Best Dog Beds (2025): For All Kinds of Dogs in All Kinds of Spaces

You know what gets me jazzed? Dogs. And some of the best dog beds, funny enough, often come from human-mattress brands that you may recognize. Now, if we were to consult the dogs themselves, I'm sure that they would be more than happy to tag along with you in your bed, on the couch, or any bed provided to them. As a professional mattress tester and certified sleep science coach, however, I can tell you that you may not be getting your best sleep when you let your dog sleep on your bed with you.

The Best Hybrid Mattresses for Couples, Back Pain, and More (2025)

the best hybrid mattress is sort of like cake. There are always going to be a few key ingredients—in the case of a mattress, that's springs and foam. Those two elements are layered up and combined with an almost endless assortment of other ingredients (latex, coils, foam layers of various densities, assorted fabrics). The art is in the details of the recipe, and mattress brands are carefully combining each ingredient in a specific ratio to create a comfortable bed. Hybrid mattresses are what we

Hong Kong Disneyland Teases Avengers and Pixar Attractions

Disneyland Hong Kong first opened 20 years ago, and to celebrate, the company showed off concept for what’s coming in the future. Concept art below shows teases for attractions based on Marvel and Pixar. For the superheroes, one art features the Avengers headquarters, while another shows Spider-Man with Doctor Strange, Black Panther, and Thor in Asgard around a pod of parkgoers dropping through the Bifrost Bridge. This concept art—and a previously released art of Spidey holding a pod while figh

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 I have seen some severe cases of people using wildly outdated or damaged mattresses (think 20 years or more, or covered in duct tape), and pillows so shredded into tatters that it makes you wonder how they even resembled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

DreamCloud Hybrid Mattress Review: Support and Value

I’ve written numerous reviews of the DreamCloud Classic Hybrid mattress over the past six years of my mattress testing career. It was on my short list of favorites then, and its newest iteration, released in May, still is. This is no small feat, especially given the current supply-chain issues, tariffs, and price increases, all of which can affect the materials (and thus, the performance) of a mattress. Plus, I’m like the Simon Cowell of mattress world—a bed has to work really hard to impress me

30% Off Tempur-Pedic Promo Codes | September 2025

For those that also want to avoid putting a strain on their budget, now’s a good time to look, as there are several limited-time deals currently running

Puffy Cloud Mattress Review: Soft but Supportive

I will admit that, once upon a time, I was not the Puffy Cloud’s biggest supporter. I’ve tested this memory foam mattress multiple times over my five-year mattress testing career and believed it simply wasn’t for me—too soft, not enough spinal support. Well, times change, don’t they? Granted, during my previous tests, I didn’t spend a whole week sleeping on the Cloud in my own bedroom, as I did this time. I now also consider myself a side sleeper, which has a whole other set of requirements than

Honest Review of the New Tiami Mattress (2025)

It’s always an exciting day when I get to try out a new mattress brand. Tiami comes from the founder of Leesa, bringing some serious credentials—Leesa’s Sapira Chill is our favorite hybrid mattress. Will Tiami be able to live up to its famous sibling? I’m a certified sleep science coach with more than five and a half years of mattress testing experience, and here are my thoughts after a week of sleeping on this bed. What Makes Tiami Tick Photograph: Julia Forbes Tiami’s raison d'être is its s

Best Innerspring Mattress in 2025

All online brands offer a free trial, free shipping and a warranty, but some brands are more generous with their policies than others. Motion isolation, edge support and temperature are important features for couples or people who sleep hot to consider. Hot sleepers should consider a mattress that boasts special cooling features. Couples want minimal motion transfer and a strong, supportive bed perimeter. Hybrid mattresses tend to be best for people who want extra support and durability. Sleep

The attr() function in CSS now supports types

The attr() function in CSS is a powerful function that allows you to use the value of an attribute of an HTML element as the value of a CSS property. This function is commonly used with the content property in pseudo-elements to display the value of an attribute on the page. The attr() function has been around for a while and is widely used in CSS. However, it was limited to only accepting a single argument: the name of the attribute whose value you wanted to use. On top of that, the value ret

Why is D3 so Verbose?

Why is D3 Code So Long and Complicated (or Why is it So Verbose)? D3 is a b***h of a language at first glance. It’s long. It’s complicated and verbose. You have to enter what feels like an obscene amount of key strokes to draw one line. I’m currently about one-third of the way through my journey of learning D3.js, having finished Interactive Visualisation for the Web by Scott Murray, and now picking my way through D3.js in Action by Elijah Meeks and Anne-Marie Dufour.

Yes, You Really Need a Bed Frame for Your Mattress and Here’s Why

I'm no stranger to cutting costs when it's time to buy furniture. But, when a recent CNET survey found out that roughly six in 10 US adults are willing to invest in their bed setup, as a sleep expert, I knew what I had to recommend: buy a bed frame. Now, if you're wondering why? There are many reasons why a bed frame is a key part of your bedding setup. A bed frame's purpose is to protect you and your mattress from the downsides of sleeping on the floor. Not only that, but mattresses are expens

Best Organic Mattresses (2025): Birch, Avocado, Naturepedic, More

After years of testing, the Avocado Green hybrid mattress remains one of the best organic mattresses I've slept on. It's the only mattress my wife and I can agree on. She likes a soft mattress, and I prefer a firm one. This model somehow manages to be both without being too much of either. It's also good for combination sleepers like myself, who spend time in just about every position in the course of a night. After nearly three years of sleeping on this Avocado, it's proven its durability—there

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.

Virtual 6NF

One of the goals of this substack is to research ways of removing historical cruft from the way relational model is taught. One thing that puzzles me particularly is why Sixth Normal Form (6NF) is historically treated so... reverently? Lots of texts on the internet consider 6NF to be “exotic”, “academic”, “never used in practice”, etc., etc. As software developers, we can solve any problem by adding one level of abstraction, and database modeling is not an exception.

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.

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
