The chair should be for my son, who comes in June to primary school, but the chair can only insofar be let down my! Can stand legs comfortable hanging my son in the air !!! So this referred to as school swivel chair item is not for Elementary Student suited all of which no 1.60 are great !! ??
Also at the back I find fault - when you sit down not give the backrest backwards, you sit quasi bent slightly forward - in a lumbar lordosis forced position! So, super uncomfortable! but which is important for the correct lumbar lordosis position height adjustment of the backrest is also not really possible, because it is only possible in a short period, and if you try the part too high to install, simply because his lumbar lordosis is up there, then the thing completely unstable and wobbly! from "grow" is no question there !!!
Then there's the possibility of the rest of the seat close to it or further away to fix, what can be done also very cumbersome and complicated and what is shaky even at low conversion!
All in all, the two knobs for adjusting useless and unnecessary!
So this chair looks more like he is !!! cheap processed, designed and manufactured cheap cheap, but it will cost too much money! I would also have a cheap furniture discounter can buy chair!
for next time rather spend a little more money and get a good chair for the a bit is functional !!!
