The Teeter F is fairly lightweight at 62 lbs. It is 45 inches long, 28 inches wide and 58 inches long. The table is adjustable for individuals of different heights. You manually control the rotation of the table by redistributing your weight -- it works similar to a teeter totter. You can set the hinge to limit the responsiveness of the table. If you are a beginner, set the roller hinge for only partial inversion. Advanced users can set the hinge for full inversion. The F can be locked at a full 90 degree inversion.
