Aeron Size B - Posture Fit, Graphite, Classic Carbon Pellicle

Posture Fit vs. LumbarGot this one (with posture fit) for my home office. I have an identical one with lumbar support at my work office. I like to feel the support on my back. I feel the lumbar more than the posture fit. BUT, the lumbar support is felt all across the lower back, while posture fit is designed to keep your spine straight. I came across a report from a study comparing lumbar vs. posture fit using 80+ participants. The study found that posture fit improved their spine in most cases on most measurements. I am generally skeptical of studies like these, but after using posture fit for a couple of weeks I don't get that numb feeling in my back after sitting for a long time. So I like it more than lumbar. The caveat seems to be - you need to push your butt as far as you can against the back of the chair (the proper way of sitting). If you tend to sit on your lower back with your butt on the rim of the chair - no lumbar or posture fit will help you. It is not too hard to correct the posture, but it's definitely a conscious effort. Just an FYI.Construction of the ChairThe chair is very sturdy and quiet when turn around, etc. You can definitely tell that it's top quality. Should last a very long time based on the feel of it and the history of Aerons. It has the standard Aeron adjustment features. Its mesh material is simply the best that I've tried. It's not cuddly like leather, but feels good and airs well, so you never have a sweaty back, etc.My ConclusionI honestly don't know how an office chair can get any better for my requirements: comfortable, good for back, sturdy, and quiet. The only thing that could improve it is a massager of the back (ok, I am kidding). Got it for $660 in "used - like new" condition. Perfect for the price.

The completed chair is fine. I had one for years at my old job. My wife has has one for several years in her home office. The problem is the assembly.The chair I bought for my wife several years ago was no problem to assemble; it took about 15 minutes. The one I just received was another matter.There are two major problems with the assembly required on this chair. The first is that I am expecting "some assembly required" to mean that the manufacturer has a complete chair that had to be disassembled into a few pieces in order to ship and that I am going to be expected to reassemble the chair. That's not the case here. This more of a "we offer six different models of chair so we're going to send you the base model and you're going to build your own chair by adding accessories that vary by model." The very first instruction was to remove a screw that was already in the chair and drill a hole to accommodate the accessories required for my model. The hole don't come pre-drilled? On a chair that costs almost $1,000? Really? I have to drill it myself and, if I make a mistake, I have ruined a $1,000 piece of furniture.The second problem is that while the chair might seem very 2016, the instructions are very 1916. Confusing, poorly worded instructions along with crappy illustrations on a piece of tissue paper. It's about what you'd expect with a cheap child's toy manufactured in a non-English-speaking country. No photos. No labeling of items. Essential pieces are left out of the instructions while extremely basic things are both mentioned and illustrated. Plus, there are two separate sets of instructions. And, to top it all off, some of the pieces didn't quite fit properly.I sent it back. If I wanted a poorly made, do-it-yourself office chair kit, I would have spent $40 on a clearance chair from Ikea (which is what this reminded me of). Spending $1,000 on a Herman Miller, I expected far better.

My job is in engineering, so I spend a lot of time at my desk in front of my computer. The various offices I have worked in had a majority of chairs being the Aeron, but I had a hard time justifying the cost of buying the chair for own use at home. $800+ is a lot to spend on a chair. After a few years of going through a few different chairs, I'm happy I bit the bullet and purchased one of these.Not everyone will find these chairs comfortable. It's always a matter of personal preference, but the comfort this chair provides is well worth the price. It's not leather, doesn't look like an executive chair, but after going through a few of those chairs (at $200 - 300 a piece) over the past few years, the cost added up and I could have bought an Aeron. The seat mesh doesn't support like memory foam does, but the chair as a whole is very supportive and I can sit for hours without any issues. Other chairs I would eventually get cramps in my legs or lower back, but I never experienced that with the Aeron, even after 10 hour workdays and then going home to this chair to work for a few hours more.The hardest thing to swallow is the initial price, but the warranty is good (although I haven't had to use it) and the chair is a complete workhorse. In the most recent office that I have worked in, I haven't seen any Aeron chairs replaced or worn out. The cheaper chairs only last two years or so before headed to the dumpster. I'm pretty sure there are plenty of Aeron chairs in my current office that are over a decade old. If you are buying a new computer chair every two or three years at a few hundred a chair, this will eventually pay for itself without your legs or back paying for it.
