Best Air Mattresses of 2025, Tested by CNET Experts

There are a few general things to consider when shopping for the best air mattress. Price Price is the primary criterion for most people searching for the best air mattress. A queen-size bed can cost as little as $30, while the most expensive air mattresses can cost hundreds of dollars. A higher price doesn't always mean a taller air bed, a better air mattress, better air pressure, a self-inflating mattress, a better sleeping surface, more comfort or a decent night's sleep. Inflation The bes

What Type of Mattress Is Right for You? (2025)

If you're looking to buy a mattress, I don't need to tell you the research process is complex.

My hope is that by the time you finish reading this, you’ll have a better idea of what kind of mattress you’re looking for, which will make your final decision that much easier.

Deliberate sabotage is rare, and incidents resulting from a mistaken search for copper should be even rarer.

The Morning After: Trump Mobile is a thing

Oh, Gold. It’s not April 1, it’s just a weird surprise. Donald Trump is launching a phone called Trump Mobile, which comes with wireless plans (starting at $47.25) and even a phone called the T1 Phone. During the announcement event at Trump Tower in New York City, Donald Trump Jr. said they were building something for “people who have been underserved,” and to “make sure that real Americans could get true value from their mobile carriers.” (Trump Mobile’s only plan is roughly double that of eq

Did Samsung's fitness coach just outpace Apple's Workout Buddy?

Health wearables are leaning into AI-powered health coaches and advisors, which can use all the health and fitness data they aggregate to deliver actionable insights or help the user achieve a fitness goal. Last week, Apple debuted a new AI-powered WatchOS 26 feature that will be available on Apple Watches in the coming months. Workout Buddy is the smartwatch's health coach, guiding wearers through a workout and providing historical stats, encouragement, and more. Also: Your Galaxy Watch is ge

Want to ditch Windows? This Linux distro makes that transition easy

Jack Wallen / Elyse Betters Picaro / ZDNET Over the past year, several Windows-like Linux distributions have been given the spotlight. A couple of those distributions were nothing more than malware in disguise, which has made me a bit squirrely about trying others, but to let a couple of bad apples spoil the entire bushel isn't fair, in my opinion. So when I came across yet another, I decided to give it a try. That distribution is AnduinOS, which is a custom Ubuntu-based Linux distribution to

AMD's Pre-Zen Interconnect: Testing Trinity's Northbridge

Today, AMD’s Infinity Fabric interconnect is ubiquitous across the company’s lineup. Infinity Fabric provides well-defined interfaces to a transport layer, and lets different functional blocks treat the interconnect as a black box. The system worked well enough to let AMD create integrated GPU products all the way from the Steam Deck’s tiny van Gogh APU, to giant systems packing four MI300A chips. Across all those offerings, Infinity Fabric enables coherent memory access as CPU and GPU requests

FBC: Firebreak: 6 Fun Nods to Control

FBC: Firebreak is studio Remedy Entertainment's first multiplayer romp. As a Left 4 Dead-esque objective-based horde shooter taking place in the Oldest House (the headquarters for the Federal Bureau of Control), the game is heavy on action and light on story. That doesn't mean that the game is completely divorced from the shared Remedyverse that bridges the events of Control and the Alan Wake series. Firebreak takes place six years after the events of Control, and dimension-hopping Hiss invader

The GameSir Cyclone 2 Has One Thing That Keeps It From Being a Great Nintendo Switch Controller

GameSir has made a name for itself over the past few years by building solid gaming controllers with top-notch features, often at lower prices than the competition. One of its latest controllers, the Cyclone 2, offers a lot of great things including support for multiple platforms, several connectivity options and solid triggers and joysticks. But the lackluster buttons and janky software make it hard to recommend when there are dozens of other great controllers for around the same price. What I

Finland warms up the world's largest sand battery, the economics look appealing

It doesn’t look like much, but Finland recently flipped the switch on the world’s largest sand-based battery. Yes, sand. A sand battery is a type of thermal energy storage system that uses sand or crushed rock to store heat. Electricity — typically from renewable sources — is used to heat the sand. That stored heat can later be used for various ends, including to warm buildings. The economics are compelling, and it’s hard to get any cheaper than the crushed soapstone now housed inside an insu

What I talk about when I talk about IRs

I have a lot of thoughts about the design of compiler intermediate representations (IRs). In this post I’m going to try and communicate some of those ideas and why I think they are important. The overarching idea is being able to make decisions with only local information. That comes in a couple of different flavors. We’ll assume that we’re compiling a method at a time, instead of a something more trace-like (tracing, tracelets, basic block versioning, etc). Control-flow graphs A function wi

F1 in Canada: Well, that crash was bound to happen

The Circuit Gilles Villeneuve on the Île Notre-Dame in Montreal has long been home to the Canadian Grand Prix. The artificial island was originally built for Expo 67 but was later remodeled for the 1976 Olympics; a race track was then constructed out of the roads on the island in 1978. F1 has come and gone in the US and Mexico in that time, but Canada has been a near-constant, missing just 2009. Many of those races have been classics. 2007 saw Lewis Hamilton's first win, when he was a rookie wi

Elon Musk Posts "No Kings" Message as Protests Rage Against Trump

Late Sunday night, billionaire Elon Musk was seemingly kept awake by the specter of the "No Kings" mass protests across the United States over the weekend. Millions of people took to the streets to counter a controversial — and apparently boring-as-hell — military parade, sponsored by UFC and put on by president Donald Trump, with the striking choice to hold it on his birthday. Musk took to his own social media platform, posting a screenshot of the iconic horror video game "Bioshock," which sh

NASA Sends Scary Email to Staff

An agency-wide, internal email sent out to all NASA staff warns of major changes ahead. The space agency is expected to majorly change its direction under the Trump administration's control, severing itself from its science-based roots and doubling down on landing humans on Mars, as the president proclaimed during a speech in front of Congress in March. According to the administration's proposed budget for NASA's fiscal year 2026, the agency could soon go through drastic changes of devastating

Best Organic Mattresses (2025): Certified Nontoxic, Natural Sleep
