- Extendable footrest feature 10/10: Loved the feature; it just creates so much convenience. I’m about 5’7” and could fully stretch my feet out, without compromising comfort.
- Computerized Body Scan 10/10: This targeted approach enhanced my overall massage experience. It almost felt like a skilled masseuse relieving tight knots and fatigue from my body.
- Auto programs 9/10: There wasn’t such an issue with the programs, everyone performed well on their part. However, I wished for some chiropractic massage techniques like SV-Chiro, as offered by other alternate massage chairs.
- Controlling system 8/10: It’s a good thing to have two alternate ways to control a device. However, I got a bit confused when personalizing the message. The manual control was somewhat uncomfortable and to be honest, I didn’t use it as much as I used the wireless remote.

This positioning is accredited as the optimal state in which our body tends to work at its best, and here’s why: Increased intensity of massage as your back is virtually supported by the backrest. At the same, reduced vertical stress on the spine because of elevating the lumbar region and elevating the legs above the heart helps promote blood circulation. In the second stage, your body experiences a greater recline and, thus, greater relaxation.

The purpose of this second remote is to ensure users can make adjustments without stretching or straining from their reclined position.
Heat Therapy

However, it’s advised not to use the heat therapy for more than 30 minutes daily due to safety and health considerations. Always make sure to adhere to the guidelines for a safe and comfortable experience.
