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 I have seen some severe cases of people using wildly outdated or damaged mattresses (think 20 years or more, or covered in duct tape), and pillows so shredded into tatters that it makes you wonder how they even resembled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

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

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

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
