I ordered it by reading good reviews here and am happy with the product.
Whole thing came with a nice instruction to set it up. Only tool required is a hex/Allen key which is included in the shipping. It took about half an hour to assemble it alone. Another helping hand would make the assembly faster.

The assembled look is shown in attached photo!

Now about the chair:
It looks very sturdy. It is not very bulky and adjustable height and wheels make it exactly what I wanted. This looks great even without side arms and at some point I may simply remove them.

Just a note: The backrest part is fixed and doesn't recline backward (this is not a problem for me as I love to sit upright while working!)
