Myth Buster: More Motors Is Better in a Massage Chair

The massage chair industry has a few myths that have been sustained over a number of years. One particularly interesting one is the number of motors in a massage chair. The myth claims that the more motors in the shiatsu massage chair the better. Certainly, an increase in the number of motors can enable more functions. Practical reality suggests that more motors means more cost and more real estate and weight of the massage chair. This myth will be explored in this article.

The more motors the better the chair myth is going to be put to the myth buster test. Obviously, having more motors enables more massage options to be possible. Motors are not cheap, in fact they are expensive. Immediately, there is a quality versus quantity tradeoff. Having 18 motors versus 3 motors would make the cost of the 18 motor chair skyrocket, if they use the same quality motor. First concern is the quality level of motors in a massage chair with 18 motors.

The motors used in a massage chair must be allocated space within the chair. If more motors are used, then more mechanism must be installed around each motor to drive whatever massage function. More and more real estate in the massage chair is used to accommodate additional motors. Motors are fairly heavy, weighing 2 lbs to 5 lbs each. If the massage chair has 18 motors at 5 lbs each, that is 90 lbs just in motors. Adding additional motors increases the weight of the chair and takes up valuable real estate within the chair.

How are high end luxury massage chairs designed with motors? Most manufacturers use 3 high quality motors. One for the kneading massage, one for the tapping massage and the third motor for moving the roller unit up and down. Software synchronizes the movements of the motors and running the tapping and kneading motors together produces the shiatsu massage.

There is a 5 motor design where the kneading and tapping use two motors each. This is done by having a motor on both the left and right side rollers for both the kneading and tapping. Having 2 motors for kneading splits the duty and should lead to longer motor life. Did it make any difference in the massage capabilities? There was no noticeable difference. Is more better?

Some massage chair companies started this fad and some how it caught on and became perpertuated into myth. We still see massage chair companies hyping that they have 12 or 15 motors. It is obvious that these motors cannot all drive the massage mechanisms. These companies think that if it moves, we can count it as a motor. Having motors is not enough, what do they actually do? This is a myth built on hype and unsubstantiated facts. Why would someone want an overly complex chair with low quality motors? Simple is the elegant solution.
