F2 System

An underlying theme of BASI Systems Pilates equipment is to perpetually strive toward achieving a perfect balance of form and function (F2). This has become known as the F2 System.

Developed by Rael Isacowitz, the trailblazing F2 System is a true innovation for Pilates movement, offering unprecedented versatility and precision in spring angle and resistance settings. Springs can be attached to different points on the Reformer, Cadillac, Ladder Barrel, Wunda Chair, and Spine Corrector.


Multiple F2 Systems can be used simultaneously to inspire exciting new repertoire possibilities. The levers also serve as handles to support wrists and shoulders in an optimal position for weight-bearing exercises.
