Mattress Pad和Mattress Protector的区别是什么?

这是Mattress Pad的介绍
Add softness to your mattress with this extra layer of quilted polyester and cotton. Extra-long with wide anchor bands for an easy on-and-off fit. Machine wash and dry.
是不是Mattress Pad放在床垫上的东西,而不等于是床垫呢???

Mattress Protector的介绍,
Add an extra layer of protection underneath your mattress pad and egg crate pad. This super-smooth, hypo-allergenic mattress pad cover provides an antimicrobial barrier between you and the mattress. Highly recommended for asthma and allergy sufferers.

谢谢,以后会追加

Mattress Pad是指软的，薄的床垫，就像棉花，涤纶什么的，而那个Mattress Protector是指套在外面的东西，就像摊子，在垫子上面的东西那成布

按字面意思来看，那层mattress protector的作用类似于床单（将你和床垫隔开）。你可以问问学校看这层东西是什么材质的，会不会引起你的过敏症状。
