厚度越大越难体现弹簧支撑：护脊弹簧床垫舒适层过厚（＞8cm海绵/乳胶）会削弱弹簧分区效果，让身体先陷入软层而非被弹簧承托，追求护脊应选22-28cm总厚且弹簧层占主导的结构

Unverified缓冲效果与粘贴牢固性存在权衡：越厚越软的护角自重越大，普通背胶越容易因重力下垂脱落，厚护角建议选择自带机械固定（螺丝/绑带）或强力胶的款式84% similarUnverified胶带宽度越宽密封越可靠，但过宽会在弯曲部位（袖窿、腋下）产生僵硬感和翘边，活动部位应选窄款并做圆角处理83% similarUnverified胶带拉伸性越好（延展率高）缠绕越贴合弯角，但过度拉伸缠绕会导致回弹松脱，缠绕时保留约20-30%的拉伸余量最牢固83% similarUnverified独立袋装弹簧的支撑分区通常做成5区或7区，弹簧线径越粗（如1.8-2.0mm）支撑越硬，肩部区常用细线径弹簧以实现软化承托83% similarUnverified伸缩式（可调节宽度）隔板的两端支撑杆是承重薄弱点，实际有效承重约为标称值的60%，且伸缩越长下垂越明显；宽度＞80cm的隔层建议选整块固定隔板而非伸缩杆式83% similar
