The chair in black looks great. But there is the same problem in the assembly. The thread for the screws were poorly made. It goes in very difficult and the included screwdriver are also bad. One can not force it to act at all. I have to pay extra to rent a cordless screwdriver and rotate with pure power. Assembly lasts all one hour at me.
Next problem. The backrest is wrong after assembly, thus to the seat. No matter how you do it. It is wrong. And you know it when sitting.
The resin coating of the seat is also wrong. I've measured it. One side is 1 cm longer than the other. Well you sit on it so it looks and not all the time. But it just shows the poor processing. There is probably no product control during the production. No matter what the product looks like. Completed it will probably just go directly to the customer. Anyone unlucky caught just a bad product.
Finally, I must say, the chair is ok for the price. For 70 euros you can not expect good. I will not return to the chair, but again I'm going to buy him either. You have to just ask what you want.
