Product Description

Size: Size B (Medium) | Color: Graphite

Herman Miller's patented PostureFit provides back support at the base of your spine, or sacral region, helping your pelvis maintain a natural forward tilt to prevent slouching. By doing so, PostureFit keeps your spine in healthy alignment to help eliminate lower back pain. The Aeron PostureFit Support Kit is recommended for people who sit up straight in their chair to perform tasks. It is compatible with all sizes (A, B, or C) of Aeron Chair and Aeron Stools, provided the chair has a Tilt Limiter option. To identify whether your Aeron has a Tilt Limiter, reach down with your left hand while sitting in the chair; if you locate one or two levers attached to the chair's tilt mechanism, your Aeron has a Tilt Limiter.

To find the size of an Aeron Chair, stand behind the chair and feel for the raised dots under the top edge of the back frame. One dot is Small size, two dots in a row is Medium size, three dots in a triangle is Large size.

Care & Maintenance:

For normal cleaning, wash plastic surfaces with a soft cloth soaked in mild detergent and warm water. Rinse thoroughly and dry with a soft cloth. Do not use solvents or abrasive kitchen cleaners.

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.

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.

The foam lumbar cushion that originally came with my Aeron chair cracked and I wanted to replace it with the more aesthetic support kit, but my usual store asked for the serial number of my chair and told me that my chair was an older type that wouldn't take the kit. Still, I went ahead and ordered it, and although the fit is probably tighter than intended, I was still able to install it on my chair with no problem.

The new kit provides much better support than the old foam lumbar cushion. I had to constantly adjust the position of the lumbar cushion because it would cut into my back and become uncomfortable. On the other hand, the new kit presents a much larger supporting surface and its tension can be adjusted with a lever. As a result, the chair is comfortable even during extended use.

Conclusion: It's a wonderful upgrade well worth the price, and it looks great too.

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.

I bought this kit because the regular lumbar support kept splitting (since it's basically made of foam). While this looks like it will be more durable than the lumbar support, and does provide some support - I found the design of the kit and the installation wanting. Despite Herman Miller's reputation for elegant design, this kit feel like a hack, requiring you to stretch (and potentially tear) into the pellicle backing of the chair in order to run a control cable thru. I guess I expected better from HM.

This attachment is an improvement over the standard lumbar support. It supports the sacro area and counteracts the feeling of falling back into a hole and trying to climb out which is what I get with the standard Aeron chair. It was fairly easy to install myself without having to call our facilities maintenance dept. The exact size screwdriver required for your model is listed on the directions. Take care when ordering that you get the right size PostureFit. It's not well known that the chairs come in A, B, and C sizes and most companies only get B. Instructions for finding your chair size are easily found on the web.
