ABSTRACT:
A safer, more user-friendly spring-balance single-rider teeter-totter includes manual adjustments for both the vertical position of the spring, which adjusts the rest height of the seat, and the horizontal position of the spring from the pivot, which adjusts the counterbalance resistance. A safety cover may be provided for the spring or other counterbalance mechanism.
