Daiwa Felicity Chi Swing Machine — 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, and padded ankle cradles provide comfortable support throughout each session.

Frequently Asked Questions

What is the difference between the USJ-201 and the USJ-815?
The USJ-201 runs on a 15W motor with a 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 to their comfort level.

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. This passive movement stimulates the lymphatic system and venous circulation in the lower extremities — areas where blood can pool during prolonged sitting. Regular use can help reduce leg heaviness and fatigue associated with sedentary work.
