IMPORTANT ADDENDUM: I have ordered me to chair one more time. Unfortunately, the second model is worse than the first. After only 2 days begins the tilting unit and gas spring on to squeak. Depending on which side the load is greater (right / left - Front / Rear) captures the chair suddenly crack. If you change the exposure light then, it cracks again and louder. This is really annoying.
At first I thought the screws may be tightened, nil. Completely dismantled and re-assembled, the exact same game. Apparently it is that causes the crack here inside the rocker unit .....
Too bad. The first is still good and shows the behavior does not, the second produced after two days already these unpleasant sounds ....
Now I understand the variety of reviews here. It splints on for luck to come which batch you caught ....
Again, I'll buy it no longer but look around for others. Deshlab also now only 2 star ...
