Your average furniture designer would like you to believe his products will change your life. Most don't, of course, but for millions of desk jockeys in offices around the globe, one task chair has done precisely that: the Aeron by Bill Stumpf (1936–2006) and Don Chadwick for Herman Miller. Originally conceived as a product for the elderly (Stumpf was the son of a gerontology nurse which undoubtedly influenced his approach), the task chair came to symbolize of a shift in the way offices conceived of furniture for employees. Everyone from a secretary to a CEO could have his or her own throne that represented the most thoughtful details and advanced engineering of the time. The design was an instant hit. MoMA acquired one for its collection before it debuted on the market in 1994. The idea of the chair was that it would conform to the sitter's needs, not vice versa. So the seat is made from breathable, stretchable fabric that's suspended like a supportive hammock on an aluminum frame.
There are numerous adjustments—seat height, arm height and angle, tension of the reclining seat back, lumbar support position and depth—to accommodate myriad users. Need to have an impromptu meeting with a coworker? The Aeron is set on wheels to make moving it around a breeze. The Aeron was based on the following tenets, which still inform the design and development of new task chairs for Herman Miller: 1. A chair should be perceived as comfortable before, during, and after sitting upon it. Comfort is as much a matter of the mind as of the body. 2. A chair should enhance the appearance of the person sitting upon it. 3. While allowing postural movement, the chair should also embrace the body. 4. The chair should provide correct support for the sacrum as well as the lumbar region of the spine. 5. The chair should provide a simple means for height and angular adjustments. A chair should be friendly to all parts of the body that touch it. Take Yves Behar's Sayl chair: it's 3-D back—inspired by suspension bridges—performs similarly to Stumpf and Chadwick's design, but eliminates the need for a separate lumbar support thanks to its supportive yet pliable structure.
The Aeron has also inspired knock-offs that seek to imitate its signature design elements, like the mesh construction. But the true testament to the chair's enduring influence could also be measured in pop-culture references. When the Simpsons depicted heaven in a March 2005 episode, God was perched in none other than Stumpf and Chadwick's masterpiece. Of course, the Aeron's legacy isn't all roses. As some keenly point out, the chair came to represent startup era excess. And thanks to its ergonomic design, the chair offered previously unheard of comfort—so much so that it actually encouraged people to remain sedentary for extended periods, not the healthiest of behaviors. Still, you have to give credit to a guy who managed to get people excited about a chair. Today would have been Stumpf's 80th birthday. And while the Aeron is what he'll be remembered for, it wasn't the only design he produced for Herman Miller: the manufacturer has sold over 10 million of his ergonomic chairs—seven million of which are Aerons—through the decades.
We salute his contributions to making offices suck a little less. All Images: courtesy Herman MillerIt is also possible to "upgrade" the standard chair with options including pivoting arms pads, lumbar support pads, adjustable spine support. The chair can also be upgraded to have a polished aluminium base and/or polished aluminium seat and The Aeron chair from Herman Miller is most readily recognised from its "Pellicle" fabric.The wrong chair = real health problems. (Total read time: 8 minutes) In this post I’ll cover how I identified the best high-end chairs in the world, which I ultimately chose, and the tangible results that followed. In January of 2005, I found myself on a veranda in Panama after the usual afternoon rain, dreaming of the upcoming year and reflecting on lessons learned since leaving the US. Maria Elena, the matriarch of the Panamanian family that had adopted me, sipped her iced tea and pointed at my bruised feet: “Tim, let me share some advice I was once given.
Buy the most comfortable bed and pair of shoes you can afford. If you’re not in one, you’ll be in the other.” I followed her advice upon returning to CA and the results were sudden: Plantar Fasciitis disappeared, as did shoulder impingement after switching from coil-spring to foam-layered mattresses. But what about chairs? On January 4th, 2009, I tweeted out the following: “Is the Aeron chair worth it? http://tr.im/2uxd Do you have any fave chairs for extended sitting and writing?” Even though I’m financially comfortable now, I didn’t grow up spending a lot of money, which I’m thankful for. To this day, I’ve never paid for first-class airfare for myself. Not that it isn’t worth it — I just can’t do it. Similarly, I had trouble believing a chair could possibly be worth $850-$1,200, but my back pain led me to pose the question to the omniscient Interweb. More than 95% of Aeron users replied with “yes, absolutely”, but it wasn’t the only chair with a cult-like following.
