With this information, I finally choose Eliza Tinsley at 110.61, because Amazon is to vouch for its leather, the metal foot, despite its adjustable height than the picture we can not see the lever, but it is there and working.
I'm 1m77 and weighs 80 kg, the lowest setting my feet are flat on the floor, which is not necessarily visible in the photo folder, up to the kidneys, has a slight bulge pleasantly straightens his back, preventing me to add a cushion as on my old chair, which made the soul as well as oil on the floor of my office ...
I take off a star for the questionable quality of the metal used for different screws, these screws which attach using a socket wrench, the first one I screwed the key ended up turn in a vacuum, the tails of the screw head having finally disappeared, too much play between the key-framed and that of the screw head, I've remedied by using a key just my own box tool. Fortunately, there was added an additional screw to each set of screws, washers, as well as the screw-heads cache.
Before the introduction of live, uncluttered entrance bolts. Two, editing is better.
I write all this sitting in this chair and I am well installed, it is not upscale, but the value for money is balanced.
