Primarily a compound noun (back + rest). Denotes a functional part rather than an object itself. Often implies adjustability or specific design for comfort.
Dialectal Variation
British vs American Usage
Differences
No major lexical differences. Both use 'backrest'. In British English, 'headrest' and 'backrest' are often distinct terms; in US English, they may be collectively referred to as 'seat backs' in some automotive contexts.
Connotations
Neutral in both. Slightly more technical/descriptive than everyday.
Frequency
Equally common in both varieties in technical/manufacturing contexts. Slightly less frequent in everyday UK speech, where 'the back of the chair' might be used informally.

- Do not confuse with 'подголовник' (headrest).
Common Mistakes
- Using 'back rest' as two words in standard modern English (should be one word or hyphenated: backrest/back-rest).
