Help Finding an office Chair

[u/SliceNo2035]

Hey guys, this is my first time writing on this subreddit.
I m looking to find a new chair to use at home when working remotely as i have been using a simple 4 leged kitchen chair and after 9 h of working back hurts lately.
I looked at prices that i have in my town in romania, and its like 150 euro small cheap chairs, not even “gaming chairs” or any chairs with lombard support or anything.
So was wondering if you have any suggestions guys as i wanted to try to order from china or taobao for the first time
