The Louis Chair was designed in the Rococo era, coming from the combination of the French words rocaille (stone) and coquille(shell).
The luxury of rich upholstery, cabriole legs and exquisite hand crafted designs made these a very popular for Royalty. Practically the Louis Chair was used as a luxury chair in summer then in winter they would attach the foot stool to make a Chaise to rest their legs and nestle under a warm blanket.
A chaise longue (shayz long, "long chair") is an upholstered sofa in the shape of a chair that is long enough to support the legs.The modern chaise lounge was first popularized in 16th century France. The Style and Sophistication is just as popular in our modern homes today.
