What is the difference between a chaise longue and a chaise lounge?

There is no difference between a chaise longue and a chaise lounge. The chaise longue is an upholstered piece of furniture that was made popular in France in the early 16th century. This low reclining seat, a “long chair” in English, boasts an elongated form and low back that extends about half the length of the furnishing, affording the welcome opportunity for a sitter to put their feet up and relax. (In the United States, the term is frequently spelled “chaise lounge.”) So, how do you pronounce chaise longue? It sounds like “shayz lawng,” but limiting it to shayz is perfectly acceptable in the States. On 1stDibs, shop a collection of chaise lounges on 1stDibs.
