Osaki Ai Vivo (Duo) 4D + 2D

After using it daily for 15–30 minutes, I noticed a huge difference in stress levels, muscle tension, and sleep quality. It helps relieve back pain and fatigue, especially after long workdays or gym sessions.

This chair is worth every penny! It is amazing and hands down beats the best jacuzzi or dry sauna I have ever tried. I was very skeptical at first, well consider me a lover now..I highly recommend for arthritis issues as well..
