PostureFit represents a major ergonomic breakthrough in seating that delivers custom-fitted support where it's needed most: in the lower-back area below the beltline, where the spine meets the pelvis. Available as an option on the Aeron chair, PostureFit is the next-generation, research-driven ergonomic solution that supports a healthful posture and significantly improves lower-back comfort in a work chair.

How PostureFit works PostureFit provides custom-fitted support by filling the void that exists between your lower back and the back of your chair. By filling this void, PostureFit supports the natural forward tilt of your pelvis to promote the alignment of your spine. This enables you to sustain a healthier posture and, as a result, to experience a greater degree of long-term comfort while you work.

Why PostureFit works
It works because the position of the pelvis determines spinal alignment. Rotating the pelvis forward restores natural spinal alignment—and that's exactly what PostureFit does.
