Tried a few chairs in this price range. The chair is indeed firm but with good lower back support. The chair is straight forward to put together, so simple that by looking at the simple instruction pictures you assume something will be missed in translation. No it really is a follow the pictures and you're done.
Its not meant to be a chair you sit on all day so for the price its good.

You need to assemble this chair with an instruction guide that contains only a picture. The chair is okay but you a better to spend a little more if you can since the seat is very firm.
