Pillowtop vs Euro Top
Both terms describe how an upper comfort section is integrated into the mattress. They do not specify the comfort material itself.
A traditional pillowtop often has a visibly separate, gusseted appearance. A Euro-top is typically integrated more flush with the mattress edges. Construction varies by manufacturer, so inspect the layer diagram instead of choosing by the label alone.
