Daiwa Felicity USJ-815 Vitality Swing
The Daiwa Felicity USJ-815 Vitality Swing is an upgraded passive aerobic chi swing machine that promotes circulation through a smooth wave-like motion originating at the ankles and traveling up through the legs and spine. Its 40W motor — more than double the power of the entry-level USJ-201 — delivers a stronger, more consistent oscillation with variable speed control. A remote control and 15-minute auto-timer make it simple to use without changing position.

Frequently Asked Questions
What is the difference between the USJ-201 and the USJ-815?
The USJ-201 runs on a 15W motor with fixed speed. The USJ-815 uses a 40W motor with variable speed control, delivering a stronger and more adjustable oscillation. The USJ-815 is the better choice for users who want more intensity or prefer to customize the swing speed.
How does the chi swing motion benefit circulation?
The wave-like oscillation creates a lateral swinging motion at the ankles that propagates up through the legs and spine, stimulating the lymphatic system and venous circulation in the lower extremities — areas where blood can pool during prolonged sitting.
