Definition of "divan"

Startled at such an unaccountable event, they sat in close divan; and concluding that the case was in all respects unnatural and prodigious, desired that a messenger might be immediately dispatched for some male practitioner in the art of midwifery.

1751, [Tobias] Smollett, The Adventures of Peregrine Pickle […], volumes (please specify |volume=I to IV), London: Harrison and Co., […]

As I passed, I called at the mad-house; where I found Mac Fane and the scowling keeper in high divan.

1792, Thomas Holcroft, Anna St. Ives, vol. VII, letter 118

Eurydice pointed to the cupboard, and sat down on the low divan with folded hands, and looked at the floor.

1932, Maurice Baring, chapter 20, in Friday's Business‎

These are delightful places, and must be preferred to the cigar shops, if you can afford the extra for coffee, &c. Never sit in a divan, for as these establishments are in imitation of foreign customs, so you should imitate the manners of foreigners, and be as unlike an Englishman as you can; you should therefore lie at full-length on the couches, or "loll" about in some graceful attitude. Should your time be entirely your own, you may remain in the divan the whole day, provided you play at chess; and should you be passionately fond of smoking, you can have smoke at breakfast—smoke at luncheon—smoke at dinner—smoke at tea—smoke at supper

The cigar divans of the metropolis are essentially coffee-rooms, but they are of a distingué character, are more expensive in their charges, and more studied, elegant, and luxurious in their appointments and conveniences. […] They are elegantly furnished and appointed, with sofas, or cushioned chairs, numerous handsome tables, and chess and draft-boards. The whole of the London newspapers, and many of the provincial ones, are taken in; as are all the magazines and other periodicals; together with sundry of the French, Italian, and colonial journals. The freedom of the room is obtained by the liquidation of less than a shilling, which includes coffee of the best description, and cigars.

[H]e asked her if there were any place near where he could get a cup of coffee. Though she did keep a shell-fish supper-house, she was very civil, and directed him to the cigar divan on the other side of the street. Mr. Harding had not a much correcter notion of a cigar divan than he had of a London dinner-house, but he was desperately in want of rest, and went as he was directed.
