La présente invention concerne un canapé qui est pourvu d'un dossier et d'un siège qui coulisse vers l'avant et vers l'arrière. Le siège est pourvu d'une partie de surface de siège et d'une partie saillante qui fait saillie vers l'arrière depuis la partie de surface de siège, et le dossier et la partie en saillie sont reliés par un élément de liaison élastique. Lorsque le siège est dans une position tirée vers l'arrière, la partie saillante est rangée dans un espace interne arrière, qui est formé à l'intérieur du dossier ; lorsque le siège coulisse vers l'avant, la partie saillante est retirée de l'espace interne arrière. Grâce à cette invention, au moyen de la partie saillante retirée de l'espace interne arrière en tant que partie de la partie de surface de siège, il est possible d'augmenter la longueur du siège dans la direction de la profondeur sans rendre le dossier plus épais.
