This sounds like a fun social experiment - to see if you relationship can survive building Ikea furniture together. I would say the couple's mileage will vary based on the complexity of the job, their patience with themselves and each other. If atleast one of the two is a DIY enthusiast, then this would be a breeze and a fun way to collect $1000. Such pairs should almost be disqualified from participating for this experiment to yield results on the strength of the relationship stress-tested against an Ikea project.
My personal experience has been that I am too eager to skip Rule #1 - read the manual and underestimate the level of complexity. When you get started on the assembly project, it seems like all you need to do is apply commonsense and the pieces will come together. This is a big mistake and a person like me misremembers the depth of troubles this leads to not to mention time wasted. People are not assembling Ikea furniture on the regular. We forget the errors of our ways and repeat them on the next project to predictable outcomes.
