I saw some posts recommending Ikea's office chairs, so I'd like to share my experience with the Millberget that I bought in 2017.

The seat did crack at the bottom last year and the armrests start flaking by that time until I had to use cling wrap on the latter to prevent more of its pieces from falling to the ground. As for the former, I have to put a used towel on it. The backrest still holds up fine, tho.

I'd probably shop around for a better office chair one day, but not at this moment until I move into my new house.
