ᐅ How can I assemble Ikea Hemnes beds quickly and securely?

Hello everyone, I hope someone here can help me with a specific question. I recently bought an Ikea Hemnes bed and want to assemble it not only quickly but also securely. My goal is to follow the instructions as best as possible, but I’m uncertain about some steps, especially when it comes to connecting the side panels with the headboard and footboard. I’ve heard that you shouldn’t just tighten all the screws right away, but that there is a certain sequence or technique to ensure the bed is stable and not wobbly in the long run. Does anyone have experience or tips on how to assemble the Hemnes bed quickly yet solidly? Maybe also advice on tools or helpers that are particularly useful? Thanks in advance!
