Herman Miller Aeron Chair Highly Adjustable with PostureFit Lumbar Support - Medium Size (B) Graphite Dark Frame, Waves Platinum Pellicle Mesh Home Office Desk Task Chair

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.

This chair is pretty expensive. But then I thought that if I study a lot, I would need a good chair.I heard about this chair from a book called "Ichinichi 30 Pun wo Tsuzukenasai" by Yukio Huruichi. He recommended this chair and emphasized how important it is to invest on chair.I did hesitate when I saw this in amazon because I thought the price would be at most $300. But alas, it was near $900. Took me a few days whether to buy it and I now can say it is worth buying it.First, it was very easy to assemble. Just follow along the user's manual. The only one that took me long was putting the cable through the fabric. Other than that, it was breeze.Second, the chair is soft but firm enough to hold you up steady. I feel more light after seating on this chair and my spine feels less strained compared to any chairs I ever sat before.Third, I like its design.Fourth, the forward tilt is probably the best feature for people who study a lot. It is the best feature of this chair.The only problem is that it doesn't seem tilting back enough when reclining. But my purpose of using chair is to study with a good posture, not to take break and sit back.I haven't tried Aeron's sister product Mirra chairs yet but at least I am satisfied with Aeron. I am sitting on it now, and it ia so comfortable. It makes me feel aligning my sitting posture correctly without getting any message.
