Is 'back rest' one word or two?

Both 'backrest' (one word) and 'back rest' (two words) are correct. 'Backrest' is slightly more common in modern usage, but technical documents may use the two-word form for clarity.

What's the difference between a 'back rest' and 'lumbar support'?

A 'back rest' refers to the entire supportive structure for the back. 'Lumbar support' is a specific part of a back rest designed to support the lower back curve. All lumbar supports are part of a back rest, but not all back rests have dedicated lumbar support.

Can 'back rest' be used as a verb?

No, it is not a standard verb. It is primarily a noun. Using it as a verb (e.g., 'to back-rest a chair') is non-standard and rare.

Is this a common word for English learners?

It is a B2-level word. Learners encounter it when discussing furniture, travel, cars, or health/ergonomics. It's useful for specific descriptive contexts but not a high-frequency everyday word.
