Is this a Herman Miller original part, or after market?

I dont think it is original, but the quality and fit is the same as original. Fits great.

What are the dimensions of the pad?

12x4.25" It fits on the larger chair. I believe that's "c".

Does this work for the Aeron Remastered or just classic?

This lumbar only for the first generation aeron chair, can't fit the remastered, thank you!

Would this fit even though I have posturefit?

You need remove the posturefit firstly, and then can install this lumbar, only can one style lumbar, posturefit or lumbar support pad.

Super easy to put on, fit the Aaron C chair

The previous lumbar support had torn and not connected to one side of the chair. This replacement took seconds to put on. Look like an exact replica of the original part.
