noun
low bench
Archaic term for a low bench or seat; not used in modern Japanese outside historical contexts.
古い文献に「床子」という低い腰掛けの記述がある。
In old documents, there is a description of a low seat called 床子.
The exact derivation is uncertain; the kanji 床 (floor/bed) and 子 (child/small thing) suggest a small floor-level seat.
