本发明所述海绵的原材料A中各种成分及作用如下：
所述聚醚多元醇采用的是聚醚多元醇330N，是海绵的主原料之一，其作用是使海绵成品起高回弹；
所述高活性聚醚采用的是高活性聚醚3630，是海绵的主原料之一，其作用是海绵成型过程中起高回弹软泡，自结皮软泡；
所述三乙烯二胺采用的是三乙烯二胺A33，其在海绵成型过程，前期起快速发泡和30-50％凝胶作用，后期起加快固化作用；
所述延迟胺催化剂采用的是延迟胺催化剂A300作用，其在海绵成型过程中起减慢粘度增加速度的作用，让发泡原料均匀分布模腔；
所述三乙醇铵在海绵的成型过程起交联剂作用，使海绵成型后变软，增大发泡时间也变短，品泡孔直径随着其含量增加而变小，表观密度、热导率、压缩强度、拉伸强度和弯曲强度增大，断裂伸长率减小；
所述硅油采用硅油L5333，其在海绵成型过程中调节气孔大小的作用；
所述二甲基乙醇胺在海绵成型过程中起平衡催化剂作用，也起到增加海绵强度的作用；
所述开孔剂作用在海绵成型过程中起到提高成型开孔率作用，减少胀气，从而解决闭孔容易使产品成型后收缩的问题；
所述抗菌剂的作用是：海绵成型并用作椅座垫后，抗菌剂能抑制椅背棉表面及制品孔隙不会隐藏或进入脏污尘埃，从而起到抑菌、杀菌效果，即利用缓释技术，使产品具有持久的抗菌效果，可对细菌进行高效广谱的杀灭和去除；
所述抗静电剂的作用是：海绵成型并用作椅座垫后，抗静电剂分散到座垫海绵的表层，由于座套及儿童衣服均为纤维面料，当产生静电时，抗静电剂从座垫海绵的表层起到防静电作用。
经过相关测，本发明所述海绵可抑菌抗菌的种类有8种，包括：黑曲霉(Aspergillusniger)、土曲霉(AspergilluSterreus)、出芽短梗霉(Aureobasidiumpullulans)、宛氏拟青霉(Paceilomycescarioti)、绳状青霉(Penicilliumfunicolosum)、绿色木霉(Trichodeimaviride)、绿青霉(Penicilliumochrochloron)，柄帚霉(Trichodermaviride)等，防霉等级达3级。被试样品在结果判定时，放大50倍观察不到霉菌生长。
经过相关测，本发明所述海绵在防静电方面可实现：
1、导电/防静电性能不受环境湿度影响；
2、导电/防静电性能永久；
3、体积电阻和表面电阻值103-109Ω。
经过相关测，采用本发明所述海绵制成的椅座垫海棉成品软硬度在50-55度之间，符合支撑儿童体重要求。
以上仅为本发明的实施方式，并非因此限制另一方面通过本发明的专利范围，凡是利用本发明说明书内容所作的等效变化，直接或间接运用在其他相关的技术领域，均同理在本发明的专利保护范围之内。
