    Comfortable from day one

    NASHVILLE, TN

    No break in period. Pressed the foam in and sat down and it was immediately more comfortable than the worn out piece I had been dealing with. Clean install, good quality, and the seat edge feels properly padded again.

    Only for size B, check your chair

    TAMPA, FL

    Works perfectly but just a reminder this is size B only. I have a B and it fit exactly right. Make sure you know your chair size before ordering. The foam itself is good quality and the install is very straightforward.

    Good repair for the price

    SAN FRANCISCO, CA

    One of the cheapest repairs I’ve made to my Aeron and one of the ones I notice most. The front edge is padded again and the difference in comfort over a long work day is real.

  4. Aaron Dunn

    Softer than expected in a good way

    RALEIGH, NC

    The new foam feels softer than my old flattened piece which makes sense. Comfortable right away and the seat edge no longer feels harsh after a few hours of sitting.

  5. S.J. Park

    Arrived in good shape

    LAS VEGAS, NV

    Thigh pressure is gone

    DENVER, CO

    I sit for long stretches and the bare seat edge was pressing into the back of my thighs. Replaced the foam and that pressure is completely gone. Simple fix for something that was affecting me every day.

  7. F. Yamamoto

    Holds firm after two months

    BOSTON, MA

    Two months of daily use and the foam has not shifted or peeled at all. I pressed it in firmly on install and it has stayed put. Comfort is consistent and the seat edge still feels padded.

  8. Lucy Ferris

    Very affordable fix

    SEATTLE, WA

    Was expecting to pay more for an Aeron part. Thirty dollars is a great price for how much comfort it restores. No tools needed, quick install, and the seat edge is soft again.

  9. W. Okonkwo

    Minor alignment issue at first

    DALLAS, TX

    First time pressing it in I got it slightly off center. Peeled it back and repositioned without any damage to the foam. Second attempt was perfect. Just take your time aligning before you press it fully into place.

  10. H. Brennan

    Good eco choice

    PORTLAND, OR

    I like that replacing one worn part keeps the whole chair out of the landfill. This foam piece cost me $30 and extended the life of my Aeron by years. Good quality and good values all around.

  12. Diane Ross

    Chair feels brand new again

    ATLANTA, GA

    Combined this foam replacement with a new set of arm pads and my Aeron genuinely feels like it came out of the box. Very happy with both purchases. Nulife has everything you need to refresh one of these chairs.

  13. Jason Hollis

    Small part, big comfort improvement

    CHARLOTTE, NC

    I had no idea this small piece of foam at the front edge of the seat made such a difference. Once it flattened out the whole sitting experience changed for the worse. This replacement brought it back completely.

  14. Angela Kwan

    Foam held in place well

    SAN DIEGO, CA

    A month in and the foam is still firmly in place with no shifting or peeling. Press it in firmly when installing and it stays. Good quality adhesion.

  15. Priya Mehta

    Lerry helped me confirm this was the right part

    SAN JOSE, CA

    I was not sure if this foam piece was what was causing my discomfort or something else. Reached out to Nulife and Lerry walked me through it and confirmed this was what I needed. Ordered it, replaced it, and the difference was clear right away.

  16. Oliver Grant

    Took about 10 minutes total

    MINNEAPOLIS, MN

    I removed the seat frame first for easier access as the guide suggested. Made peeling off the old foam and pressing in the new piece straightforward. Back in place and feeling good.

    Exactly what was needed

    NASHVILLE, TN

    Foam was crumbling off my old Aeron. This replaced it cleanly. Sits correctly and the front seat edge is comfortable again.

  18. Chloe Park

    Fixed my used Aeron

    LOS ANGELES, CA

    Bought a used Aeron that had flattened seat foam. This was one of the first things I replaced and it made a big difference. Chair is comfortable and the foam looks correct in place.

    Cheap fix for real comfort

    HOUSTON, TX

    Thirty dollars and my chair is noticeably more comfortable for long sitting sessions. The foam presses firmly into place and shows no signs of shifting after a month of daily use.

    Legs no longer go numb

    DENVER, CO

    I had been getting numbness in my legs during long meetings and blamed it on posture. Turned out the foam edge of my seat had worn flat and was cutting off circulation. This fix solved the problem completely.

  21. Mike Carver

    Took a flathead to help remove old foam

    PORTLAND, OR

    The old foam had basically bonded to the seat over the years. Needed a flathead screwdriver to help peel it off carefully. New foam pressed in cleanly once the surface was clear. Chair feels much better now.

  22. R. Nakamura

    Fits correctly, good density

    SAN FRANCISCO, CA

    Fit is accurate for size B and the foam density feels right. Not too soft, not too firm. Very close to what I remember the chair feeling like when it was new.

  23. Sandra Osei

    Old foam was rock hard

    BOSTON, MA

    My Aeron is probably 12 years old and the front foam had turned almost completely rigid. This replacement brought softness back to the seat edge. My legs are much happier after long work days.

  24. Phil Tanaka

    Great value for $30

    CHICAGO, IL

    I was surprised something this small made such a noticeable difference. The front seat edge was digging into the back of my legs and after replacing the foam it’s comfortable again. Thirty dollars well spent.

  25. D. Reyes

    Super easy install

    AUSTIN, TX

    Peeled the old foam off, pressed the new one in. Done in about 8 minutes. Fits the size B perfectly and feels just like new.

  26. Karen Lim

    Front edge is comfortable again

    SEATTLE, WA

    The foam on the front edge of my Aeron seat had completely flattened out. My legs were pressing against bare hard plastic all day. This replacement was easy to peel and press in. Immediate difference in comfort.
