No so good as it supposed to be.
+ All details are in sets. Even a screwdriver. Easy to assemble. Armrests are wide and comfortable.
- Back is not really high. When sitting straight the headrest in its highest position pokes in shoulders even with my 176 cm height. Headrest is not comfortable. The place for fixing the back to the sitting place is short so it is difficult to use all 3 bolts. The mechanism for changing back inclination does not work properly as it changing nothing.
