We bought the Ikea BILLY / OXBERG Bookcase, brown ash veneer for our study room. We chose the one with glass door, as to keep the dust from entering. Brown / wood colour to match with the study table.
I fit the bookcase first before fitting the glass door.
Secure it to the wall. This is SUPER IMPORTANT and CRUCIAL, as the bookcase is TALL (2m) and can fall down easily. DO NOT SKIP THIS STEP.
Then I fitted the glass door to it. Assembling the bookcase is easier than the study table. See below for my Ikea study table blog post.
Even the glass door is easy to fit as well.
