Important examples of foam in TOEIC

Vocabulary examples from the TOEIC test

In TOEIC vocabulary questions, foam often refers to materials used in products like mattresses or packaging.

▪The foam in the mattress is very soft.
▪The bubbles in the mattress are very soft.

Example of a confusing word: form (shape or structure)

▪The form in the mattress is very soft.
▪The shape of the mattress is very soft.
"Foam" refers to a soft, lightweight material often used in mattresses and packaging for cushioning. It is a noun that describes the material itself. In contrast, "form" refers to the shape or structure of something and is not used to describe the material composition of a mattress. Saying "the form in the mattress is very soft" is grammatically incorrect because "form" does not describe material properties. Therefore, "foam" is the correct choice here.

Grammar examples from the TOEIC test

Foam is usually used as a noun, and questions may ask about its material properties in TOEIC.

▪Foam is used to make the packaging.
▪Bubbles are used to make the packaging.
