Herman Miller Aeron review
This person provides detailed information about the PostureFit SL system specifically. They explain it has two separate adjustments: one for the lower lumbar pad and one for the sacral support at the base of the spine. They note that both need to be properly adjusted and that the sacral support is particularly important for preventing the hips from sliding forward. They share that many people adjust the lumbar but ignore the sacral portion, which undermines the system's effectiveness.
Pros
- PostureFit SL has separate lumbar and sacral adjustments for comprehensive support
- Sacral support particularly effective at preventing hip sliding
- Two-part system provides thorough lower back and pelvic support
Cons
- Many users don't adjust sacral portion properly
- Two adjustments can be confusing
- Easy to overlook sacral component
