Ottoman is a widthways-ribbed textile with pronounced, raised 'ribs' along its wale and course.
Ottoman may be knitted or woven, and produces a stiff, heavyweight fabric; knitted Ottoman features a likewise widthways rib structure.
The rib lines in an Ottoman knit may vary in size from thin to coarse by adjusting yarn count and gauge.
[2] Like other woven corded fabrics - where the wale and course are unevenly matched in weight to create a ribbed effect - Ottoman has a tendency to 'slip' at seams, wherein the yarns of the weave pull apart but do not break.
[citation needed] Ottoman was typically made of silk historically, though in the present day, is woven or knitted using cotton or synthetic fibre yarns, including artificial silk yarns such as rayon and polyester.
