  1. Monica Hayes

    Back support night and day

    NASHVILLE, TN

    I didn’t realize how bad my old frame had gotten until I sat in the chair after installing this one. The back support is completely different. Firm, even, and properly shaped. My posture has already improved after just a few days.

  2. R. Okafor

    Packaging was excellent

    RICHMOND, VA

    This is a large part so I was worried about damage in transit. It was packed really well with plenty of protection. Arrived in perfect condition and installed without any problems.

    Very satisfied

    SAN FRANCISCO, CA

    Ordered size B complete. Arrived in good shape. Installed it in about 12 minutes with no issues. Chair back is firm, even, and comfortable. Exactly what I needed.

    Size C fits my large Aeron

    PHOENIX, AZ

    Finding size C parts is not always easy but this was available and fit correctly. Mounting holes lined up, bolts went in clean, and the back feels firm and supportive. Good product.

  5. P.R. Castillo

    Great part, would reorder

    ALBUQUERQUE, NM

    The back frame is solid and the mesh sits with even tension across the whole surface. My chair had been uncomfortable for months because of the cracked frame. This fixed it completely. Would order again without hesitation.

  7. G. Nakamura

    Took a little longer than listed

    SEATTLE, WA

    Install guide says 10 to 15 minutes but mine took closer to 25. The old bolts were really stuck. Once those were out everything else was easy. End result is good and the chair is solid.

  8. Henry Park

    Good value compared to a new chair

    BALTIMORE, MD

    A new Aeron would cost over a thousand dollars. This back frame is a small fraction of that and brings the chair back to full function. For anyone on the fence, it’s worth it.

  9. Phil Osei

    Solid repair for less than a new chair

    PHILADELPHIA, PA

    This is an expensive part compared to small repairs but given what a new Aeron costs it’s completely justified. Frame quality is excellent and the install was clean. My chair is fully restored and I expect it to last many more years.

  10. Sarah Quinn

    Quick and clean install

    TAMPA, FL

    Followed the six steps on the page and had it done in under 15 minutes. No issues with alignment and all four bolts tightened evenly. Highly recommend going with Torx T25 as stated, no shortcuts.

  11. Nadia Kowalski

    Aeron restored

    PITTSBURGH, PA

    My Aeron is probably 13 years old. The back frame had cracked along one of the lower corners and the whole back was slightly off. This replacement frame fixed all of that. Chair sits and feels like it did when it was new.

    Nulife is my go-to for Aeron parts

    BOSTON, MA

    I’ve repaired two Aerons now using parts from Nulife Chairs and the quality has been consistent every time. This back frame was no different. Good fit, solid materials, and the chair is back to being a great place to spend 8 hours a day.

    Third Nulife order and still happy

    DENVER, CO

    I’ve now ordered arm pads, casters, and this back frame from Nulife Chairs. Every part has been good quality and fit right. Consistent experience across the board. Will keep coming back for any other repairs.

  14. Omar Diaz

    Great for a DIY chair repair

    DALLAS, TX

    I enjoy fixing things myself and this was a satisfying repair. The instructions on the product page are clear. Torx T25 is all you need. The new back frame gives the chair a fresh feel and the back support is noticeably better than what I had been sitting on.

  15. D.J. Ruiz

    Chair is stable and supportive again

    AUSTIN, TX

    The back frame on my Aeron had been slowly bending out of shape. I noticed my posture getting worse and eventually traced it back to the frame. This replacement sorted it out completely. Well worth doing.

  16. C. Holloway

    Not bad, minor finish issue

    KANSAS CITY, MO

    The frame works fine and installed without problems. There was a very faint scratch on the upper left corner of the frame that looked like it happened before packaging. Doesn’t affect anything but I noticed it. Still happy overall.

  17. Kevin Tran

    Came packaged well

    HOUSTON, TX

    The frame was wrapped carefully and arrived without any damage. For a part this size I was relieved. Install went smoothly and the chair is back in great shape.

    Well worth the price

    NEW YORK, NY

    I debated for a while about spending this much on a back frame. In the end it was the right call. The quality is there and my Aeron is going to last another decade at least. Much better than the alternative.

  19. Cassie T.

    Would buy from Nulife again

    DENVER, CO

    Good quality part, reasonable pricing considering what it is, and the process was smooth. Back support is fully restored. I have nothing negative to say.

  20. Lisa Pham

    Frame only option worked fine for me

    SACRAMENTO, CA

    Went with the frame only option since my mesh was still in decent shape. It transferred over without any trouble. Saved a bit of money and the result is the same. Chair is comfortable and stable.

    Lumbar support is back

    LAS VEGAS, NV

    My Aeron back had been gradually losing its shape over the years. The PostureFit wasn’t doing much because the frame itself was warped. New frame fixed everything. Lumbar support is back to how it should be and I can sit for hours without discomfort.

