The bookcase is OK, but assembling it was quite a challenge! We hired someone through Wayfair/Angi for the installation, and he spent about 5 hours over two days working on it. Based on what he mentioned, the bookcase may not be easily moved once it's in place.
If you're worried about the bookcase being sturdy or in the right place, or if you think you might have to move it again later on, it might be worth reaching out to the service provider to clarify any concerns or possible solutions. Was there anything specific that made it so hard to move, like how heavy it was or how it was put together?
