This chair looks great, but had a couple of significant issues.  The legs, which come in 2 sets of 2, must be attached.  But the screw holes did not align properly on either set of legs - both sets were off by 5-10 mm.  
Also, one of the chair arms feels just a little bit wobbly.  This is not a chair that will last forever, or more than 5 years!
The cushion is also very firm - no give at all. Comfortable for sitting cross-legged with the computer, but otherwise is not a chair I would sit in for a long period of time.
