Selecting the right massage equipment requires a balance between mechanical durability, ergonomic design, and safety certifications. Buyers should prioritize products with brushless motors for longevity and noise reduction (ideally <45dB). For massage chairs, look for 3D or 4D massage hands that simulate human touch, and ensure the track is an SL-track design (120-135cm) to cover from the neck to the hamstrings. Always verify the outer material, such as high-grade hydrolysis-resistant PU leather, which should withstand at least 5 years of regular use without peeling.
