Beyond the M3: More Cooling Solutions for Every Sleeper While the Bedgear M3 sets a high bar, we know that one size doesn't fit all. The market is flooded with claims of `cooling benefits`, but we've sifted through the noise to bring you other tested and liked options that truly deliver.

Love your current mattress but hate the heat it traps? Don't buy a new one! The BedJet 3 offers a revolutionary `bed cooling device` that turns your bed into a personalized climate zone. For just $387, this `climate-control device` uses a powerful blower tucked discreetly under your bed to `blast hot or cool air` directly beneath your covers. It’s the perfect ticket if you’re a hot sleeper seeking `cool sleep without buying a whole new mattress`. Sealy Cocoon Chill Memory Foam Mattress: Cool Touch, Firm Support (Courtesy of Sealy) If you crave a mattress that feels `noticeably cool to the touch` from the moment you lie down, the Sealy Cocoon Chill is your answer. Its `exclusive phase change material` works like magic, `drawing and storing the body's heat` for a consistently cool surface. This `all-foam mattress` leans towards the firm side, making it an excellent `firm cooling mattress` choice for `back and stomach sleepers` who need robust support. Side sleepers seeking deeper contouring might look elsewhere, but if you’re a stomach sleeper wanting both firmness and cool, this one is a winner. Plus, our testing revealed `almost no motion transfer`, meaning you and your partner can shift without disturbing each other's precious sleep. Zinus 12-Inch Green Tea Memory Foam Mattress: Affordable Freshness

For an `affordable cooling mattress` that packs a punch, consider the Zinus 12-Inch Green Tea Memory Foam Mattress at just $281. This `dense behemoth` features 12 inches of layered foams, topped with a unique blend of `green tea and purified charcoal foam`. This isn't just for show; the `activated charcoal microparticles block moisture and odor`, helping maintain the mattress's overall `freshness over time`. It offers `cradling and conforming support` for `joints and spine`, though our tester with a smaller frame found it a bit too firm. Despite being `memory foam`, the infused materials `wick moisture` and `keep the bed cool` – a refreshing surprise! Casper Snow Hybrid: Living Up to Its Name When a mattress includes "snow" in its name, your expectations for `cooling effects` are naturally high—and the Casper Snow Hybrid, priced at $2,495, truly `lives up to that expectation`. This `hybrid cooling mattress` masterfully combines `poly foam, memory foam, and pocketed coils` to deliver superior `targeted support` at the hips, waist, and lower back, `alleviating pressure` points. This makes it an ideal `cooling mattress for back and stomach sleepers`. While it arrived slightly misshapen and emitted a faint plasticky scent, a couple of days allowed it to settle into its perfect rectangle, with the smell completely gone. Saatva Memory Foam Hybrid: Firmness, But Cooling Falls Short

(Courtesy of Saatva) The Saatva Memory Foam Hybrid, starting at $1,999, is `marketed as firm, and that's exactly what you should expect`. It features `patented AirCradle memory foam` with `concentrated cushioning in the center`, strategically designed to support your `lower back`. For our 5'2" tester, this middle-back cushioning didn't align perfectly. Despite incorporating a `triple-phase LuxeCool system` and `cooling gel-infused memory foam`, the overall `cooling effect didn't stand out` as much as other options on our list. Wayfair Sleep Series: Accessible Cooling for Every Budget (Courtesy of Wayfair) Wayfair offers a diverse range of **affordable cooling mattresses**, making innovative sleep technology accessible.

Its `quilted Euro-top knit cover` and sides promote `continuous airflow`, keeping you cool. Classic `pocket coils` provide structure and support, minimizing `motion transfer`. It boasts `solid edge support` and `adjustable base compatibility`. Ideal for `plush mattress` lovers, though its extreme softness might be `too plush for someone with a bigger body`. * **Wayfair Sleep 13.5-Inch Medium Cooling Gel Memory Foam Mattress ($340):** While listed as medium, this `13.5-inch cooling gel memory foam mattress` felt `super-plush` to us. Its top layers of `gel-infused memory foam` and `comfort foam` mold to your body, `relieving pains and achy joints`.

Your Cooling Mattress Buying Guide: Sleep Smarter, Not Hotter Navigating the world of cooling mattresses can be daunting. Here’s what we consider crucial when choosing your next sleep investment: * **Composition: The Core of Cool** Opt for `mattress materials` specifically designed to promote `airflow` and `prevent heat buildup`. Look for foams infused with `gel or copper`, which are engineered to `dissipate heat` away from your body. A `hybrid mattress` is often a fantastic choice, combining the best of both worlds: a `coil support system` under comfort layers of foam or latex. These tend to `retain less heat` than `all-foam mattresses` because the springs create crucial space for `airflow`. * **Cover Fabric: Your First Line of Defense** The cover is your direct contact with the mattress, so its material matters. Seek out `breathable mattress covers` made from `moisture-wicking fabrics` and `phase-change fibers`. These advanced materials `draw sweat away from the body`, regulating your temperature. Excellent options include `bamboo`, `Tencel lyocell`, and `synthetic fabrics` engineered for cooling. `Perforated cooling covers` and `quilted tops` further amplify `airflow` between your body and the fabric, creating tiny pockets for air to escape.

* **Airflow: The Breath of Your Bed** Proper `airflow` is non-negotiable for a truly cool sleep. It ensures that the heat your body generates overnight is efficiently conducted *through* and *away* from the mattress. While `hybrid mattresses with individual coils` are masters of this, many `cooling mattresses` employ `other tricks`, like channels and open-cell foams, to enhance ventilation. * **Firmness: A Surprising Factor in Heat Retention** While `mattress firmness` is often a `personal preference`, your choice plays a `crucial role in the way your body traps heat`. `Softer mattresses` tend to envelop your body more deeply, leading to `increased heat retention` as you sink into the surface. Conversely, `firmer mattresses` provide `better support` and allow for `more air circulation` around your body, keeping you cooler.

How WIRED Selects Models to Be Reviewed Our commitment to finding the `best mattresses` is extensive. We’ve `tested over 100 beds` across all our guides, from `Best Organic Mattresses` to `Best Mattresses You Can Buy Online`. Our team constantly `discusses mattress brands` – who we’re fans of, and who we're not. We also `scope out competitor reviews` to ensure we’re considering the full landscape. Crucially, `we pay for the beds we want to try` if a sample isn't available. We’re always willing to test mattresses from brands that approach us, but we pride ourselves on giving our `honest opinion` – we are never paid for glowing reviews on products that are just "mid." We make a concerted effort to test a `wide breadth of mattress types, firmness, and brands` to give you the most comprehensive and trustworthy advice on where to `invest your money` (and a third of your life) for optimal sleep. What Does WIRED Do With Mattresses After Testing?

Our top picks continue on to `longer-term testing` in our own homes and those of other staffers, friends, and family. Other tested models are responsibly `donated locally`. How Does WIRED Test Cooling Mattresses? Our `mattress testing process` is thorough. Each mattress is tested for `at least a week, but in many cases for longer` – often half a month or more to truly understand the product. We test them in `different seasons` and with `different types of sheets and bedding`. Beyond just sleeping, we perform active tests: sitting on edges for `edge support`, jumping for `bounce`, and evaluating `motion transfer`. Perhaps most importantly for this guide, our perpetually warm (and often `sweaty`) tester gauges abstract but critical aspects like `overall comfort at night`, how well `air flowed through the mattress`, and precisely `how much heat was trapped in`. Our goal is to simulate real-world usage so you can make an informed decision for truly `undisturbed sleep`.
