How flat is your ceiling? I did the same with an Ikea wardrobe and had a few mm spare. Then when the door opened it caught on the ceiling a foot from the wall where the height was slightly uneven. Ended up shaving a bit off the corner of the door to let it open.
But yeah, it'll work, you might just need to build in place.
Pretty even and its a bookcase so no door to consider.
I wonder how flexible IKEA assembly instructions are as they say to assemble horizontal.
I'll find out tomorrow when it arrives.
