In the Roman Republic, and later the Empire, the curule seat (sella curulis, supposedly from currus, "chariot") was the chair upon which senior magistrates or promagistrates owning imperium were entitled to sit, including dictators, masters of the horse, consuls, praetors, censors, and the curule aediles. Additionally, the Flamen of Jupiter (Flamen Dialis) was also allowed to sit on a sella curulis, though this position lacked imperium. Livy writes that the three flamines maiores or high priests of the Archaic Triad of major gods were each granted the honor of the curule chair.
According to Livy the curule seat, like the Roman toga, originated in Etruria, and it has been used on surviving Etruscan monuments to identify magistrates, but much earlier stools supported on a cross-frame are known from the New Kingdom of Egypt. According to Cassius Dio, early in 44 BC a senate decree granted Julius Caesar the sella curulis everywhere except in the theatre, where his gilded chair and jeweled crown were carried in, putting him on a par with the gods. As a form of throne, the sella might be given as an honor to foreign kings recognized formally as friend (amicus) by the Roman people or senate.
The curule chair was traditionally made of or veneered with ivory, with curved legs forming a wide X; it had no back, and low arms. Although often of luxurious construction, the Roman curule was meant to be uncomfortable to sit on for long periods of time, the double symbolism being that the official was expected to carry out his public function in an efficient and timely manner, and that his office, being an office of the republic, was temporary, not perennial. The chair could be folded, and thus an easily transportable seat, originally for magisterial and promagisterial commanders in the field, developed a hieratic significance, expressed in fictive curule seats on funerary monuments, a symbol of power which was never entirely lost in post-Roman European tradition. 6th-century consular ivory diptychs of Orestes and of Constantinus each depict the consul seated on an elaborate curule seat with crossed animal legs.
Along the Silk Road the folding seat of the Eastern Roman Empire made its way to China, where in various forms including the hu chuang— the "barbarian bed"— it "transformed the dress, architecture and lifestyle of the Chinese"  In Han China the folding chair made its first literary mark in the 2nd century AD, used out-of-doors in a military rather than domestic setting, and from the way it was addressed in a poem by Yu Jianwu, written about 552
By the name name handed down you are from a foreign region
coming into [China] and being used in the capital
With legs leaning your frame adjusts by itself
With limbs slanting your body levels by itself...
it is clear the cross-framed folding seat was intended.
In Gaul the Merovingian successors to Roman power employed the curule seat as an emblem of their right to dispense justice, and their Capetian successors retained the iconic seat: the "Throne of Dagobert", of cast bronze retaining traces of its former gilding, is conserved in the Bibliothèque nationale de France. The "throne of Dagobert" is first mentioned in the 12th century, already as a treasured relic, by Abbot Suger, who claims in his Administratione, "We also restored the noble throne of the glorious King Dagobert, on which, as tradition relates, the Frankish kings sat to receive the homage of their nobles after they had assumed power. We did so in recognition of its exalted function and because of the value of the work itself." Abbot Suger added bronze upper members with foliated scrolls and a back-piece. The "Throne of Dagobert" was coarsely repaired and used for the coronation of Napoleon.
In the 15th century, a characteristic folding-chair of both Italy and Spain was made of numerous shaped cross-framed elements, joined to wooden members that rested on the floor and further made rigid with a wooden back. 19th-century dealers and collectors termed these "Dante Chairs" or "Savonarola Chairs", with disregard to the centuries intervening between the two figures. Examples of curule seats were redrawn from a 15th-century manuscript of the Roman de Renaude de Montauban and published in Henry Shaw's Specimens of Ancient Furniture (1836).
The 15th or early 16th-century curule seat that survives at York Minster, originally entirely covered with textiles, has rear members extended upwards to form a back, between which a rich textile was stretched. The cross-framed armchair, no longer actually a folding chair, continued to have regal connotations. James I of England was portrayed with such a chair, its framing entirely covered with a richly patterned silk damask textile, with decorative nailing, in Paul van Somer's portrait (illustration, left). Similar early 17th-century cross-framed seats survive at Knole, perquisites from a royal event.
The photo of actor Edwin Booth as Hamlet (illustration, right) poses him in a regal cross-framed chair, considered suitably medieval in 1870.
The form found its way into stylish but non-royal decoration in the archaeological second phase of neoclassicism in the early 19th century. An unusually early example of this revived form is provided by the large sets of richly carved and gilded pliants (folding stools) forming part of long sets with matching tabourets delivered in 1786 to the royal châteaux of Compiègne and Fontainebleau. With their Imperial Roman connotations, the backless curule seats found their way into furnishings for Napoleon, who moved some of the former royal pliants into his state bedchamber at Fontainebleau. Further examples were ordered, in the newest Empire taste: Jacob-Desmalter's seats with members in the form of carved and gilded sheathed sabres were delivered to Saint-Cloud about 1805. Cross-framed drawing-room chairs are illustrated in Thomas Sheraton's last production, The Cabinet-Maker, Upholsterer and General Artist's Encyclopaedia (1806), and in Thomas Hope's Household Furniture (1807).
With the decline of archaeological neoclassicism, the curule chair disappeared; it is not found among Biedermeier and other Late Classical furnishing schemes.
