## Questions & Answers

**Q: How do I determine whether my Aeron chair needs a size A, B, or C lumbar support pad? 
My chair's lumbar pad has 17 grooves and is about 11-1/4" between attachment points on the rear of the chair.**
A: The A, B, or C size of your chair can be determined by rubbing your finger along the inside frame, rear, of your seat: between the shoulders and on the rear side of the chair where the frame arches away from the mesh. There are raised dots there. One raised dot = A size, two raised dots = B size. 3 raised dots (in the form of a triangle) = C size.

**Q: Is there a way to check the sizes of the A/B/C/D . Unfortunately I can't find where its indicated in my broken one to replace it?**
A: The size you need to know is the size of the chair, not the back support. Open the attached link to see two ways to tell what the size of your aeron chair is: http://www.ehow.com/how_8093458_can-tell-size-aeron-chair.html

**Q: Does anyone know what size (i.e. a, b, or c) a 12.5" lumbar is? it fits a b chair but i have to bend it and force it into place. that doesn't feel right.**
A: Hello - Wendy from Office Designs here - The 12.5" lumbar is made to fit a size C chair.

**Q: Is this herman miller genuine part #133760 for aeron classic type b?**
A: It came in a herman miller box not sure if the part number but it fits a size b chair.
