A Behind-the-Scenes Look Inside a Mattress Factory

stearns & foster mattress factory tour
I got the Golden Ticket!

Well … sort of. Full disclosure, Stearns & Foster approached The Manual with an invitation for a writer to visit the company’s Greensboro, North Carolina, headquarters to not only get a behind the scenes look at a mattress factory, but also to “make [our] own mattress.” My editor tossed the story my way, where he received a resounding “huh?” from me.

Don’t get me wrong. I’m a self-professed design geek, and an issue of Dwell is like soft porn for me, but mattresses? I mean, aside from the obvious, where’s the sex? A mattress is a mattress, right? Boy, was I wrong.

Once Upon a Mattress

At Stearns & Foster’s immaculately decorated headquarters, we were ushered into the company’s product showroom where studio lighting illuminated three beds. Five writers and editors suddenly had performance anxiety, but before long we were contorting ourselves into positions to recreate how we sleep all while the Stearns & Foster product development and marketing teams and a photographer and his assistant looked on. We were encouraged to roll around on the three beds of varying degrees of firmness to find the most comfortable according to our own preference. Oddly enough, we all ended up choosing the same model. It must say something about how writers keep themselves up at night worrying about their stories.

Then there was a quick lesson about springs and pillow tops: Stearns & Foster has a patented “IntelliCoil” inner construction that keeps things … ahem … bouncy, and a collection of other techniques that not only add comfort but also prevent parts of the mattress from sagging over time. Of course the pillow-top (that extra, padded layer on top of many modern mattresses) itself is a masterpiece of modern engineering, and as it grew thicker and softer, we found ourselves getting more comfortable, to the point that we were definitely in need of an espresso.

We Are the Robots

To wake us up, we moved from the showroom to the real guts of the facility, including a testing laboratory where the products are subject to all sorts of indignities. Mattresses are massaged more than 100,000 times by a 240 pound Rollator, punched in the gut over and over again with a 230 pound weight, and repeatedly sat upon by a robot named NOBI (short for “no body impressions”) with a big, wooden butt meant to simulate somebody getting in and out of bed for ten years (that’s 5,000 times, spread across four days, and S&F is the only company that utilizes this technology, by the way).

We were then introduced to a part of the research and development team that uses sophisticated machinery to bend and twist steel wire into convoluted shapes — think 3D printing meets (a very intelligent) pair of pliers. This machine (which we weren’t even allowed to photograph) is used to develop new coil technology and the Stearns & Foster team has even won awards for their engineering proficiency. An adjoining lab subjects fibers and fabrics through tests to assure durability, as well as temperature and humidity resistance.

Burn After Reading

A quick walk across the parking lot and things got really exciting when we went to the Fire Resistance Lab and got to watch some guys set shit on fire.

No, really. This is where mattresses are randomly tested to be sure they are up to Consumer Product Safety Commission standards for fire retardancy. Stearns & Foster’s parent company, Tempur Sealy International, is the only bedding manufacturer to have such a lab on site.

It was at just about this point in the day when I realized I was surrounded by chemical, mechanical, and various other types of engineers, and really started to geek out. As I said, we’re talking mattresses here, but there are almost as much technology and experience going into production as an automobile. We headed onto the actual factory floor where monitors tracked productivity throughout the assembly process. Sensors checked movement to keep traffic flowing smoothly and safely, and even watched trucks to make sure they were locked into place on the loading dock and that no employees accidentally get shipped off! This plant ships 8,000 mattresses a week…and it’s one of the company’s smaller facilities.

A few steps further and we headed into the Prototype Lab, where Master Craftsman, promoted from the ranks of the factory floor for their proficiency and expertise, bustle about like Santa’s elves the week before Christmas. The marketing and product development team have the very latest in technology at their disposal, which is sometimes as simple as a sewing machine but can also involve some pretty heavy duty quilting equipment. Experimenting with various hand-crafting and machined techniques, the team can crank out mattress prototypes, with the benefit of hundreds of years of combined experience to ensure maximum results. Here we each got to try our hand at stitching, tufting, gluing, etc., and really gained an appreciation for the labor and skill that go into creating a modern mattress. It was easy to understand why each one gets a hand-signed label from the craftsman who built the bed.

Sleep Writing

A few weeks later my mattress, from the Lux Estate Collection, was delivered to my home. I can only tell you that since then, I have been sleeping like a baby most nights. One Saturday morning, having gone to bed a little early and with no alarm going off, I was so deeply asleep, the only thing I could compare it to was going under anesthesia.


