Drove 3 hours to a different state to go to IKEA. Finally bought the MALM bed frame and didn't know we needed wooden slats. Our old bed thing ended up fitting perfectly!

TLDR: Went to IKEA, three hours from home, and forgot to get slats for the bed. Hardware store was a half hour away, and I needed to sleep that night. : r/IKEA
