By offering the paradox -example of the recent article of the Wall Street Journal, in which it is approached from different perspectives (including the commercial one) the problem of the workstation, namely in terms of sitting.

I mean for the back, as the " back ache" is the main reason of absence from work. "The secret of a back that is maintained in good condition, say the experts, is the posture. And in this case a bad seat has responsibility only for those who spend a full day on it. So what are the correct positions? "The thighs should be well supported by a seat not too soft," says Costanzo, "and remain parallel to ground, while the knees should be bent at right angles, to keep freed as much as possible lower limb joints ". At this point comes in the role the backrest, which should be equipped with a support for the lumbar region. It is the right way to ensure the functional posture to the physiological lordosis.
