Man-made GlacioTex vs natural latex: which is the more effective cooling mattress material?
GlacioTex and latex are both used in cooling beds to assist temperature regulation. If you're deep into researching which of this year's best cooling mattresses to buy, you've likely come across various celestial-sounding materials including these two. Luckily, we're here to help you understand what these materials are and what they bring to your sleep health. It is literally my and my team of mattress testers' job to shift through mattress jargon and marketing waffle to help you find the best mattress for you and your sleep needs, and snap up the best deal in monthly mattress sales. Here we're zooming in on latex and GlacioTex, pitting them against one another in terms of price, design, feel and temperature control to help you decide which luxury mattress material is worth the splurge. GlacioTex is a man-made fabric composed of fibers with high thermal conductivity. Usually sewn into mattress covers, these fibers are able to pull heat away from the mattress surface and, therefore, your body while you sleep. It is also hypoallergenic and waterproof, providing a defense against spills, dust mites and bacteria building up in your bed. While nobody has patented latex, brands under the 3Z umbrella (we're talking Helix, Brooklyn Bedding and Nolah) commonly use GlacioTex in their mattress covers. While there are two types of latex foams (natural and synthetic), it is the natural form we are focusing on here. Natural latex is a foam derived from sap from rubber trees and manufactured into an open-cell foam. The sap is extracted from the tree, mixed with non-toxic materials, whipped until frothed, and then set into a foam. The next step determines whether the natural latex will be Dunlop or Talalay latex. With Dunlop latex, the froth is poured into a mold all the way to the top, then baked, removed from the mold, washed and then baked again. With Talalay, it only partially fills the mold, which is then vacuum-sealed so the liquid expands. Then it's frozen, baked, washed and dried. The result? Talalay has a softer, spongier feel offering the sleeper more cushioning. On the other hand, Dunlop is denser and firmer, providing a more responsive, robust surface. Latex can be found in most of the best organic mattresses and in luxury mattresses like the Birch Luxe Natural mattress and Saatva Latex Hybrid mattress. From the manufacturing process to how they feel when you sleep on them, these materials have several differences, which we will explore here… Firstly, it is important to note that GlacioTex is actively cooling — it pulls heat away from the body to cool you down. Meanwhile, latex is breathable and temperature regulating, meaning it keeps the bed temperature-neutral. While memory foams are notorious for trapping heat, latex is porous and the tiny air pockets allow air to circulate freely. This means heat and moisture are able to escape rather than getting sucked into the foam and trapped against your body. On the other hand, GlacioTex employs high thermal conductivity fibers which transfer heat away from the air and your body. This means GlacioTex fabric remains cool to touch. GlacioTex fabric is typically a 50/50 blend of polyester and polyethylene with high thermal conductivity fibers sewn into it to form a cool mattress or mattress topper cover. These thermal conductivity fibers are able to dissipate heat through the mattress surface. On the other hand, latex foams are used in support and cushioning layers of mattresses. With slight discrepancies between Dunlop and Talalay mentioned above, latex is typically a firm, sturdy foam. Used in top comfort layers and support cores of a mattress, latex has a much larger effect on the overall comfort of a mattress compared with GlacioTex, which is usually only in the thin mattress cover. As a spongy material, latex is known to be durable and bouncy. This property makes it ideal for combination sleepers who like to switch between positions during the night. Firmer than memory foam, it contours to your body while providing spinal support. Meanwhile, our mattress testers have found GlacioTex covers to be slippery in come cases, making it difficult for a fitted sheet to stay put. Besides this minor inconvenience, the GlacioTex doesn't alter the feel of the mattress too much. It simply adds a cool-to-touch surface. As premium mattress materials, neither GlacioTex or latex come particularly cheap. As a natural material used in many of the best organic mattresses you can buy, latex is pricey due to its natural production process. GlacioTex is often available in cooling cover upgrades (Helix GlacioTex cover starts from $187 in a queen size at Helix), incurring extra cost. But it is generally cheaper than latex. While both GlacioTex and latex can contribute to a cooler sleep experience, as we've explored here, latex is generally considered more effective for temperature regulation. This is mainly due to the fact that latex's open cell structure allows air to flow throughout the mattress, improving breathability even in deeper layers. Whereas, limited to the mattress cover, GlacioTex primarily focuses on surface-level cooling. While it can initially feel cool, GlacioTex may not be as effective at dissipating heat trapped within the mattress. In essence, if you're looking for a material that actively regulates temperature and keeps you cool throughout the night, latex is a better choice. If you're primarily concerned with surface-level cooling and a cool-to-the-touch feel, GlacioTex could be a suitable option, but it's less effective at long-term temperature regulation.

