chaise longue
Pronunciation: /ˌʃeɪz ˈlɒŋg/
(North American also chaise lounge)

Origin:
early 19th century: French, literally 'long chair'

The unfamiliar-looking spellinɡ of chaise longue (‘long chair’ in French) has led many people to interpret it as the more English chaise lounge. This is regarded as an error in British English but is a common and accepted variant in US English.
