  1. Penny Gallagher

    Simple part that makes a huge difference

    BALTIMORE, MD

    You do not think about the lumbar pad until it is gone. Once mine cracked I realized just how much it was contributing to my comfort. This replacement is just as good and I will not be going without one again.

  2. TC

    No wobble after months of use

    OAKLAND, CA

    I have had this on my chair for about three months now and it has not shifted or loosened at all. Stays firmly in place and still provides the same support it did on day one.

  3. Audrey Spence

    Lerry helped me verify the right size

    KANSAS CITY, MO

    Contacted Nulife to double check sizing before I ordered and Lerry confirmed this was the right fit for my classic B frame. Arrived quickly and the install was as easy as described.

  4. RF

    Chair back to day one condition

    ORLANDO, FL

    My Aeron is probably 10 years old and replacing worn out parts like this brings it back to feeling brand new. The lumbar pad was the last piece and now everything is solid again.

  5. Celeste Nguyen

    Good replacement for a broken pad

    TAMPA, FL

    My original pad had a crack right through the middle. This replacement looks and feels just as good. No visible difference from the outside and the support is back to normal.

  6. YP

    Two minute job, lasting comfort

    WASHINGTON, DC

    Put it on in literally two minutes with no tools. That was three months ago and it has not moved or worn down. My lower back has never felt better during work hours.

  7. Brennan O’Shea

    Worth it at twice the price

    PITTSBURGH, PA

    For what this part does for your comfort and posture I think $40 is a steal. I spend 8 hours a day in this chair and the lumbar pad is not something I am going without again.

  8. HT

    Size B fit is spot on

    SAN FRANCISCO, CA

    If you have a classic Aeron size B this fits without any modification. No forcing, no adjusting. Just slides right on and sits properly.

  9. Sabrina Caldwell

    Replaced mine after years of wear

    PORTLAND, OR

    My original lumbar pad had flattened out to the point where it was not doing anything. This replacement feels like the chair did when I first bought it. Really noticeable improvement.

  10. MJ

    Nulife had great communication

    SAN JOSE, CA

    Had a question about the return policy and the team at Nulife Chairs got back to me quickly. Good customer service and the part itself is solid. Easy install and works great.

  11. Quincy Barlow

    Turned a painful chair into a great one

    CHICAGO, IL

    Sitting without lumbar support for months had made my Aeron borderline unusable for long sessions. This fixed that completely. My lower back feels supported again and I can actually focus on work.

  12. GF

    Good product, slight delay in shipping

    BOSTON, MA

    The lumbar pad itself is great and fits perfectly. Only reason for four stars is that shipping took a little longer than the estimate. Once it arrived everything was fine.

  13. Isabella Torres

    Holds position throughout the day

    LOS ANGELES, CA

    I was worried it would slide down over time but it has stayed exactly where I positioned it. The grip on the rails is solid. Still in the same spot after months of use.

  14. SK

    Good value, honest review

    DALLAS, TX

    It is a replacement lumbar pad. It fits the size B Aeron. It provides good lower back support. The price is fair. No issues in two months of use.

  15. Walter Nduka

    Chair is comfortable again

    ATLANTA, GA

    That is really all I need to say. Missing lumbar pad, ordered this, installed in two minutes, chair is comfortable again. Five stars.

  16. OP

    Exact match to the original

    SEATTLE, WA

    Compared this to photos of the OEM part and they look identical. The material, the shape, and the way it clips onto the rails all match up. No complaints from me.

  17. Lenora Fairbanks

    My chiropractor noticed the difference

    MINNEAPOLIS, MN

    My chiropractor actually commented that my posture looked better at my last visit. I told her I finally replaced the lumbar pad on my Aeron. She was not surprised. This little part makes a big difference.

  18. CB

    Arrived well packaged

    CHARLOTTE, NC

    Came in a solid box with no damage. Part looked clean and unused. Fit my chair right away without any issues. Would order from Nulife again.

