UnverifiedTPE材质密度决定耐用性，双层高密度TPE（重量约1.2-1.5kg/5mm）比单层廉价款抗回弹、不易压出永久性凹坑，掂重量可初步判断品质93% similarUnverifiedTPE材质密度≥45kg/m³才有足够回弹和支撑，低密度TPE长期使用会永久性塌陷凹坑；密度过低的垫子重量往往低于1kg，可作为间接判断依据89% similarUnverifiedTPE材质密度≥180kg/m³且回弹率高的垫子不易留手肘/膝盖压痕，密度低于此值的TPE垫长期按压会永久凹陷，寿命通常不足1年84% similarUnverified高阻力档（宽度≥2.5英寸）在折叠收纳时体积较大且不易卷紧，便携性不如TPE材质带或细窄档位带78% similarUnverifiedNBR材质密度较低，10mm厚度卷起后体积较大且较重，便携性不如薄款TPE垫75% similar
