The lumbar pad, positioned at the back, is adjustable, allowing for physical adjustments in both upward and downward directions. Alternatively, the posture fit support, available at an additional cost of $100, offers a more fixed support system with a side dial to increase pressure on your back. Interestingly, the majority of individuals tend to favor the lumbar pad. Moreover, there’s flexibility to upgrade to the posture fit at any time and easily attach it later on if desired.
