Sofas with chaise longue

A recliner, a daybed, an ottoman, couch, half-sofa, dyscha or divan. What exactly is what? Or first of all, what is the difference between a divan and a chaise longue? A divan has an open end and backrest on the divan module itself, unlike a chaise longue sofa, which has an open end and armrests on the chaise longue part. Chaise longue means long chair in French. In short, you can say that a sofa with a chaise longue is a kind of recliner that is so long that you can put your legs up.
