Proper Lumbar Support - The Three-Fold Effect

The basis of all lumbar support systems is to achieve correct seating position. To attain optimum seating position, the lumbar seating system must provide support to the pelvis, lumbar vertebrae and upper body. The support of these areas is commonly referred to as the "Three-Fold Effect." Effective support of these areas will enable lasting seating comfort after the initial adjustment.

The Three-Fold Effect

1. Support of the Pelvis (to prevent it from rotating backwards)
2. Support of Lumbar Vertebrae
3. Vertical Support of Upper Body
