  1. Fred Lawton

    Good replacement for an aging chair

    RICHMOND, VA

    My Aeron is getting up there in years and the base was showing it. This replacement gave the chair a new lease on life. Solid build and a clean look. Good value compared to buying a new chair.

    Smooth install, great result

    KANSAS CITY, MO

    Followed the six steps on the product page and everything went smoothly. The hardest part was separating the old base but a few firm mallet taps did it. New base looks great and there is zero wobble. Highly recommend.

    Good quality aluminum

    SEATTLE, WA

    You can tell this is well made just by picking it up. Heavy, solid, no flex in the legs. Fits exactly as described for the classic Aeron. Very satisfied.

    Chair back in action

    PITTSBURGH, PA

    My Aeron base had been cracked for a long time and I kept putting off fixing it. Finally ordered this and got it done in one afternoon. Chair feels like I just bought it. Very happy I finally pulled the trigger.

    Works perfectly

    Mallet required, have one ready

    LAS VEGAS, NV

    Just a heads up for anyone ordering this: the old base will not come off by hand. You need a rubber mallet and you need to hit it a few times. Once off, the new base goes on easily. The end result is a very stable chair. Just go in prepared.

    My second order from Nulife

    COLUMBUS, OH

    Already ordered arm pads from Nulife Chairs a few months back and had a good experience. This base is just as good. Consistent quality and the parts always fit right. Will keep coming back.

    A little pricey but worth it

    ATLANTA, GA

    150 dollars felt steep at first but considering it’s an aluminum base for a premium chair it makes sense. The quality is there. Chair is solid and I expect this base to last many years.

    Sturdy and well finished

    HOUSTON, TX

    The aluminum looks great and feels very solid. No sharp edges or rough spots. The legs are evenly spaced and the whole thing is well balanced. Very pleased with the quality.

    Lerry was super helpful

    SAN FRANCISCO, CA

    I reached out before ordering because my Aeron is a bit older and I wanted to make sure the base would fit. Lerry confirmed the compatibility and walked me through what to expect during install. Base arrived, fit perfectly, and chair feels like new. Great experience start to finish.

    Good product, clear instructions

    SAN DIEGO, CA

    The installation guide was clear and accurate. I appreciated knowing I needed a rubber mallet beforehand since I had to go find one. Base fits great and the chair is stable. Good price for a quality aluminum base.

  12. Naomi Fisher

    Chair stopped wobbling immediately

    CHARLOTTE, NC

    Swapped the base and the difference was immediate. No more side to side wobble. The old base had one leg that had bent slightly and I’d just been living with it. Should have done this sooner.

    Exactly as described

    AUSTIN, TX

    No surprises. The base matched my classic Aeron perfectly. Packaging was good, no damage. Install went smoothly. Would buy from Nulife again.

    Great find for Aeron owners

    PHILADELPHIA, PA

    I had no idea you could even buy a replacement base for an Aeron until I found Nulife Chairs. Ordered it, followed the steps, and my 12-year-old chair is now completely stable. Saved me from spending hundreds on a new one.

  16. Amy Cho

    Solid upgrade

    SAN JOSE, CA

    Replaced a base that had been cracking for a while. This one feels much sturdier. No wobble at all. Took about 10 minutes with a rubber mallet.

    Good base, shipping took a while

    MINNEAPOLIS, MN

    The base itself is excellent. Solid build and fit my chair well. Only reason I’m not giving 5 stars is that shipping took almost two weeks to reach me. Would have liked faster delivery for the price.

  18. Marcus Abrams

    Worth every dollar

    NASHVILLE, TN

    My Aeron base snapped after I accidentally rolled it into a wall one too many times. Buying a new chair wasn’t in the budget so I looked for a replacement base. Found this and it was exactly what I needed. Install was straightforward. Chair works perfectly again.

    Looks and feels original

    CHICAGO, IL

    Honestly looks just like the factory base. Clean finish, no rough edges. My Aeron has been through a lot and this brought it back to looking presentable. Happy with it.

    Took a bit of force to remove old base

    PORTLAND, OR

    The installation guide says rubber mallet and they mean it. The old base was really stuck on the gas cylinder. Took quite a bit of effort to separate them. Once I got that done the new base went on cleanly. End result is great, just be prepared for that step.

    Fit perfectly on my classic Aeron

    BOSTON, MA

    I was nervous about ordering a base replacement online but it fit my classic Aeron without any issues. The cylinder slotted in correctly and the casters went right back in. Very satisfied.

    Heavy but worth it

    SEATTLE, WA

    This thing is solid and heavier than I expected. The die-cast aluminum feels really well made. Install took me about 15 minutes including getting the old base off. Chair feels brand new.

    Chair is steady again

    LOS ANGELES, CA

    One of the legs on my old base had cracked and the whole chair wobbled badly. This replacement base went on without much trouble. Flipped the chair, used a rubber mallet to get the cylinder seated, popped the casters back in. Chair is completely steady now.