  19. Zara Whitfield

    Sliding mechanism is smooth

    NASHVILLE, TN

    Adjusting it up and down along the rails is effortless. I moved it a few times to find the right height and it glides without sticking. Good build quality.

  20. EV

    Lerry confirmed this was the right part

    AUSTIN, TX

    I messaged Nulife before ordering to make sure I was getting the right size. Lerry replied quickly and confirmed this was the correct one for my classic Aeron B. Part arrived fast and fit perfectly.

  21. Rodrigo Mendez

    Great fix for a used Aeron

    SAN DIEGO, CA

    Picked up a secondhand Aeron without a lumbar pad and this was the perfect solution. Chair now feels complete and really comfortable for long work sessions.

  22. Harriet Bloom

    Cushion holds its shape

    DENVER, CO

    A few months in and the pad still holds its shape well. No sagging, no flattening. It maintains consistent support throughout the day which is what matters most.

  23. WB

    No instructions needed

    SALT LAKE CITY, UT

    The product listing says it takes 1 to 2 minutes and that is accurate. Just slide it on, position it where you want, and you are set. No confusion at all.

  24. Desmond Holt

    Posture is noticeably better

    SACRAMENTO, CA

    I did not realize how much the lumbar pad was doing until mine broke. Three weeks in with this replacement and I can already tell my posture has improved. Less slouching, less aching at the end of the day.

  25. TR

    Solid quality for the price

    BUFFALO, NY

    At $40 this is a great deal. The pad feels sturdy, it fits the rails perfectly, and after a few weeks of daily use it has not shifted at all. Worth every penny.

  26. Nneka Ibe

    Brought the chair back to life

    HOUSTON, TX

    My Aeron was almost going to the donation bin because it felt so uncomfortable without the lumbar support. Glad I found this first. Chair is great again.

  27. Felix Drummond

    Easy one minute install

    LOUISVILLE, KY

    Herman Miller says no tools needed and they mean it. Slid this right on from the back, pushed it to where I wanted it, and sat down. Done.

  28. AH

    Better than expected honestly

    PORTLAND, OR

    Was not sure if an aftermarket pad would feel the same but this is really good. Sits right, feels right, no complaints at all.

  29. Colette Jennings

    This saved my work from home setup

    RALEIGH, NC

    I work 9 hours a day at my desk and without the lumbar pad my Aeron was just not cutting it anymore. This replacement brings back that signature Herman Miller feel. My posture has improved noticeably in the past few weeks.

  30. PO

    Fast shipping, good part

    MEMPHIS, TN

    Order came in about 4 days. Part fits well and the lower back support is back. Simple as that.

  31. Vivienne Cross

    Cheap fix for an expensive chair problem

    CLEVELAND, OH

    Spending $40 instead of buying a whole new chair is a no brainer. This pad restores the lumbar support to what it was when the chair was new. The material feels durable and it has not shifted or moved since I installed it.

  32. LN

    Exactly the right fit for size B

    INDIANAPOLIS, IN

    Confirmed this works on the classic Aeron size B. Slides on from the back of the chair and locks in. No wobble, no play. Good product.

  33. Jerome Patel

    Back pain gone after day one

    SAN ANTONIO, TX

    I had been sitting without a lumbar pad for a couple of months and my lower back was really feeling it. Put this in and the difference was immediate. Highly recommend not waiting as long as I did.

  34. BW

    Lumbar pad was the only thing wrong

    COLUMBUS, OH

    My Aeron was in perfect shape except the lumbar pad had cracked down the middle. This replacement sorted it out without me having to spend money on a new chair. Really happy with the quality.

  35. Tiffany Rourke

    Slid right onto the backrest rails

    PHOENIX, AZ

    No tools, no fuss. Took maybe two minutes from opening the package to being back in my chair. The lumbar pad sits exactly where it should and the support feels just like the original.