Four of the five are manufactured by Herman Miller (HM) and Humanscale (HS). Prices are from Amazon, as are the star reviews, but discounts of $200-400 can be negotiated with dealers. Both eBay and Craiglist offer similar discounts. In descending order of popularity: 1. Aeron (Fully loaded) (HM) – $879 (1 review; average review: 5 stars) Used at NASA mission control and tech start-ups worldwide.2. Mirra (fully loaded) (HM) – $829 (14 reviews; average review: 4.5 stars) Note: the Herman Miller sales representatives I spoke with preferred the Mirra seat feel for shorter legs vs. the Aeron. Easier to adjust: Mirra is about 9 revolutions from loosest to tightest settings; 3. SwingChair – $495 Recommended by a strong contingent of writers, including one of my favorite visual storytellers, Kathy Sierra. I like the design concept, but I would suggest other forms of “core exercise”. 4. Liberty (HS) – $899 (6 reviews; average review: 3.5 stars) 5. Freedom Task Chair with Headrest (HS) – $999.99 (1 review, average: 4 stars) Used at the FBI and by other governmental agencies with three-letter acronyms.
6. Embody – $1,800 list price (negotiated with dealer: $1,200-1,300): Basis of chair design – sitting is bad; Even in locked position, it still has some backward flex at the top position. No forward tilt option. For personal testing, I also added a Swiss-ball chair (Isokinetics Balance Ball Chair – $75) to the mix, as seen below: Surprisingly, the Isokinetics chair is more comfortable than most fixed chairs I tested, though there is some minor… ahem… testicular compression that isn’t nearly as pleasant as it sounds. If you don’t have jewels to worry about, this chair could well be an ideal cost-effective choice. The chair I most wanted to test was the Mirra, which seems to have the best combination of price point (bought used or via eBay) and multiple 5-star reviews. Not to mention it’s also the name of one of the best BMXers of all time. In the end, I bought a used C-size (technically a bit too large for me) Aeron for $450 on Craigslist. I’m impatient and didn’t want to wait over the weekend to schedule sittings for other Herman Miller chairs with a certified dealer.
Once I have some conclusive comparable data, I want closure.I’m 5′ 8″ and 170 lbs., but the C works with no problem. 1) The lumbar support is — by far — the primary determinant of comfort or pain. I’ve lowered this adjustment and found that maintaining the natural S-curve through pressure on the lower back is what prevents pain most consistently. Comfortable sitting time is now 7-8 hours vs. less than 2 hours, with no ill after-effects. Sliding lumbar support on the Aeron. 2) Seat height (and secondarily, depth) will determine the rest. If the flats of your feet don’t make complete contact with the floor, you will move your hips forward and slouch, eliminating the S-curve in the lower lumbar. If your seat is too low and your knees are above your hips, you will shorten the habitual range your hip flexors (negative neural adaptation) and end up with severe lower-back pain. Aim to keep your hamstrings parallel to the floor, and if the seat is too long for your femur (thigh bone) — as is mildly the case with my C-size Aeron — just separate your knees a bit.
If you’re not wearing a tight skirt, I’ve found a basketball of space between the knees to provide the best lateral stabilization, which reduces torso fatigue. Take off heels when sitting at a desk, lest you end up with hot calves and Quasimodo-like posture. Not good for mating. If you are wearing a tight skirt, I suggest taking up the Japanese tea ceremony and sitting on tatami side saddle. It’ll be more comfortable than crossing your legs all day.True, I’ve thought more about chairs in the last few weeks than anyone should, but I do it to save you the trouble. Benefit from my OCD so you can obsess on other things. 3) Using a 3′ long and 6″ diameter foam roller three times per day for 5 minutes can eliminate persistent middle-back pain from mediocre chair use; conversely, it can extend your comfortable sitting time by 30-40%. Knowledge workers often log more ass-in-seat time than sleep. Coders, in particular, are often subjected to a steady diet of Mountain Dew and hunching for 12+-hour marathons.
I don’t put in these hours, but I found myself with severe mid-upper back pain from using a non-adjustable chair and craning over a desk that was too low, even for 30-60 minutes per day. Two doctors suggested various therapies, but a quick experiment (placing a laptop on top of a dresser and writing while standing for two days) proved that posture was the problem. In less than a week following my switch to the Aeron, all upper middle-back (lower trapezius, rhomboid major) pain disappeared completely. The results: better output during work and writing, faster and deeper sleep, and a huge smack on the forehead. Why the hell didn’t I do this earlier? In my case, was it worth it at $450? Particularly looking at the value of time per hour and the lost income due to doctor visits, massage, etc., this is $450 I should have invested years ago.
