How Often Should You Replace Your Mattress and Bedding?

As foreboding as it sounds, nothing lasts forever—not even your mattress, sheets, and pillows. It’s essential to know how often to replace your mattress and bedding, not just for hygiene reasons, but for ensuring you’re getting optimal support and comfort to aid in sleep. I have seen some severe cases of people using wildly outdated or damaged mattresses (think 20 years or more, or covered in duct tape), and pillows so shredded into tatters that it makes you wonder how they even resembled pillow

The Best Cooling Sheets (2025): Brooklinen, Slumber Cloud, Buffy

There's a lot of terminology thrown around in the world of cooling sheets and cooling mattresses. Temperature regulating! Airflow! Moisture wicking! Phase-change material! Most of the time, these features come back to how breathable the sheets are. Breathability means moisture can better evaporate, and “temperature-regulating” usually means the sheets are breathable enough to release the heat and moisture from your body. What makes sheets breathable? Cotton, flax linen, and bamboo have great br

I'm a Hot Sleeper, and This $0 Cooling Trick Has Curbed My Night Sweats

I'm a hot sleeper to the point where even a steady stream of air conditioning can't save me from night sweats. So over the years, I've done everything I can think of to stay cool while sleeping — switched my comforter to a light quilt, my cotton pillowcase to a silk one, my pajamas to breathable fabrics like linen — but funny enough, the most helpful change I made cost me nothing and it was right in my linen closet. On my most recent vacation, I stayed at a hotel where the comforter was so thic

Ratfactor's Illustrated Guide to Folding Fitted Sheets

If you search the Web for the history of fitted sheets, you’re going to find a reference to exactly two patents: 1959 - Bertha Berman of New York: FITTED BED SHEET CONSTRUCTION (PDF, 355Kb) 1992 - Gisele Jubinville of Alberta: MATTRESS COVER/FITTED BED SHEET (PDF, 492Kb) Now, if you actually look at the patents, what you’ll see is that Berman’s was a more complex design that consisted of multiple pieces (but does feature elastic!) And Jubinville’s design, indeed, has the stitched-in elastic d

Liquid Glass on an iMac G4 may be the cutest thing you see today

I’ve always thought that the iMac G4 was one of the most beautiful products Apple has ever made. It’s now more than two decades old, but I still think it looks as futuristic as it did on the day it launched. I’d also say that Apple’s 2025 Mac operating system looks somehow just right on this 2002 machine, as ably achieved by self-described tinkerer Colby Sheets … Sheets described his creation of the iMac G4 with an M1 chip as a passion project in celebration of the life and inspiration of Stev

Scientists Alarmed as Floodwater Punches Through Greenland's Ice Sheet

Scientists were caught by surprise after discovering a massive flood of subglacial lakewater burst through Greenland's ice sheet, spilling copious amounts of water across its surface. As detailed in a new paper published in the journal Nature Geoscience, it's the first time such a phenomenon has been observed, highlighting the fierce power being stored in meltwater lurking beneath a thick sheet of ice. The event also defies our predictions of how the Greenland ice sheet evolves over time, even

Zenbivy Light Bed Review: Still the Best Backcountry Sleep System

Zenbivy, renowned makers of outdoor bedding, have a clever quilt-and-sheet backcountry sleep system that gave me the best sleep I’ve ever had on the trail. The only problem with the original version was the weight, which was more than I generally like to carry on longer trips. Zenbivy has an ultralight version of its bed, but the fabrics aren't nearly as nice and soft as the original. This year Zenbivy updated its Light Bed, which sits between the ultralight and the regular (both of which were

Bedsure's Bamboo Cooling Sheets Are Silky Soft, Durable, and Cheap

I’ve met many supposedly “cooling” sheets in my time as a mattress and bedding tester, and I have been disappointed more often than not. A cooling mattress can’t do all the heavy lifting with temperature regulation, and I’ll forever emphasize that your choice of bedding matters just as much—which is why I'm an unapologetic sheet snob. Which brings me to Bedsure, a brand I stumbled across on Amazon in a last-ditch effort to find some decent sheets when mine bit the dust (rather, my dogs bit holes

13 Best Prime Day Mattress Deals Plus Top Bedding Sales (2025)

As you may have noticed, mattress shopping holidays aren't limited to just Memorial Day, Labor Day, or even the Fourth of July anymore. Now that Amazon Prime Day is nearly a week long, it's become something of a holiday in and of itself, so it makes sense that mattresses (plus other bedding!) will be on sale too, both on Amazon and beyond. We've listed our favorite Prime Day mattress deals that someone on our staff has tested themselves and personally vouched for. If you want to know more about

Operators, Not Users and Programmers

This post is part 0 of a multi-part series called “the computer of the next 200 years”. the modern distinction between “programmers” and “users” is evil and destroys agency. consider how the spreadsheets grow🔗 spreadsheets are hugely successful. Felienne Hermans, who has spent her career studying spreadsheets, attributes this success to "their immediate feedback system and their continuous deployment model": the spreadsheet shows you its result as soon as you open it, and it requires no steps

Songscription launches an AI-powered ‘Shazam for sheet music’

A small company called Songscription launched last week with AI models that automate music transcription, turning an audio file of a song into sheet music within minutes. Operating on a freemium model, the product is geared toward both professional and hobbyist musicians. “We hope to make playing music more enjoyable,” Andrew Carlins, CEO of Songscription and a student in Stanford’s MBA/MA in Education program, told TechCrunch. “We imagine a future where a rural Nebraska high school band teache

Google Maps makes starting a collaborative list less confusing

Aamir Siddiqui / Android Authority TL;DR Google Maps is rolling out a tweaked sharing menu for places. When a place is selected, tapping on the Share chip will bring up a new Share sheet with options for: Share this place, Copy link, and Share as a collaborative list. In 2023, Google Maps introduced a feature to allow users to create collaborative lists with friends and family, consisting of places everyone wanted to visit. The process was as simple as selecting a place, tapping share, and fi

6 Best Organic Sheets (2025), Tested and Reviewed

What to Look for in Organic Sheets Organic means many things. It's often used to confirm that food was grown without toxic pesticides and chemicals, and doesn't have things like growth hormones or GMOs, in order to label it as organic food. For bedding, it should mean both that organic materials were used to make the fabric—no toxic pesticides used in farming, etc.—and that they were produced organically with nontoxic chemicals. You'll want at least two certifications to prove this. Most sheet

Sharing to group chats in Google Messages could soon get much easier (APK teardown)

Edgar Cervantes / Android Authority TL;DR The latest Google Messages beta has revealed that Google is working on integrating group chats with the Android share sheet. This will allow users to share content to group chats directly from other apps, saving them a few clicks. Thanks to the recent RCS push from iPhone users, we’re seeing group chats return for Android users where they don’t feel as alienated as before. Google Messages has a pretty decent group chat feature, but there’s definitely
