Two installation tips

• Knob on the right. Mount the adjustment knob on the same side as the height lever so the cable routes correctly.
• Turn the knob to a triangle. Rotate it until one point faces straight up. That leaves room to insert and tighten the mounting screw.

The installation video further down covers cable routing and knob alignment step by step.

PostureFit or lumbar pad?

If your lower back tires and you catch yourself rounding into a C-shape by the afternoon, the pad is probably supporting too high. PostureFit-style support starts at the sacrum, so the rest of your spine stacks up naturally without you having to think about it.
