The following three points provide relevant judgment basis.
1, noise: whether the operation is silent or not is an important indicator, and noise is related to power. The power of 150W is the national standard. The sound of this massage chair must be quiet, and the greater the power, the louder the noise. A massage chair with a power higher than 200W must have a rough mechanical structure and poor quality. Pay special attention to buying for the elderly!
2, movement: massage chairs with high-quality movements are generally more expensive, but not necessarily high-priced shopping malls are good movements. The movement of massage chair is divided into 1D movement, 2D movement, extended movement and 3D precision movement.
1D movement is usually used for cushions and thousand yuan massage chairs. Single rotation (kneading) pulping;
The main methods of 2D exercise are kneading, tapping, shiatsu and kneading-tapping synchronization. Disadvantages: light intensity, cervical massage is not in place;
The extension of the action hand increases the manipulator, which makes up for some places where massage is not in place, but it also leads to excessive position force in some places;
3D precise sports massage is more in-depth, realizing up, down, left and right front and back massage to prevent deformation and displacement.
The 3D precision movement has high cost, and the trouble-free running time is more than 3,600 hours. 1D movement has low cost and trouble-free running time of 600 hours. In other words, the former will not have problems for at least five years, while the latter may have problems for one year. Friends who pay attention to function must know in advance.
3, material: massage chairs generally do not leak electricity, first of all, the material must be insulated massage special leather, even if it leaks electricity, it will not cause life damage, because at present, the driving motors of mainstream massage chairs are all DC 24V, (the human safe voltage is not higher than 36V). Ordinary leather is cheap, and its life span is 1-3 years. Leather on the head and back is the most vulnerable. The feel is too soft or too hard, and the skin is very thin, so it will break when pinched by hand. If it is a gift for a friend, PU massage leather should be the first choice in material, which will be thicker and more upscale. The other piece is wrapped with sponge, and the inferior machine materials are generally not wrapped with sponge or wrapped with thin sponge. If the experience is not good, it is easy to break and cause safety hazards.
