  1. David Park

    NEWARK, NJ

    Quality base, quick delivery, easy install. Nothing more to say.

  2. H. Nakamura

    LOS ANGELES, CA

    Called in with a question about whether this base would work with a remanufactured Aeron cylinder, and Lerry knew exactly what to check. He stayed on the line while I looked up my chair model and confirmed everything would work together. Part arrived two days later, installed in 5 minutes, and the whole setup is perfect. Cannot thank Larry enough.

  3. Wendy C.

    SACRAMENTO, CA

    Works perfectly for the classic Aeron.

  4. Thomas G.

    SAN ANTONIO, TX

    I want to give credit where it is due. From the product listing to the packaging to the actual part quality, everything about this order was handled well. The base fits perfectly, shipping was fast, and the chair is back in action. Nulife clearly knows their Herman Miller inventory. Will be back.

  5. Elena V.

    SAN FRANCISCO, CA

    The base on my Aeron snapped after I accidentally rolled it into a concrete step. Was devastated because I love that chair. Found this replacement and the fix was straightforward. Chair is completely restored and I could not be happier.

  6. J. Okonkwo

    COLUMBUS, OH

    Confirmed fit for Size A. No drilling, no adapters, no fuss. Just swap and go. The casters clicked in smoothly and the chair is completely stable on hardwood floors.

  7. Marcus T.

    AUSTIN, TX

    From ordering to install this was a smooth process. The part arrived in good shape, the quality is clearly genuine, and the chair is back to being the best seat in my office. No hesitation recommending this.

  8. A. Patel

    CHARLOTTE, NC

    Popped the casters out, flipped the chair, removed the old base, dropped the new one in. Done. No special tools needed. The base is solid and the chair feels totally secure.

  9. Simone B.

    BROOKLYN, NY

    Small cosmetic mark on the underside of one arm, probably from the manufacturing process. Not visible during normal use at all. The function is perfect and the chair is completely stable. Docking one star just for the cosmetic thing.

  10. Kevin W.

    PHOENIX, AZ

    Third time ordering from Nulife and they have never let me down. The base is genuine quality, arrived well protected, and installed without any fuss. If you have a Herman Miller chair that needs parts, just go to Nulife first and save yourself the searching.

  11. R. Okafor

    HOUSTON, TX

    My Aeron is from 2007 and I was not ready to give it up. This base replacement gave it a new life. Install was straightforward and the chair is as good as ever. So glad I found this.

  12. Patricia Yuen

    SAN DIEGO, CA

    This thing is solid. Much heavier than I expected which tells me the material quality is good. Installed cleanly and the chair has zero wobble. You can feel the build quality.

  13. L.F.

    MIAMI, FL

    Replacement base for a classic Aeron. It is a replacement base for a classic Aeron. Fits, works, looks right. That is all.

  14. D. Nguyen

    SAN JOSE, CA

    Our office manager was ready to toss a perfectly good Aeron just because the base was cracked. I found this part and reached out to Nulife with a question about compatibility. Jerry got back to me within the hour with confirmation it was the right fit. Ordered it, installed it the next day, chair is saved. Thanks Jerry, you are the man.

  15. Carlos Estrada

    PHILADELPHIA, PA

    Finding parts for a pre-2010 Aeron is not easy. This base fits mine perfectly and the quality is exactly what you expect from a Herman Miller component. No wobble, no flex, totally solid.

  16. Angela R.

    BOSTON, MA

    The original base had one cracked spoke that made the whole chair feel unstable. Replaced it with this and honestly the chair now feels better than it has in years. Really glad I repaired instead of replaced.

  17. Brian Collins

    ATLANTA, GA

    Not cheap, but this is a proper OEM replacement and not some generic knockoff. The weight and construction feel exactly right. Chair is completely stable. Worth the money if you want it done properly.

  18. Rachel S.

    MINNEAPOLIS, MN

    Already bought a pivot bolt from Nulife a few months back and had a great experience so came back for the base. Same story, fast shipping, genuine quality part, no surprises. This is my go to for Herman Miller replacement parts now.

  19. Nathan

    SAN FRANCISCO, CA

    10 minutes, one screwdriver, done. Base is sturdy and the chair does not wobble at all now.

  20. M. Hernandez

    DALLAS, TX

    We had two classic Aerons in our conference room with damaged bases. Ordered two of these and both installed without any trouble. Chairs are back in use and look professional again. Good value compared to buying new.

  21. Fiona L.

    NASHVILLE, TN

    The base arrived with a small scuff on one of the arms from what looked like loose packing. Function is completely fine and nobody sees the bottom of the chair anyway, but the packaging could be better for a part this size. Still a solid product.

  22. O. Jensen

    NEW YORK, NY

    Chair had a cracked arm on the base star. This replacement fixed everything. Took about 20 minutes including putting the casters back in. Feels just like when the chair was new.

  23. Priya M.

    SEATTLE, WA

    I was nervous about replacing the base myself since I had never done it before. Larry from the support team sent me a step by step breakdown over email and it made the whole process super easy. The base itself is great quality and swapped in cleanly. Big thanks to Larry for the patience and help.

  24. M.T.

    AUSTIN, TX

    Overall a quality replacement. Four of the five caster sockets accepted the wheels perfectly. The fifth was a little tight and needed a rubber mallet tap to seat fully. Not a dealbreaker at all, just worth mentioning. Chair is rock solid now.

  25. James

    PORTLAND, OR

    Compared it side by side with the original broken base and they are identical. Finish, weight, caster socket spacing all match. Very satisfied.

  26. T. Brenner

    DENVER, CO

    I spent weeks looking for a genuine replacement base for my classic Aeron and nobody had it. Nulife had it listed, shipped it fast, and the quality is exactly what I expected from a Herman Miller part. Chair is back in daily use. Seriously, thank you. You saved me from buying a whole new chair.

  27. Sandra Kowalski

    CHICAGO, IL

    Dropped in without any issues. My Aeron is stable again and the base looks identical to the original. Happy with the purchase.
