Chi Machine Buying Guide: Which Chi Swing Machine to Buy
Short answer: a chi machine (also called a chi swing machine) is a small floor unit that gently rocks your ankles side to side while you lie on your back. You relax and the machine does the motion. Most people use it 5 to 15 minutes a day at home. Our two best sellers are the Daiwa Felicity Chi Swing USJ-201 ($199) and the Daiwa Felicity Vitality Swing USJ-815 ($299). Both ship free to the lower 48.

What does a chi machine do?
It moves your lower body in a smooth, side-to-side swing while you stay still. Many owners use it to unwind after work, before bed, or after long hours sitting. It is a relaxation device, not a medical device. If you have a health condition, a recent injury or you are pregnant, ask your doctor before using one.
Chi machine vs. other home massagers
- Chi machine: passive full-body swing. Best if you want to lie back and do nothing.
- Heavy-duty body massager like the Felicity Max Pro USJ-330 ($219): strong, targeted massage on the back and large muscles.
- Leg and foot massagers like the Felicity Ninja Leg 2 ($399): air compression and heat for calves and feet.
- Massage chair: the whole-body option. Start with our 2-minute chair quiz.
