The Wunda Chair essentially looks like a box with one side exposed, which enables access to the resistance springs. The “seat”, a smaller base of support, can expose more weakness, which is often why this beautiful apparatus is not favoured as much as the Reformer. However, similarly to the Reformer, its use of numerous resistance options enables each exercise to have a different tension; sometimes a lighter spring is more difficult than a heavier one – the springs can be adjusted to suit your needs. The pedal itself is attached to the springs and moves in an upward and downward motion. Whether controlled by your feet or hands, the spring will challenge or assist you from exercise to exercise. The Wunda Chair’s versatility is endless; sitting down to perform leg and footwork, completely inverting yourself for abdominals, laying on your side or flipping onto your front, this truly is a wunda-ful chair.
