Best Side Sleeper Mattress 2025: Picked By a Sleep Science Coach

If you are looking for the best side-sleeper mattresses, welcome. You’re in good company, as many of the WIRED Reviews team are also side sleepers. So are most Americans. The numbers vary across studies and depend on how rigidly you define “side sleeper,” but between half and three-quarters of people sleep on their side for at least part of the night. If you're a side sleeper, you know how crucial it is that your bed keeps your back aligned while the hips and shoulders get some cushioning. Othe

Data Brokers Are Hiding Their Opt-Out Pages From Google Search

Data brokers are required by California law to provide ways for consumers to request their data be deleted. But good luck finding them. More than 30 of the companies, which collect and sell consumers’ personal information, hid their deletion instructions from Google, according to a review by The Markup and CalMatters of hundreds of broker websites. This creates one more obstacle for consumers who want to delete their data. This story is copublished with The Markup and CalMatters. Many of the

Matter enhancements enable cheaper HomeKit devices and slicker control

The Matter standard – which brings HomeKit compatibility to a far broader range of devices – is getting a significant upgrade. The latest version will enable the production of lower cost HomeKit-compatible smart home devices, as well as slicker control over your existing ones … A quick recap on Matter and HomeKit Originally, brands wanting to offer HomeKit compatibility had to comply with an Apple-specific standard, and submit their devices for approval.

Inside the automated warehouse where robots are packing your groceries

It’s the lack of noise you notice first. There’s no clatter of equipment, rumble of engines, or chatter of coworkers. Only the low hum of electronics. For an industrial space, this is eerily quiet, but it makes sense in a building where robots might outnumber people. I’m at a warehouse — or customer fulfilment center (CFC) — operated by online grocery company Ocado in Luton, just outside London. You might not have heard of Ocado, but it may still have delivered your groceries. Its technology ha

9 Best WIRED-Tested Cooling Mattresses (2025)

BedJet BedJet Other Cooling Options There are a ton of mattresses and related on the market that claim to have cooling benefits. Here are a few others we tested and liked, but not as much as the options above. BedJet 3 for $387: WIRED reviewer Christopher Null liked this climate-control device a lot because it allowed him to sleep cool without having to buy a whole new mattress. This device uses a large blower under your bed to blast hot or cool air beneath your covers. If you like your exist

The Saatva Contour5 for $2,599: The Contour5 is a new offering from Saatva, replacing the popular Loom & Leaf in the company's lineup. Like other Saatva mattresses, but unlike most others on this list, it is not roll-packed and comes delivered on a moving truck.

How to Clean Your Mattress (2025)

It’s important to know how to clean your mattress. Not just for day-to-day cleanliness and hygiene, but let’s say you’re dealing with an emergency—a “my mattress is ruined" situation where you have the frantic energy of an emergency clean-up crew. Is a trip to the dump inevitable? Not necessarily. Before you think, “I’m so clean, this would never happen to me!” I’m telling you, it can. I've seen a lot over the course of my career as a professional mattress tester and certified sleep coach. If y

HomeKit Weekly: Tracking local weather in HomeKit is simple with the Eve Weather

Local weather is one of the most underrated variables in Homekit automation. Over the past few years, I’ve used sensors for everything from knowing when to drip faucets in freezing weather to adjusting the sprinkler schedule with the Eve Aqua on hot days. The Eve Weather has been part of my setup for a while now, and with its 2024 Matter upgrade from last summer, it’s now even more useful across more platforms.

