La pieza original que tenía la silla Aeron, duró 15 años, y esta pieza no duró ni 7 días!!! ### ⭐⭐⭐⭐⭐ Works as advertised. Lubricate as needed. *by on Reviewed in the United States 14 August 2025* Provides a moderate level of adjustable lumbar support that is a good option on Amazon for the Aeron classic chairs. You slip the piece into the grooves on the side of the chair and adjust it to the height you prefer. The other reviews mentioned the lumbar pad was popping out under use. To mitigate this issue, lubricate and clean the grooves as well as the C hook of the lumbar pad to allow the hook to move freely, otherwise it will eventually pop out and cause damage to the sides. ### ⭐⭐⭐⭐⭐ Works *by on Reviewed in Germany 2 May 2026* Fits and works as original ## Frequently Bought Together - Lumbar Support Pad Replacement for Herman Miller Classic Aeron Chair - Size B: Medium,Black - Seat Pad Foam Insert Replacement for Herman Miller Classic Aeron Office Chair A B C Size (Black, A/B) - Vinyl Arm Pads Caps for Herman Miller Classic Aeron Chair Graphite Black --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.ar/products/411837176-ketofa-lumbar-support-pad-replacement-for-herman-miller-classic-aeron](https://www.desertcart.com.ar/products/411837176-ketofa-lumbar-support-pad-replacement-for-herman-miller-classic-aeron) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-09-27*