7 big Prime Day cooling mattress topper deals ending tonight — beat the heat from just $38
There are still plenty of sleep deals around as Prime Week comes to an end, so what better way to enjoy a comfier night for less than by picking up a cooling memory foam mattress topper in the sales? Amazon is still full of Prime Day discounts on bed toppers, but many brands behind this year's best mattress toppers (and top-rated mattresses) are hosting their own rival sales, too. Budget brand Lucid has now launched a 30% off sitewide sale, which means you can now buy a Gel Memory Foam Mattress Topper for as low as $37.49. Cooling memory foam mattress toppers provide the soft, body-hugging comfort of memory foam without the stuffy heat-trapping tendencies. So I suggest grabbing these mattress topper deals before this month's Prime Day mattress sales come to an end. 1. Lucid Gel Memory Foam Mattress Topper: twin was from $49.99 now from $37.49 at LucidAs soon as Prime Week started, Lucid kicked off its 30% off sale, and it's brought some absolute bargains. We hailed Lucid's signature foam topper as the best cheap bed topper in our Lucid Gel Memory Foam Mattress Topper review, as its ventilated design and heat-drawing gel infusion offer great temperature regulation for the price. We think this sitewide sale will end when Amazon's does, so grab a 2" queen size for $52.49 (down from $69.99) while you still can. 2. Linenspa Memory Foam Mattress Topper: twin was $39.99 now $33.99 at AmazonThis memory foam mattress topper has gained a 4+ star score (out of an impressive 129,000+ ratings) on Amazon, and has already sold out over at Linenspa's official website. The topper is infused with cooling gel to regulate temperature and reduce the risk of night sweats. Right now, a queen is $50.99 (was $59.99) thanks to a 15% Prime Day discount. 3. Serta ThermaGel 3" Memory Foam Mattress Topper: twin was $69.99 now $45.49 at AmazonBoasting a 4.3 star rating, the Serta ThermaGel is brought to you by hotel-favorite brand Serta. Its trademark THERMAGEL features cooling particles and the memory foam is deigned to dissipate heat and improve airflow for a cooler sleep. With 20% off a queen is down to $75.92 from $94.99. 4. Helix Premium Mattress Topper with GlacioTex: twin was $373.33 now $272.54 with code TOMS27 at HelixAt 3.75" thick, this hybrid topper impressed reviewers in our Helix GlacioTex Premium Mattress Topper review with its comfort-boosting thickness and excellent cooling features. Its cover is made from heat-dissipating GlacioTex (often found in the best cooling mattresses) and its layer of microcoils improves airflow. Thanks to our exclusive TOMS27 discount code, a queen is now down to $364.03 (was $498.66).This Helix mattress deal is set to end soon, though. 5. Casper Comfy Mattress Topper: twin was $199 now $159.20 at CasperOkay, I admit this isn't billed as a cooling mattress topper per se, but just read our Casper Comfy Mattress Topper review. This topper's perforated foam and soft-knit cover was more than enough to keep testers cool, and it's a great alternative to buying one of our picks in our best mattresses for side sleepers guide. Oh, and did I mention that it's hardly ever more than 10% off? So this Prime Day-rivalling 20% discount that reduces a queen to $239.20 (was $299) is a big deal. 6. Tempur-Adapt + Cooling Topper: twin was $329 now $279 at Tempur-PedicWhile the original Tempur-Adapt Topper was super comfortable, testers found it slept rather warm. However, this cooling upgrade (which costs an extra $60) gave testers for the Tempur-Pedic Tempur-Adapt + Cooling Mattress Topper review much cooler sleep with the same amount of comfort. There's now a 20% off sale at Tempur-Pedic, taking a queen to $359 (was $429). (You could also try the 40% discount code TOPPERS40, which sometimes gets me 40% off if I'm lucky.) 7. Sleep Innovations Cooling Comfort Gel Memory Foam Dual Layer Mattress Topper: twin was $109.99 now $75 at AmazonSleep Innovations' Dual Layer Mattress Topper is insanely popular on Amazon, with 4.4 stars and 32,000+ ratings.

A queen size is now 23% off and down to $115.99 (was $149.99) in Prime Day deal.

If you're looking for a good deal on a cool bed then the Copperflex Pro Hybrid at up to $480 off at Brooklyn Bedding is worth a look.

Let's take a closer look at the deal now and see how it compares to this month's top mattress sales... Brooklyn Bedding Copperflex Pro Hybrid: twin from $932 now $652.40 at Brooklyn BeddingI rate the 14" Copperflex Pro Hybrid as the best cooling mattress under $1,000 for a queen. It's built with heat conducting copper-infused foams and a GlacioTex cover cover that wicks away heat. Individually encased coils deeper in the mattress allow air to circulate freely, cooling down the bed. As for comfort, there's a pillow top for ample pressure relief and three zoned lumbar support.
