Unverified厚度越大缓冲越好但收纳越困难：3cm以上XPE整张垫无法折叠只能卷收占空间，折叠垫（如1cm×4折叠）便携但折缝处厚度不均且易藏污89% similarUnverified厚度与收纳便利性矛盾：加厚双面垫（1.5-2cm）缓冲好但笨重难折叠收纳；折叠式XPE垫轻便可竖立收纳但厚度多在1cm左右89% similarUnverified拼接式泡沫地垫单块厚度建议1.5-2cm，学步期可选2cm以上缓冲摔倒冲击；整体式卷材地垫（XPE）厚度1.5-2cm即可，因无拼缝抗冲击更均匀83% similarUnverified折叠后厚度是核心便携指标：软布框架式可压缩至5-8cm平板状适合后备箱收纳，而硬质对折式折叠后仍有20-30cm厚度，仅节省高度不节省占地83% similarUnverified折叠款收纳后厚度＜8cm可平放后备箱侧壁不占空间；硬底折叠款折后仍有3-5cm硬板厚度，收纳率不如纯布款但展开更稳固81% similar
