Formal or literary term for going to bed; similar to 就寝 but rarer and more bookish. Often used in written descriptions or formal contexts.

就寝 is the common formal word for going to bed; 就床 is rarer and more literary, with a similar meaning.
Compound of 就 (しゅう, 'to take up, to proceed to') and 床 (しょう, 'bed'). The exact historical derivation is uncertain, but the word follows a classical Chinese pattern for formal compounds.
