The cooling mattress I'd buy just dropped to 40% off in a surprise 4th July sale
As an active runner, occasional hot sleeper and, of course, a mattress tester, if you asked me what mattress I'd pick without a budget in mind, my answer would undoubtedly be the Bear Elite Hybrid, which just dropped to 40% off all sizes at Bear with the code FOJ4TY. Packed with temperature balancing technology (we're talking Phase Change Material, copper foams, breathable coils and Celliant), my team of fellow bed testers and I rate the Bear Elite Hybrid as the best cooling mattress of the year. Regular mattress sales at Bear take 35% off the Elite Hybrid but this 40% off only appears around big-hitting sales like Black Friday and Memorial Day. Honestly, I didn't expect to see it in 4th July mattress sales and I doubt it will stick around long. So, go, go, go if you're in the market for a reliable cooling mattress this summer. Bear Elite Hybrid mattress (queen): was from $2,427 now from $1,456.20 at BearAfter 40% off, a queen Beat Elite Hybrid will set you back $1,637 with the Celliant upgrade or $1,457 without it (was $2,727 and $2,427 respectively). Like the very best hybrid mattresses you can get, there are three firmness levels to pick from with the Bear Elite making it suitable for most sleepers. While 40% is the best discount we see in Bear mattress sales, MSRPs appear to have risen lately, with a queen last month costing $2,305 at MSRP vs the $2,427 today. So the mattress isn't at its lowest ever price (though it's likely the lowest we'll see from now on). Still, 120 night sleep trial, limited lifetime warranty and free and fast shipping are included, making this an excellent review: ★★★★½ User score: ★★★★½ (based on 3,900+ reviews) First things first, to benefit from the Bear Elite's full cooling mechanism you must upgrade with the Celliant cover, which costs an extra $180 for a queen size after the current 40% discount. For this premium, you get a mattress that captures body heat and converts it into infrared energy that helps your muscles recover through the night while removing heat from the bed surface. This mattress also incorporates copper-infused foams which help to transfer heat away from the body to keep the surface of the bed cool. On top of this, being a hybrid mattress means there's plenty of airflow through the bed. The result? A mattress that's able to keep you call even during a Texan summer, according to our lead tester for the Bear Elite Hybrid mattress review. Brooklyn Bedding CopperFlex Pro (queen): was $1,332 now £932.40 at Brooklyn Bedding While a Bear Elite would be my ideal mattress, I'm currently sleeping on the Brooklyn Bedding CopperFlex Pro Hybrid due to its smaller budget. Today's Brooklyn Bedding mattress sale takes 30% off, bringing the queen size to $932.40 (was $1,332). Yet its quality, feel and features punch above this price point, as I explain in my Brooklyn Bedding CopperFlex Pro mattress review. And its perks (a limited lifetime warranty, 120 night sleep trial and free shipping) match Bear's despite its lower price. Our review: ★★★★ User score: ★★★★½ (based on 500+ reviews)

The Casper Snow mattress is perfect for hot sleepers and it's currently 30% off — not even Black Friday gets better than this
Are you a side sleeper struggling to sleep through summer nights? The Casper Snow Cooling Hybrid mattress could be just the sleep solution you've been searching for. You can now save 30% on the Snow Hybrid at Casper, cutting a queen size to $1,745 (was $2,495). Falling just short of our best cooling mattress of 2025 list, the revamped Casper Snow, which got a glow up in 2024, is an impressively capable temperature-regulating mattress. It's packed with innovative technology — including HeatDelete bands and Phase Change Material — to help you combat night sweats and hot flashes. The Casper Snow isn't always included in monthly mattress sales and the current discount is the best we've seen on this upgraded model. Here's why cool shoppers in search of the best mattress won't want to snooze on this deal... Casper Snow Cooling Hybrid Mattress: twin XL was $1,895 now $1,325 at CasperThe Casper Snow is an ideal mattress for side sleepers who overheat at night. It is medium-firm and comes with heaps of pressure relief and cooling technology. The Casper Snow mattress is lined with the brand's signature HeatDelete Bands: thin strips of material infused with thermal conducting graphite, which direct heat away from the sleeper. Meanwhile the cover is infused with Phase Change Material that pulls heat away from your body while you sleep, remaining cool to the touch. This Snow Technology promises 12+ hours of cooler sleep. Casper mattress sales don't run constantly like other retailers, but when the Snow is on sale, discounts tends to sit between 20% and 25%, with 30% off being reserved for major holidays. That said, last 4th July we saw just 15% off the Snow Hybrid. With Casper feeling more generous this year, now a great time to snap up a great deal on a mattress that will help you sleep peacefully through summer months. We don't expect to see this 30% off again at least until Labor Day in September, or even Black Friday. Our review: ★★★★User score: ★★★★½ (740+ reviews) The combination of pressure relieving foams and supportive coils is ideal for supporting side and back sleepers. There are three zones of responsive foams to keep your spine aligned and pressure points cradled. Our tester for our Casper Snow mattress review (2023) found the older version of this mattress was a tad too firm for side sleeping. But reviewers of the updated mattress say "it's super comfy for us side-sleepers (or about any position)," providing "the perfect balance between support and softness." One even writes: "My back simply stopped aching. Thank you Casper." Though lightweight side sleepers may prefer something softer, such as one of this year's best pillow-top mattresses, while stomach sleepers would be better off with something from our best firm mattress guide, we think the Casper Snow is perfect for average weight side and back sleepers who run hot at night.

