This is the second upgrade I have recently done to my Aeron Chair. This is even better than the pellicle fabric headrest as far as improving the Aeron for my back. I have enjoyed my Aeron Chair for over 10 years and even before these recent upgrades the chair has been a real benefit for my bad lower back (spondylolisthesis at L5). I decided to try the Posture Fit kit after reading the positive reviews here on Amazon. However I was concerned about the negative reviews posted here as well.

Let me reassure you, don't be influenced by the negative reviews! If you are currently sitting in an Aeron chair with the old lumbar pad you will love this upgrade. This kit offers vastly improved support. Yes, it takes about 10-15 minutes and some patience to install but it is relatively easy and well worth the effort.

The "butterfly pad" seems to rotate the pelvis forward by applying just the right amount of adjustable pressure to the lumbar area of the lower back. My only wish is that I had the Posture Fit and the headrest from the beginning. These improvements have transformed my chair into a precisely supportive cloud for my back. I am ecstatic - it feels like a new chair. The other add-on I highly recommend is:Headrest for Herman Miller Aeron Chair I believe both of these are "must-have" items for this great chair.

I am baffled by the negative reviews of this item, the installation was easy and the results outstanding.

Note: My wife has a healthy back and she loves the chair now so much I am afraid I am going to have to buy another. After installing the Posture Fit and sitting in the chair she exclaimed "Oh wow!" I concur.

UPDATE: 20 months later, still loving this modification to my Aeron Chair. The PostureFit support kit was a great add-on. Highly recommended.

If you are seriously thinking about it just stop right now and BUY IT.

I recently strained my lower back and decided to purchase the PostureFit. After sitting in it for a week I can safely say I wish I bought it when I got the chair. It is not lumbar support. It actually works to strengthen your lumbar and straighten your spine by forcing the pelvis forward. Just Google "PostureFit Design Story"

If your only worry is the installation, just stop right now and BUY IT.

It's super easy to install. There is a little booklet with instructions a child could follow. There are also installation videos online. If you know what you're doing it takes about 5 minutes. Expect to spend 15 minutes or so if it is your first. The wire is blunt tipped and is never in danger of damaging the chair.

The lumbar pad pushes below your typical lumbar curve, and doesn't provide full lumbar support. This, in combination with the foam pad, would perhaps work. Yet, you can't add both (or can you)? I added a rolled towel between the upper arms and fixed the support issue.

Others are correct that this does have a strange installation. It was a bit difficult and took me about fifteen minutes, just to install it; I expected it to take 30 seconds. With that said, it's much better than the lumbar support that comes with the aeron. The lumbar support dug into my back and this can be adjusted a decent amount, but I wish it had more flex. If you want more back support than the aeron chair by itself (but not the back biting lumbar), then get this.
$85 is a bit expensive for this though.

I agree with some of the comments here from both angles. This device does seem to be a bit of a hack. It does provide minimal support but it's all plastic, hardly worth $100+ when it probably costs about 15 bucks to make. The instructions are confusing, partially because they're in tiny text with terrible drawings. Am I happy I bought it, yea. It's makes a great comfortable chair slightly better.

I agree with the other reviewers, this kit provides good support, but only if you need it in exactly the spot Herman Miller chose for you. It would have been much better if the pad could slide up or down so that it is possible to locate it more comfortably. Installation is relatively easy, but the need to punch a hole through the fabric as well as the installation of the control unit feel like an afterthought and not the level of design you'd expect from a company like Herman Miller or from an expensive chair like the Aeron. It is a shame that the choice is between a kludgy device and the foam pad which breaks about once every two years.

This is much better than the original lumbar (I've gone through two of them). The original Herman Miller lumbar tears apart at the ends (I'm actually a fairly thin-build person so I was surprise that my body weight was too much for the original lumbar to handle.

This newer model lumbar adds an adjustment knob to the side of the chair frame to adjust how far out the lumbar pushes. It does NOT adjust up/down (it would be nice if I could adjust it up just slightly higher.) Had it had a height adjustment, I'd have given them 5 stars.

It was mostly easy to install but teasing the end of the lumbar adjustment cable through the fabric took several attempts. They suggest you use a wood pencil to spread the coarse fibers of the chair fabric apart to make it easier to insert the cable -- this does NOT tear the fabric because the fabric tends to want to return to it's original shape -- meaning if you don't get the cable threaded through quickly the hole you opened up will close back down again.
