There is a massage chair myth that has been permeated through time about the number of motors. This myth claims that the more motors contained in the massage chair, the better the massage chair. At the height of this myth, companies were claiming to have more and more motors in their massage chairs. The thought being that with more motors, the massage is greatly enhanced. Claims were made to have a massage chair with 6, 8 and even 18 motors. Of course, having more motors could enable more varied movements in the shiatsu massage chairs, but is this actually true?
This myth is going to be challenged in this article to reveal the real truth about the more motors the better the chair myth. First, one should examine the tradeoff of quantity versus quality. If a massage chair has 3 motors versus 18 motors, what is the quality level of the motors in the massage chair? Obviously, motors, not being cheap, mean that as the number of motors is increased, the cost of the chair must increase assuming the quality level is equal. However, as more motors are added, the lower priced motors (i.e. lower quality motors) will be used.
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 is the quality of massage with more or less motors? High end luxury massage chairs generally have 3 high quality motors to power the back massage rollers. There are individual motors to run the kneading massage and to run the tapping massage. The third motor drives the roller unit up and down the chair back. The tapping and kneading motors can be run simultaneously for the shiatsu massage.
If you examine the top of the line massage chairs, most use 1 motor to move the rollers up and down the chair back and 2 motors are used for the kneading and for the tapping. If the design runs each left and right roller independent, then this is done with 5 motors. The motors in this case do not provide any further massage capabilities, but will put less wear and tear on the motors, since their duties are split. Again, neat design, but no real improvement in the actual massage delivered.
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.