Bed bugs have ruined our sleep for 60,000 years, new research reveals — 5 ways to keep them out of your mattress
Sleep is the great unifier and while our ancient ancestors didn't have to worry about excess screen time and bed rot, we do have at least one sleep disruptor in common: bed bugs. New research suggests that bed bugs are the earliest human pests, following us out of the caves roughly 60,000 years ago and booming as our population expanded into cities. And we haven't been able to shake them since. Researchers from Virginia Tech have been tracing the history of bed bugs back to a subset of the species detaching itself from bats and choosing humanity as their favorite food source. While the Last Glacial Maximum around 20,000 years ago (the ice age) saw a decline in the general bed bug population, the human-associated bed bugs bounced back. Sadly — or, perhaps, happily — the bat-following bed bugs haven't fared quite so well. And it turns out our oldest pests have weathered a lot to continue bothering us, thriving as we established cities, rejoicing as the population expanded and even surviving the emergence of powerful pesticides. Get instant access to breaking news, the hottest reviews, great deals and helpful tips. So is there anything we can do to actually get rid of bed bugs? On a global scale, it seems unlikely. They're incredibly hardy and we clearly taste incredible. In your own home? That's a different story and if the past 60,000 years have been good for anything it's developing new, effective ways to remove bed bugs. The best mattresses you can buy online are undoubtedly better for your sleep than a Neanderthal bed (cavemen didn't even have Phase Change Material) but they are still vulnerable to bed bugs. However, with these tips you can keep bed bugs from infesting your mattress. One of the most effective ways to get rid of bed bugs at home is with a hot wash — bed bugs are not a fan of excessive high temperatures. We recommend washing your bedding once a week to prevent stains and this regular cleaning schedule can also prevent an outbreak of bed bugs before it gets started. Use a 140°F wash for a minimum of 90 minutes and follow up with either a hot dry cycle or a few hours in direct sunlight to eradicate bed bugs and their eggs. And when your sheets are drying, leave your mattress bare to allow it to breathe. This air flow helps trapped moisture dissipate and clears the enticing scent of you that attracts bed bugs to your mattress. Bed bugs are consummate hiders: they're tiny, fast and love the dark. That means the seams and crevices of your mattress are perfect bed bug homes. But the piles of laundry lying around your bed are equally attractive hideouts. If you want to limit the areas for bed bugs to lurk, keep the space around your bed clean. Just think, if Grug had only tidied his mammoth skin tunic away, we might not have to think about bed bugs at all... It's a common misconception that bed bugs are attracted to mess. They're just as happy in a clean mattress as a dirty one. However, keeping your bed clean does help you avoid bed bugs. Vacuuming your mattress can remove visible bed bugs as well as other pests and allergens that might be lurking in your bed. A thorough vacuum also presents an opportunity to check for bed bugs. As mentioned, they're exceptionally good at hiding which means you might not be aware of a problem until it's a full blown infestation. So when vacuuming keep an eye out for common signs of bed bugs, such as red or brown stains, eggs or discarded shell cases in the seams. Bed bugs have followed humans as we've spread across the globe — they're one of our most reliable travel companions. If you've been subject to a bed bug outbreak at home, there's a good chance they're an unwelcome souvenir from a trip away. You can avoid bringing bed bugs home with you by being alert, checking new beds for signs of pests and washing your clothing as soon as you get home. Research suggests that the creation of chemical pest control DDT (dichloro-diphenyl-trichloroethane) contributed to a massive crash in bed bug population but it quickly bounced back (...yay.) However, there are chemical bed bug killers such as CrossFire that have proved effective at eradicating an outbreak, while diatomaceous earth is commonly used as pest control. Other preventative tools such as bed bug glue traps can help you stop bed bugs as they make their way to your mattress. But for a serious infestation, it might be time to call in the professionals. Otherwise, here's to another 60,000 years hand in hand with bed bugs.

