Unverified堆叠稳定性依赖箱盖凹槽与箱底凸台的咬合设计，平顶无咬合结构的箱子叠放时横向易滑落，容积越大重心越高的箱子堆叠风险越大88% similarUnverified堆叠稳定性与开合便利性冲突：纯堆叠箱省空间但取底层需整摞搬开；带前开门的堆叠箱可直接抽取但承重和稳定性下降、堆高不宜超过3层84% similarUnverified需要叠放堆叠的收纳盒，认准盒盖与盒底有卡扣式互锁凹槽设计，单纯平顶叠放在搬动或震动时易滑落，负重叠放时选PP材质壁厚≥2mm的款式防止形变塌陷84% similarUnverified叠放稳定性看两点：箱盖是否有凹槽卡位设计+壁厚≥2mm，无卡位的平盖叠放3层以上易滑塌，卡位设计可安全叠5层左右83% similarUnverified多个收纳箱叠放时，箱盖上表面需有下凹嵌位设计（可承接上层箱体底部脚位），无嵌位的平顶箱叠放高度超过2层易侧滑；带四角加固脚的箱体叠放稳定性显著更高82% similar
