Details: Leap Plus provides the benefits and functionality of the standard Leap chair to users weighing up to 500 lbs. Thanks to LiveBack technology, the Leap chair back flexes to change shape as your back changes shape, providing stable support and encouraging unrestricted movement. And with its simple and intuitive adjustments – like separate controls for Lower Back Firmness and Upper Back Force and adjustable armrests that move in four directions – it’s easy to adjust your Leap chair to fit you comfortably for the entire day.