Wolf Memory Foam Hybrid Premium Firm Mattress Review: A New Alpha

Not too unlike wolves moving in a pack, the WIRED Reviews team often bands together to help one another out with product reviews. I’ve tested hundreds of beds and brands over the years, so I get pretty jazzed when something I haven't tried is on the prowl, but I'm a singular tester with only so many nighttime hours a week. Thankfully, my teammate Molly Higgins stepped in to test Wolf's 12-Inch Memory Foam Hybrid Essential Medium-Firm Mattress. Not to spoil anything, but it made our list of the b

Physicists Create First-Ever Antimatter Qubit, Making the Quantum World Even Weirder

Readers following our existential physics coverage may remember a recent breakthrough from CERN concerning matter’s evil twin, antimatter. An outstanding mystery in physics is that our universe contains more matter than antimatter, contradicting most theoretical predictions. Scientists, therefore, understandably want to explain why and how this is the case. CERN announced yet another significant leap for studying antimatter—and this time, the achievement creeps into the realm of quantum computi

Paul Giamatti Is Playing an Alien Bad Guy In ‘Starfleet Academy’

Ahead of Star Trek‘s usual blockbuster panel inside Hall H at San Diego Comic-Con, Entertainment Weekly has lifted the lid on the next new Trek show, Starfleet Academy—and with it, our first look at Paul Giamatti’s mysterious villain. In an extensive preview, Entertainment Weekly revealed a few more intriguing details about the show, which has largely remained hidden ahead of this weekend’s blowout appearance at Comic-Con. Set in the 32nd century after the events of Star Trek: Discovery—and at

Fiberglass-Free, Chemical-Free: Natural Fire Barriers for Mattresses

What do mattresses and a box of matches have in common? It's not just that they’re both rectangular—both can can be very flammable if you're not careful. Mattresses have historically posed a significant fire hazard, and they still can without careful attention to the materials used. In the US, an estimated 20,800 residential fires occurred due to mattresses and bedding igniting from flame exposure between 1996 and 1998, according to FEMA. At that time, fires involving mattresses and bedding wer

Best King-Size Mattresses for 2025, Tested by CNET’s Sleep Experts

Our sleep experts have been testing mattresses, bedding and accessories for years (a few have been testing for up to eight years).

CERN Physicists Find Key Piece of the Matter-Antimatter Puzzle

All matter in our universe has an evil twin: antimatter. Cosmological models suggest that the Big Bang should have created equal amounts of matter and antimatter that cancel each other out. But for reasons physicists still aren’t completely sure about, that didn’t happen. As a result, our universe today hosts slightly more matter than antimatter—our very existence being clear, physical proof. Now, we might be one step closer to explaining why there’s an imbalance between matter and antimatter,

There could be “dark main sequence” stars at the galactic center

For a star, its initial mass is everything. It determines how quickly it burns through its hydrogen and how it will evolve once it starts fusing heavier elements. It's so well understood that scientists have devised a "main sequence" that acts a bit like a periodic table for stars, correlating their mass and age with their properties. The main sequence, however, is based on an assumption that's almost always true: All of the energy involved comes from the gravity-driven fusion of lighter elemen

Which King Mattress Size Rules Your Sleep Style? (2025)

King-sized mattresses are the largest mattress size you can get, right? Surprise! It’s not just the standard king anymore. With king mattress size options these days, you’ve got territories, states, and split surfaces all involved. If you weren’t prepared for this pop quiz in mattress geography, worry not—I am.

Do You Need a Box Spring for Your Modern-Day Mattress? (2025)

You're probably familiar with a box spring, the simple wood frame with springs that acts as a support base under older mattresses. It's not a highly technical piece of equipment like a smart bed (or a trampoline, wouldn't that be fun)—this kind of mattress foundation has persisted through the ages solely due to its simple and durable design. But have you noticed you may not be seeing them as often nowadays? In my opinion as a career mattress tester, contemporary mattresses are on their way to m

Dozens of ‘Ghost Galaxies’ Are Orbiting the Milky Way, Astronomers Suspect

The Lambda Cold Dark Matter (LCDM) theory suggests that most galaxies are low-mass dwarf galaxies, many of which orbit larger galaxies like the Milky Way. More broadly, the LCDM represents our best understanding of how the universe works. But there’s a problem. According to the theory, the Milky Way should have significantly more satellite galaxies than scientists have observed with telescopes and predicted with computer simulations. By combining the highest-resolution supercomputer simulations
