Bentwood rocker

Bentwood chairs have become so much a part of our lives as to be almost invisible. In a simplified form they have been used in so many everyday places - shops, schools, private houses and public places - that it is difficult to imagine that their whole style was once a complete revolution in furniture-making. Today they are turned out in their thousands in factories all over
Signs of authenticity
1. Laminated wood, built up of alternately grained strips.
2. Generous curves with long unbroken sections curving under and over, rather than separate pieces joined at short intervals.
3. Taut panels caned on the diagonal to allow for the springiness of the chair.
4. Surface of wood smooth and silky, instantly recognizable once touched, compared with later solid bentwood.
5. Impeccable finish with sections shaped and smoothed to flow into the join.
6. Early solid birch bentwood chairs should be finely sanded and finished under black
I ebonized’ paint.
Likely restoration and repair
7. Laminated bentwood chairs and rockers which have been subject to too many changes in temperature and humidity will be ’sprung’ on curves, i.e. there will be splitting where the wood has shrunk and pulled away. It may be tacked and glued back into position but the damage is permanent and will occur again.
8. Recaned on the horizontal and vertical. The caning will break and the chair will not maintain its shape, but will eventually split from the strain.
9. Black paint stripped off. If this has been done by complete immersion in a caustic solution there may be some dissolving of the adhesives between laminations. Stripping must be done painstakingly by hand and there should be some small signs of remaining paint.
England, but their origins were elite and aesthetic.
Michael Thonet (1796-1871),
their inventor, was an Austrian who trained as a craftsman in the South German Biedermeier school of furniture-making. This was established as a reaction against French influence, in part motivated by the aspiration for a united Germany after the Napoleonic Wars, and in part aesthetic, a search for well-designed ‘bourgeois’ furniture. The parallel desire was felt in England, and was evident in the designs of J. C. Loudon and his school. Biedermeier was particularly successful with seat furniture, which was solid, well-made, elegant and, above all, comfortable. It was Michael Thonet’s search for new materials and techniques to
make chairs without ornament, carving or traditional construction that led him to experiment with the shipbuilding techniques of steaming and bending wood. His designs were first produced in laminated wood in the 1840s.
Thonet took out patents for his chair-making techniques, but when the patent ran out in the 1860s a London firm of furniture-makers, Hewlett and Company, took it up, and by the end of the century bentwood chairs were being made by many furniture-makers, particularly in High Wycombe, centre of England’s chair-making industry.
Construction and materials
Michael Thonet’s original designs were made in thin strips of wood, steamed and bent into shape and laminated together - a technique which had been known in England for about 100 years, although laminated wood had only been used for parts of furniture and not for a whole piece. Thonet’s first commission for these novel, smooth-curving designs was for the Leichtenstein Palace in Vienna, and although they were more detailed and complicated in their sinuous construction, the basic bentwood chair of today differs very little from those prototypes.
In England, the technique of steaming and bending wood had been applied to Windsor chairs for some years, using solid wood as
Variations
Bentwood chairs were particularly suitable for children, and both high chairs and small, miniature versions of the standard shape were made, particularly in the 1920s, for use in schools and nurseries.
Some early, finely designed, bentwood chairs made in England include versions of the sabre-legged S-armed chair, with the back made in a single hoop with the back legs, which are raked well back. Front legs curved forward in imitation of the line of the sabre-leg, but were round-sectioned and taper-turned. The S-curve of the arms was particularly suitable for the new bentwood technique.
Once furniture-making factories had begun to turn out bentwood chairs by the thousand, their finish and style degenerated into the ‘tearoom chairs’ of the 1920s and 1930s, being reduced to circular hoops and slightly splayed legs, whose timber was no longer carefully chosen for the correct grain, and which have since split and cracked.
opposed to laminated. The timber was generally birch, traditional wood for chair-legs because it was amenable to bending and was springy enough not to break or split. The cane seat, too, had been in production for country chairs and lightweight seat furniture ever since Sheraton had reintroduced it at the end of the eighteenth
century.
Early genuine Thonet bentwood chairs and rockers, for which the technique was particularly
suitable, were more curvaceous and elaborate, mainly due to the laminated wood which allowed more freedom than later bentwood chairs in birch, which consisted mainly of a series of hoops and standardized curves.
Reproductions
After a considerable spell of unpopularity as ‘cheap chairs there are now many extremely good reproductions of the original bentwood chair on the market, many of them originating in Taiwan and the Far East, where manufacturing is cheap and labour still skilled in traditional crafts such as caning. Their reappearance on the English scene can largely be attributed to the many well-designed small restaurants with imaginative decor, for which they were originally imported.
