Ergonomic chair, what it is and how it has to be

Comfort and a proper posture are often neglected when we are on a desk to work, meet other people or study, and this implies negative consequences on our health. During working or studying hours we spend plenty of time on a chair, which is often uncomfortable and not really ergonomic. In this situation it’s easy for many body parts to be severely tested. If we don’t have an ergonomic chair complying with the norm, this can imply muscular pain such as backake or tendinitis. The design of an ergonomic chair to work on a pc, to confront with other people, to study, call and, last but not least, to relax while waiting for a visit or meeting is today meticulously regulated by D.lgs 81/2008 and European directive EN 1335 1-2-3.
