1. Quality: Whether the operation is silent is an important indicator. A good massage chair must have a quiet sound, and a noisy massage chair must have a rough mechanical structure and poor quality. Don't doubt this.
2. Movement: Massage chairs with high-quality movements are generally more expensive, but not necessarily high-priced ones are good movements. The cost of the all-metal movement is relatively high, with more than 3,600 hours of trouble-free operation, and the cost of the plastic movement is lower, with 600 hours of trouble-free operation. That is to say, the former will not cause problems for at least five years, while the latter may cause problems for one year.
3. Computer control: computer control is not a color light-emitting controller. Computer control is a program that simulates a massage expert is input in advance, and it can automatically detect each human body shape, and then calculate a set of time specific people The massage plan makes people feel precise and thorough.
4. Itinerary: Itinerary refers to the range of walking up and down for the massage machine on the back of the massage chair, from the top to the back of the head to the tail vertebra. A wide massage range is better than a small range. The small range must be to save costs, because the former requires a high-rigidity lifting mechanism, and the latter uses general materials.