This luxury cooling mattress from Brooklyn Bedding helped me sleep cool during a heatwave — and it's back down to its lowest price in the Memorial Day sales
The Brooklyn Bedding CopperFlex collection is designed to bring hot sleepers cooling relief, and a taste of luxury, at a more affordable price to other luxury mattresses. (Think just under $1,000 for a queen, rather than $1,500-plus.) The flagship model in the range has just returned to its lowest price ever: with 30% off for Memorial Day, you can now get a queen CopperFlex Pro Hybrid for $932.40 (was $1,332) at Brooklyn Bedding. That's over $60 cheaper than its usual sale price in the Memorial Day mattress sales. I'm a huge big fan of this copper-infused mattress. I gave it 4.5 out of 5 stars in my Brooklyn Bedding CopperFlex Pro Hybrid mattress review: it's built with high-quality materials and supports most sleep styles well. And it's the new kid in our best cooling mattress guide, taking the spot for best cooling mattress under $1,000. (The bigger king size does cost just over $1,000, but the queen size and smaller are less than a grand.) Brooklyn Bedding CopperFlex Pro Hybrid mattress: twin from $932 now $652.40 at Brooklyn BeddingI slept on this mattress for over a month and I'm confident in saying it's a great option for hot sleepers — even more so now that it's back to its lowest price ever for Memorial Day. Packed with cooling technology like a cool-to-touch Phase Change Material (PCM) cover, copper foams and 760 individually encased coils, this breathable mattress helps you regulate your body temperature through the night by absorbing excess heat. For Memorial Day, the Brooklyn Bedding mattress sale has reached its peak, knocking 30% off everything on the site. This cuts a queen size to $932.40 (was $1,332), which is over $60 cheaper than its usual sale price and outstanding value for a quality cooling mattress. I slept on a full size 14-inch CopperFlex Pro Hybrid, which costs $839.30 in the Memorial Day sales (full price is $1,199, although it's always sold with some sort of discount) and I recommend it to hot sleepers, combination sleepers and anyone who sleeps on their side. All the options in our best mattress 2025 guide are built with reliable materials that are designed to help you get quality sleep. But few mid-range hybrids cost under $1,000 for a queen size. That's great value in itself, and it makes the Brooklyn Bedding CopperFlex Pro stand out as one of the best hybrid mattresses you can buy. Like its rivals, it comes with free shipping, plus a 120-night sleep trial and lifetime warranty.

What are Phase Change Material and GlacioTex cooling mattress fabrics and how do they work?
