&lt;p&gt;Executive office chair, characterized by a high design and quality and certified by CATAS &quot;Ansi Bifma X 5.1&quot;.&lt;br&gt; &lt;br&gt; Main structure is entirely made of polypropylene, available white or black colour, while base and mechanism are made of aluminium. The back and the padded seat are covered with transpirant mech, grey colour: this chair has got soft castors, suitable also for parquet.&lt;br&gt;&lt;br&gt;The armrests are adjustable as standard, as well as the lumbar support and the head rests.&lt;br&gt;&lt;br&gt;The chair is equipped with a dedicated Syncro mechanism, with 5 locking positions and anti-shock system (which prevents the abrupt return of the seat in a vertical position). The mechanism is provided with tensioning device for adjusting the oscillation intensity, as well as for height adjustment of the seat.&lt;br&gt;Thanks to Syncro system, backrest and seat move simultaneously, so as to support all the points of the body, allowing relaxation and lengthening of legs and back. The fulcrum of the movement of the chair is positioned at the femoral pelvic area, so as to avoid uncoordinated movements and ensure a natural support.&lt;/p&gt;                            	    	                      	    	                      																				    	                      							    	                      				    	                      	    	                      	    	                                                                                                       &lt;p&gt;&lt;/p&gt;&lt;div class=&quot;sizes-and-weight-desc&quot;&gt;&lt;b&gt;Dimensions and weight&lt;/b&gt;&lt;table class=&quot;tDim cUfficio01&quot;&gt;&lt;tbody&gt;&lt;tr&gt;&lt;td class=&quot;tDim1&quot;&gt;&lt;span&gt;46 cm&lt;/span&gt;&lt;/td&gt;&lt;td class=&quot;tDim2&quot;&gt;&lt;span&gt;45.5 cm&lt;/span&gt;&lt;/td&gt;&lt;td class=&quot;tDim3&quot;&gt;&lt;span&gt;45-54 cm&lt;/span&gt;&lt;/td&gt;&lt;td class=&quot;tDim4&quot;&gt;&lt;span&gt;116-136 cm&lt;/span&gt;&lt;/td&gt;&lt;td class=&quot;tDim7&quot;&gt;&lt;span itemprop=&quot;weight&quot; itemscope=&quot;&quot; itemtype=&quot;http://schema.org/QuantitativeValue&quot;&gt;&lt;span itemprop=&quot;value&quot;&gt;21.2&lt;/span&gt; &lt;span itemprop=&quot;unitCode&quot;&gt;kg&lt;/span&gt;&lt;/span&gt;&lt;/td&gt;&lt;/tr&gt;&lt;/tbody&gt;&lt;/table&gt;&lt;/div&gt;
