A prefix is a type of affix that is added to the beginning of a base word or root to modify its meaning. Prefixes can change the meaning of the word in various ways, such as indicating negation, repetition, or degree. For example, the prefix "un-" can be added to the word "happy" to form "unhappy", which means not happy. Other examples include "redo", where the prefix "re-" indicates doing something again, and "preview", where "pre-" means before. Prefixes are important in word formation, allowing for the creation of new words and the expansion of vocabulary in many languages.

A mattress is a large, flat piece of cushioning material designed to support the body while sleeping. It is typically filled with materials such as foam, innerspring coils, or a combination of both, and is covered in fabric or another soft material. Mattresses come in different sizes, such as twin, full, queen, and king, to fit various bed frames. The comfort level of a mattress can vary, with options ranging from firm to soft, depending on the type of filling and construction. Mattresses are essential for providing a comfortable and supportive sleep surface.
