Supporting your spine, Aeron PostureFit chairs give the additional support to of pelvic alignment. The design, according to the SmartFurniture website, "reduces fatigue and increases endurance by improving the natural spinal curvatures and muscle balance, whether reclining or sitting upright."
When sitting in this chair, the Pellicule material adjusts to the weight of the individual. The seating area, by reacting to the forces of the person, causes the sitter to be positioned slightly forward. This allows the pelvis to tilt forward and align, decreasing pressure on the lower back.
Supporting the pelvic alignment, the back of the chair is curved and hits around the center of your back. This pushes the body forward and keeps a straighter spine. This element works in sync with the cushion to remove compression on the lower back and keep pain away.
