One of the features that truly sets any Teeter Hang Ups inversion table apart from other brands is the precision balancing. This is in no small part due to what we call “roller hinges,” the parts that connect the table bed to the A-frame base. The roller hinges are stronger and last longer than any other on the market (backed by these engineer tests), plus the roller bearings that rotate the bed are coated with a special material that ensures smooth, quiet rotation. The three hole settings in each roller hinge allow you to adjust the inversion table’s responsiveness for your body type and are precisely calibrated to allow effortless rotation control with subtle arm movements -key to ensuring a relaxing, effective inversion experience with your Teeter inversion table.
The below video is an excerpt from a Teeter instructional DVD, explaining more about how the roller hinge settings work:
