Dude IKEA doesn't care how things go together.
Every fucking time I buy IKEA shit it always comes out wiggly wobbly or something didn't quite align right or this or that or the other. It's cheap garbage.
Relatively recently decided to splurge on a bunk bed for the kids from a real furniture store that costs a little more.
Everything was tight, bro. Fit so good, and everything was just so sturdy and steady. Loved building it together with the wife as well. It was quite enjoyable.
I hate IKEA. Greetings from its motherland. 🙍♂️
