all about data-driven, automated comfort. It's a significant step up in technology and price, perfect for anyone who loves optimizing every aspect of their life, including their sleep.

3. Sleep Number
Known for its customizable air-chamber mattresses, Sleep Number also offers excellent temperature-balancing innovations. Their mattresses allow you to adjust firmness on each side of the bed, and many models feature advanced cooling layers. You can also buy their temperature-balancing sheets and mattress covers separately.
Unlike Slumber Cloud's standalone textiles, Sleep Number's cooling features are often part of a whole-bed ecosystem focused on personalized firmness and smart technology. It's a great choice if you’re looking for adjustability in both support and temperature.

4. Casper
One of the original bed-in-a-box pioneers, Casper focuses on cooling through material innovation. Their mattresses, especially the Wave and Nova Hybrid models, feature "Snow Technology" with specialized cooling gel and breathable foams to pull heat away from the body. They also sell Hyperlite sheets designed for maximum airflow.
Casper offers a more accessible, retail-friendly approach to cooling compared to Slumber Cloud's niche technology. If you're looking for an overall comfortable and cool-sleeping mattress and bedding setup, Casper is a one-stop-shop.

5. Tuft & Needle
Tuft & Needle keeps things simple and affordable without sacrificing quality. Their mattresses are engineered with adaptive foam that's infused with graphite and ceramic cooling gel to wick away heat, providing a comfortable sleep without complex tech. Prices for a queen mattress are often under $1,000.
If you find Slumber Cloud's space-age tech interesting but prefer a more straightforward, budget-conscious solution, Tuft & Needle is a fantastic alternative. Their focus is on creating a fundamentally breathable and cool foam mattress from the ground up.

6. Purple
Purple’s standout feature is its proprietary GelFlex Grid, a hyper-elastic polymer grid that flexes to support your body while allowing for incredible airflow. The open-channel design means heat has nowhere to get trapped, making it one of the most naturally cooling mattresses on the market. Mattresses start around $999.
This is a completely different approach to cooling than Slumber Cloud's fabric treatment. Instead of absorbing and releasing heat, Purple's design prevents it from building up in the first place. It's perfect for those who want both pressure relief and constant ventilation.

7. Luma Sleep
Luma Sleep combines the natural breathability of Talalay latex with the smarts of phase-change materials in their bedding. Their mattresses are designed for a temperature-neutral sleep experience, making them comfortable for both hot and cold nights. Mattresses are in the $1,000 to $2,500 range.
Luma offers a more design-focused feel with a deep emphasis on material craftsmanship. Think of it as a blend of Slumber Cloud's cooling-fabric concept with the plush, natural feel of high-end latex beds.

Engineered for people with an active lifestyle, Bear Mattress designs its products for muscle recovery and cool sleep. Their mattresses use Celliant® covers and cooling gel memory foam to dissipate body heat and help you wake up feeling refreshed. Mattresses start around $699.
Bear shares Slumber Cloud's focus on innovative textile technology but frames it around performance and recovery. If you're an athlete or someone who wants their sleep to be as restorative as possible, Bear is an excellent choice.

9. Brentwood Home
For those who prefer a natural approach to cooling, Brentwood Home is a top contender. The brand uses certified organic and natural materials like wool, latex, and cotton, which are inherently breathable and moisture-wicking. Their mattresses deliver cooling through smart, eco-friendly design rather than synthetic-based technology.
This contrasts with Slumber Cloud’s high-tech materials, offering an organic alternative that achieves a similar cooling effect. If you value sustainability and a clean, non-toxic household, Brentwood Home’s products align perfectly.

10. Avocado Green
Avocado is another leader in the eco-friendly bedding space. Their mattresses are handmade in California with GOTS-certified organic cotton, wool, and latex. These natural materials work together to create an incredibly breathable sleep surface that wicks away moisture and regulates temperature without any chemicals or cooling gels.
While Slumber Cloud solved the problem of sleeping hot with modern technology, Avocado Green solves it with the best materials mother nature has to offer. It’s a luxurious, sustainable choice for hot sleepers who prioritize health and the environment.

This means you can get the benefits of a weighted blanket without overheating.

It’s a very similar philosophy to Slumber Cloud - using fabric science to solve sleep problems. However, SHEEX is for someone who wants their bed to feel like their favorite performance t-shirt, offering unparalleled softness, stretch, and moisture management.

Molecule designs its mattresses, toppers, and sheets with a singular focus on achieving restful, recovery-focused sleep. Endorsed by athletes like Russell Wilson, their products are "Air-Engineered™" to maximize airflow and dissipate heat. The foam structure and cooling covers work together to regulate your core body temperature overnight.
Similar to Bear, Molecule speaks to the performance-minded sleeper. But its intense focus on heat dissipation through material structure makes it a strong contender for anyone who appreciates the scientific approach that Slumber Cloud is known for.