You're most likely to come across Phase Change Material (PCM) and GlacioTex when you're shopping for a cooling mattress, and in some instances luxury cooling bedding, toppers and pillows. On the surface both PCM and GlacioTex serve the same purpose: to keep you at an ideal temperature while you sleep by wicking away excess heat. But when you dig into the science behind these cooling material technologies, there are some differences that could affect your quality of sleep. Here's what you need to know about PCM vs GlacioTex, how each works, and what their benefits and drawbacks are for different types of sleeper. Phase Change Material (PCM) is a substance that helps regulate your sleep temperature by acting as an in-bed heat reservoir. In mattresses, PCM tends to be in wax or gel form. The particles are coated with a protective shell and embedded in foams and fabrics without leaking. PCM adsorbs and releases heat as its particles change from a solid to a liquid state. When the particles change from solid to liquid, they absorb heat and then they solidify when this stored heat is released. PCMs are often embedded in comfort foams or woven into mattress covers. These materials can be found in many of our top-rated cooling mattresses including the Bear Elite Hybrid mattress, the Brooklyn Bedding Aurora Luxe mattress, and the Tempur-Pedic Tempur-Breeze mattress. PCM is a versatile material that can be incorporated into various components including foam layers and fabric covers without major manufacturing hassle. These materials offer active temperature balancing as they adjust state according to your body temperature changes through the night. This means they can both absorb heat (drawing it away from the body) and release heat (warming up the body). A study assessing mattresses with PCM using a thermal and perception test showed mattresses composed of PCMs better facilitate human heat dissipation and result in a cooler perception and greater thermal comfort compared to conventional mattresses after 20 minutes of use. A downfall of this material is it has a limited heat-absorbing capacity. This means, once it is fully liquefied, it cannot absorb excess heat, reducing its cooling effect. While there is some scientific data backing PCM in mattresses, as referenced above, research is limited at this point. ✅ Your body temperature fluctuates through the night: PCMs offer dynamic temperature regulation, meaning they actively adsorb and release heat to maintain a neutral sleeping temperature, which is useful for people who sleep hot or cold at different points of the night. ✅ You want dynamic climate control without tech: Temperature regulating smart beds digitally heat up and cool down, whereas PCM regulate temperature naturally, meaning you can keep your sleep space phone and subscription-free. ✅ You like a cushioning sleep surface: PCM are usually used in foams, adding pressure relief and cushioning for those with achy joints or side sleepers with a lighter built. GlacioTex is a fabric made of fibers with high thermal conductivity that quickly and effectively pull heat away from your body while you sleep, keeping you and your sleep surface cool through the night. These fibers are also hypoallergenic and waterproof, providing a stain and bug-resistant barrier over your mattress. Some of our favorite best mattresses of the year come with GlacioTex covers. These include the new-and-improved Helix Elite mattress collection and the Brooklyn Bedding CopperFlex Pro Hybrid mattress. GlacioTex has a lot going for it. It's designed to be cool to touch and hypoallergenic while adding pressure relief to mattresses. When woven into mattress covers, GlacioTex provides a cool sleep surface, helping your body temperature drop in line with your circadian rhythm when you get into bed. Thanks to its protective nature and contribution to pressure relief, you'll come across GlacioTex in top-rated mattress protectors and mattress toppers too as it repels allergens and makes your bed softer, providing more cushioning on joints. A commonly reported drawback of GlacioTex mattress covers is the fact they can have a slippery texture causing a fitted sheet to shift or pop off when you sleep on it, which can be irritating through the night disrupting quality sleep. GlacioTex covers don't tend to be removeable. Even though they provide a waterproof, hypoallergenic barrier, they cannot be removed and put through the washing machine. This means they lack points in terms of mattress cleaning practicality. While GlacioTex toppers offer a cooling sensation, they may not be firm enough for all sleeping positions. Some users who prefer a firmer mattress might find them too soft ✅ You're a seriously hot sleeper: GlacioTex continues to absorb heat through the night without a limit, which is better than PCM for significantly hot sleepers who struggle with night sweats. ✅ You suffer with allergies: GlacioTex covers add an allergen-repellent protective layer to your mattress which is particularly useful if you find yourself sneezing and coughing through the night. ✅ You bedshare with little ones: GlacioTex covers offer waterproof protection and spills and stains. Both PCM and GlacioTex are effective at wicking away heat at night. However, each has its own strengths. GlacioTex is arguably more effective for super hot sleepers as there is no limit to how much heat it can draw away from the body. Meanwhile, PCM is better suited to those whose temperature fluctuates as it can absorb heat, hold it and release it back to the body once cooled down. This helps you maintain a good temperature for sleeping which experts say lies between 65 to 70 F (18 to 21 °C). Either way, PCM and GlacioTex can't do all the heat balancing alone. You'll want to make sure they are paired with other cooling technologies and breathable, moisture-wicking materials like wool, individually-wrapped coils and copper-infused foam to help you sleep comfortably.
