Herman Miller Aeron review
The commenter asks whether the poster is using the PostureFit SL or the adjustable lumbar support, as these are different systems with different adjustment methods. They note this distinction is important for providing accurate advice about how to adjust the lumbar support properly. They explain that PostureFit SL has a pad that supports the sacral area as well as lumbar, while the adjustable lumbar is a simpler system focused only on the lower back curve.
Pros
- PostureFit SL provides sacral and lumbar support
- Different lumbar systems available for different needs
Cons
- Different systems can cause confusion about adjustment methods
