CHAIR "FAMILY TREE"

It is known that it long since served... sign of a rank and dignity of the owner. In many African tribes only leaders could sit on a chair which was decorated with precious sinks, a carving,
motley beads...
By the way, inventors of a chair - seats - also reckon with a back Africans, to be exact, Egyptians. They thought up also armrests - for thrones of the governors.
And before people sat at best on benches and stools, and a thicket - on skins of animals, stubs or stones.
But it is necessary to tell, not only in Africa many centuries chairs and chairs were a symbol of a privileged position. Not without reason the English word "chairman" - the chairman - is literally translated as "the person of a chair".
Each lord in the British parliament had own chair with a folding board on a lock that nobody else could not attempt upon its place.
In Western Europe the XVI-XVIII centuries were accepted special rules of etiquette - who and where sits.
During receptions on soft chairs only members of the royal families sat. The nobility accommodated on stools.
For less well-born court brought folding seats. The others stood.
However, prestige prestige, and it was not so convenient to sit during that time on chairs. Try remain sitting at least half an hour on the Spanish chair of an era of baroque - rigid, an inconvenient form, though decorated with an elaborate carving.
Eventually the chair was improved. The St. Petersburg salons of the 1840th years were fashionable to be arranged with chairs on castors, on screws - to lift and lower seats, with backs and without...
And in the XX century to a chair there were miracles at all.
At the beginning of 1960 - ykh years the Swedish doctor Bent Akerblum, long time watching poses of the people sitting on chairs drew a conclusion: the mankind sits in the millennia incorrectly!
It counted that during the working day of people, sitting on a chair, changes a pose about one thousand times! And every time tries to sit down more conveniently. To save people from infinite fidgeting, the scientist calculated "Akerbluma line" and created an ideal chair: inclined a seat inside, curved a back a little in that place where the backbone is bent... It became really much more convenient to sit.

What here began! What only chairs and chairs did not appear on light! With folding and sliding backs, head restraints, even with electroheating.
Everyone can choose on the taste.