  23. Y. Watanabe

    Frame only worked out great

    SEATTLE, WA

    My mesh was still in good shape so frame only made sense. It came without the mesh and I was able to use my existing one. Saved money and the repair looks completely seamless.

    Exactly what was described

    SAN ANTONIO, TX

    No surprises. Ordered size B complete, received what I expected, installed it in 15 minutes. Chair back to normal. Good experience.

  25. chairbuilder_hal

    Great for refurbishing an old chair

    PHILADELPHIA, PA

    I picked up a cheap used Aeron at an office sale knowing the back was damaged. Between this back frame and a new arm pad set I have a great chair for a fraction of retail. This site is a goldmine for Aeron owners.

  26. Frank Oduya

    Good experience from start to finish

    CHARLOTTE, NC

    Ordering was simple, shipping was within a reasonable timeframe, and the part fit perfectly. The back frame feels just like the original. My 10 year old Aeron has a new lease on life and I didn’t have to spend a fortune.

  27. Mike Larsen

    One bolt hole needed extra alignment

    COLUMBUS, OH

    Three of the four mounting bolts went in perfectly. The fourth needed a little wiggling to align. Nothing major but worth knowing it might not be a completely effortless install. Chair is solid once it’s all in.

  28. N. Osei

    Better than expected

    ATLANTA, GA

    I was a bit worried ordering a back frame online for this much money but it paid off. The quality is solid, the fit is correct, and my Aeron is back to being the chair it was when I first got it years ago.

  29. Priya Menon

    Exactly what I needed

    LOS ANGELES, CA

    My Aeron back had a hairline crack that had slowly gotten worse. Replaced it with this and the chair is completely fixed. Clean install, good quality part.

  30. Angela Morales

    Mesh alignment is spot on

    PHOENIX, AZ

    The mesh on the new back frame lines up perfectly. No sagging or uneven tension anywhere. This is clearly made to the right spec for the classic Aeron.

  32. Tom Reeves

    Complete frame option is the way to go

    NASHVILLE, TN

    I went with the complete option instead of frame only since I wanted everything fresh. Came well packaged and the install was clean. All four mounting holes aligned without any forcing.

  33. M. Johansson

    Decent but pricey

    MINNEAPOLIS, MN

    The frame is good quality and the fit was correct. Just feels steep at $250 for size C. That said it did fix the chair so I can’t really complain too much.

  34. Fiona Walsh

    Back pain is gone

    DENVER, CO

    My cracked back frame meant the mesh wasn’t sitting right and my lower back was paying for it. Replaced the frame and within a day my back stopped aching. The posture support is back to what it should be.

    Works great for a used Aeron

    Bought a used Aeron that had a cracked back frame and this fixed it completely. Chair now looks and feels like a proper premium seat. Good value.

  36. Paul Nakamura

    Easy install, great result

    SAN FRANCISCO, CA

    Four bolts with a Torx T25 and you’re done. The alignment was spot on and the back is rock solid. My Aeron is back to being the best chair in the house.

    Lerry helped me pick the right size

    LOS ANGELES, CA

    I wasn’t sure if my chair was a B or C size. Reached out and Lerry walked me through how to check and confirmed I needed a B. Ordered it and the fit was perfect. Really appreciate that kind of help before buying a $200 part.

  38. L. Brandt

    Minor creak after install

    COLUMBUS, OH

    Chair back is solid but there is a faint creak when I lean back. Not sure if it’s the frame or something else. Everything is tightened properly. Might go away with use. Otherwise the frame looks and fits great.

  40. T.B.

    Good but shipping was slow

    HOUSTON, TX

    Took about 12 days to arrive which felt long. The frame itself is great quality and installed without any issues. Just wish the shipping was faster for a $180 purchase.

  41. Andy Lim

    Happy with the complete option

    SAN JOSE, CA

    Went complete instead of frame only. Everything was fresh and there was no messing around with transferring parts. Install was clean and the chair looks and feels great.

  42. Derek Wills

    Saved me $800

    CHICAGO, IL

    I looked at buying a new Aeron and the price was not happening. My back frame was cracked and sagging. This replacement was a fraction of the cost and the chair feels like I just pulled it out of the box. Install took me about 15 minutes. Very happy.

  43. Irene Bautista

    Size A fits my small Aeron

    SAN DIEGO, CA

    I have a size A Aeron which is harder to find parts for. This fit correctly and the install was straightforward. Very happy it was available in all three sizes.

    Chair feels like new

    PORTLAND, OR

    My old back frame had a crack running along one side and I kept ignoring it. Finally replaced it with this and the difference is huge. The mesh sits correctly again and my lower back thanks me.

    Back frame fits perfectly

    SEATTLE, WA

    Ordered size B and it lined up with the mounting holes perfectly. Four bolts, Torx T25, done in about 12 minutes. Back support is solid again.