The lesson learned here is not only that a new mattress can be life-changing, but that with modern technology, going to bed commands a whole new level of respect. It’s recommended to change your mattress every ten years, so head in for an upgrade if it’s been a decade or so. I would definitely recommend going to a store and rolling around a bit to be sure that you find the right “fit,” but by all means, buy the best you can afford. Your “Zzzs” will thank you.

If a regular mattress and bed aren’t good enough for you though, if you really need something more, this Chinese super-bed may just be what you’re looking for.

The Night Agent season 2: Everything we know so far
We'll get you ready for The Night Agent season 2!
Luciane Buchanan and Gabriel Basso in The Night Agent.

The Night Agent may not be everyone's choice to be among the best shows on Netflix, but it's in the top ten for us! The Shield creator Shawn Ryan adapted Matthew Quirk's spy action thriller, The Night Agent, for Netflix in 2023, and it proved to be a hit out of the gate. By Netflix's internal metrics, it's the sixth-highest viewed series in the history of the platform.

Those kind of numbers mean that a second season was inevitable, and Netflix made it official just over a week after The Night Agent premiered. Since the series is back in production, the details about what's coming up on the show have started to trickle out. To help you stay on top of this series, here's everything we know about The Night Agent season 2.

The 10 best Dominican cigars I’ve tried and tested in 2024
Santo Domingo in the Dominican Republic.

Every seasoned cigar lover has a preference for where their cigars come from. Cuban and Cuban cigars are the more obvious choices, but there is also Nicaraguan tobacco, Central African, Indonesian, Mexican, Ecuadorian, and Dominican. Some tobacco is even grown in the United States. Each region has a distinct flavor profile that adds a little something extra to the tobacco grown locally, as well as the cigars made there. The Dominican Republic is prized by many connoisseurs because of exactly this -- a rich, unique profile that enhances Dominican-grown cigars. That's in no small part due to the fertile soil and thriving climate of the region, which is ideal for tobacco growth and cultivation. If you've never tried a Dominican cigar, you're in for a real treat, there are some fantastic options out there.
The best Dominican cigars I've tried

Out of all the cigar guides I've put together so far, this one was one of the more interesting experiences for me. I had a great time trying out Dominican cigars, and I've definitely come away with an appreciation for blends made in the region. I'd also like to point out that Corey Suarez helped recommend some of these. If you haven't tried the JR Cigars or Cigars.com concierge service yet, you really should. Here's a little more about all of the best Dominican cigars I've tried:

The 12 best Connecticut cigars I’ve tried and tested in 2024
Best Connecticut cigars up close and personal

Connecticut cigars are the clear winner for smoking on a hot summer day, in the morning with some coffee, or when you just don't want a swift kick in the teeth (of pepper). There's no shortage of options, either. Connecticut shade wrappers are one of the most prevalent in the world of cigars, and it's certainly the most common natural shade. Maduro is also popular, but the two wrapper types couldn't be any more different. Connecticut wrappers, and by proxy Connecticut cigars, are typically mild to medium in strength and brimming with creamy, smooth flavors. They're composed of tobacco leaves grown in the Connecticut River Valley in the United States -- which is where the name Connecticut comes from. Consistent and flavorful, some of the best beginner-friendly cigars are Connecticut-wrapped, but you should never sell them short. A Connecticut shade cigar can be just as refined, elegant, and premium as any other. If you know where to look, you may even find some of your favorite blends in the category across a wide range of brands and cigar makers.

I'm about to take you on a magical, doughy, and delicious trek through the broad range of Connecticut cigars. In short, here are the best Connecticut cigars tried and tested by a genuine enthusiast of the craft: yours truly.
The best Connecticut cigars I've tried and tested
While the Connecticut Broadleaf wrapper is considered a Connecticut shade, I did my best to steer clear of recommending them for this list. They're better classified as a Maduro shade or darker cigar. That doesn't mean you should avoid them, quite the contrary. But for this list, I wanted to stick to smooth, relaxing smokes that are strong on flavor but not quite so strong on pepper and spice. I also tried not to choose a lot of repeats. If you see your favorite cigar missing, that might be because it was recommended on another list or it just didn't make the cut. If you have any recommendations of your own, I'm always available through social media or email. Without further ado, let's get this thing started.
