When purchasing a shiatsu massage chair, the company that stands behind it is also important. You first should choose a chair to fit your needs. But do not forget, the company tmust service it when issues arise. Customer service is critical when service is needed. Manufacturers vary and how they support the product also varies. Bigger is not always better. Our experience is relatively short times to resolve issue, which is important. They have a call center located in the US for us English speakers which is open 24/7 for warranty issues.
Warranties that are longer and more comprehensive protects the customer and provides additional value. Whereas, shorter and less coverage gives the customer less confidence in the manufacturer. One would think Sanyo would have one a superior warranty. However, compared to the competition, Sanyo's warranty is just plain weak. What is Sanyo's warranty? 3 years on the roller mechanism, 1 year labor, 1 year parts. Sanyo did step up for in-home service for the first year. When your paying a $5,000 price tage, the warranty should be much stronger.
What about the HEC-DR7700K Zero Gravity shiatsu massage chair? Zero gravity is a position where the pressure from your body is removed from your spine and evenly distributed across your back. Officially, the chair must lean back far enough so your knees are above your heart. This is a nice feature in the chair. It's a nice position to relax before and after a massage.
The HEC-DR7700K has a built in Stiffness Detection Sensor. The stiffness detection sensor is based on lie detection technology and detects stress points throughout your back. The Stiffness Detection Sensor gauges fatigue by monitoring changes in your perspiration and pulse rate. The massage is adjusted to pinpoint higher areas of stress.
The Physical Shape Sensor adjusts the massage rollers to your body shape. The rollers adjust to your body shifts during the course of the massage. It is an interesting feature for the more squeamish among us. Personally, I find I adjust my position to the fixed rollers when I want to hit a particular part of my back.
Sanyo's has an exclusive GK Roller Technology. The GK rollers have the capability to "reach out" of the massage chair. The reaching out is a great function for the neck and shoulders. Sanyo has added an extra thumb as part of the roller system. It is great to see 3 dimensional massage functions be incorporated to massage your neck and shoulders. These rollers extend out to give an extra dimension of massage sensation. Congratulations Sanyo on breaking into the 3 dimension robotic massage chair!
