For a decade I sat on whatever chair came with my office, or whatever cheap-but-Wirecutter-approved chair I'd gotten on Black Friday. The chairs were never quite right. My back wasn't great by the end of long workdays, but I'd attributed that to the workday rather than the chair.
A year ago I bought a refurbished Herman Miller Aeron for $720 and it's the single best money I've spent on my desk setup. Including the desk.
Why I waited so long
Pricing. A new Aeron is $1,800 to $2,200 depending on configuration. That's a real number. Even adjusted for "this thing will last twelve years" — and Aerons demonstrably do — it's hard to spend that on something I'd be sitting on rather than typing on. So for years I bought $300 chairs and assumed they'd be enough.
They were not. The chairs would feel fine for the first few months and then I'd start noticing back pain by 5pm, then 4pm, then by lunch. I'd replace the chair, the cycle would repeat. Lifetime cost on cheap chairs over a decade was probably $2,500 in chairs and an immeasurable amount in afternoon discomfort.
The refurb market
Here's the thing I didn't know when I was buying $300 chairs: the refurbished Aeron market is enormous. Companies buy out office liquidation, restore the chairs to factory-spec condition, replace worn parts (the mesh, the foam, the armrest pads), and sell them with warranties. A solid refurb runs $600-$900 depending on configuration and reseller. That's still real money, but it's a third of new and three times less than I'd assumed.
The chair I bought is a Size B (medium) Aeron Remastered (the post-2017 redesign with the new mesh and re-engineered tilt). It came with adjustable lumbar, adjustable arms, and a tilt limiter. The reseller — Crandall Office Furniture in Michigan — replaced the seat pan, the back mesh, and the armrest tops, and gave me a 12-year warranty on the parts they touched. The chair arrived looking new and has held up perfectly through a year of daily eight-to-ten-hour use.
What it actually fixed
Lower back pain in the afternoon. Gone within two weeks. This was the headline benefit and it has stayed gone.
The drift. With cheaper chairs I'd notice myself slumping forward as the day went on, and I'd have to consciously correct posture. The Aeron's structure makes that correction unnecessary — the chair holds the position my back wants to be in, by default. I'm doing less work to sit correctly, which means I sit correctly for more of the day.
The tilt mechanism. The Aeron's tilt isn't just "lean back" — it's a counterweighted forward-and-back that adjusts based on where your weight is. I find myself shifting positions naturally throughout the day in a way I never did on locked-tilt chairs. That movement is a real ergonomic benefit; static seating is one of the worst things you can do to your spine over years.
The non-Aeron alternatives I considered
I'd looked at a lot of options before settling on the Aeron. The honest comparison:
Steelcase Leap. The Aeron's most direct competitor, often preferred by people with thoracic-spine issues. I sat in one for two days at a coworking space and liked it; it's at least as comfortable as the Aeron, possibly more so for some body types. Refurbs are similarly priced. If you can sit in both and pick, it's a personal preference call.
Herman Miller Embody. More expensive than the Aeron new, more expensive refurbished. I tried one and didn't love it as much as expected — it's incredible for relaxed sitting but I prefer the Aeron's structure for keyboard work. Probably ideal for people who do more reading than typing.
Various $400-$600 "Aeron-likes." The Branch Ergonomic Chair, the Autonomous Ergochair, that kind of thing. I sat in two and they were notably worse than the Aeron — the lumbar wasn't as well-engineered, the tilt felt cheaper, the mesh deformed in ways the Aeron's didn't. They're better than $200 chairs, but the gap to a refurbished Aeron is real.
Ikea Markus. I had one before this. It's a solid budget chair. It is not a chair you should be sitting in eight hours a day for years if you can avoid it.
What to know about buying refurbished
Buy from a real reseller, not a random eBay listing. The good resellers — Crandall, Office Designs, Madison Seating, a few regional ones — disclose what they restored, what's original, and what warranty they offer. Random eBay Aerons are often missing the lumbar, have damaged mesh, or are mismatched parts cobbled together to look complete.
Get the size right. The Aeron comes in three sizes (A, B, C) and they're not interchangeable. Size B fits most people 5'4" to 6'1". Size A is for smaller frames; Size C for larger. Sit in one, or measure carefully against the chart, before buying.
Configuration matters. You want adjustable arms (the older "fixed arms" version is much less useful), adjustable lumbar (not the older "PostureFit" pad), and ideally a tilt limiter. The fully-loaded refurb is what you want.
Don't pay new prices for the warranty. Herman Miller's 12-year warranty on new chairs is good, but most refurb resellers offer 10-12 years on the components they refurbish. The marginal value of a manufacturer warranty over a quality reseller warranty isn't worth the $1,000+ price difference.
One year later
I notice the chair when something's wrong with my desk setup, and otherwise don't think about it. That's the benchmark for good ergonomics — the equipment disappears, your attention stays on the work. Combined with the rest of my desk setup, I'm more comfortable working from home than I've ever been at any office.
I've recommended the refurb-Aeron path to maybe ten people in the past year. Two bought one. Both reported back the same way: "Why did I wait so long." That's the right reaction. A great chair sounds like a luxury until you're sitting in it. Then it sounds like a tool, and you wonder why you ever tried to do the job without one.
